A direct-shift gearbox (DSG, German language: Direktschaltgetriebe ^[1])^{[ii] [3]} is an electronically-controlled, dual-clutch,^[two] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch performance, and with fully-automated^[2] or semi-manual gear selection. The first dual-clutch transmissions were derived from Porsche in-house evolution for the Porsche 962 in the 1980s.

In simple terms, a DSG automates 2 split "manual" gearboxes (and clutches) contained within one housing and working as ane unit of measurement.^{[2] [three] [4]} It was designed by BorgWarner and is licensed to the Volkswagen Group, with support past IAV GmbH.^{[ citation needed ]} By using two independent clutches,^{[two] [iv]} a DSG can achieve faster shift times^{[2] [4]} and eliminates the torque converter of a conventional epicyclic automatic transmission.^[two]

Overview [edit]

Transverse DSG [edit]

At the time of launch in 2003,^{[two] [five]} it became the globe's showtime automated dual-clutch transmission in a series-production machine,^{[ii] [5]} in the German-market place Volkswagen Golf Mk4 R32,^{[2] [5]} and shortly subsequently worldwide, in the original Audi TT three.2.^[six] and the 2004+ New Beetle TDI. For the first few years of production, this original DSG transmission was only available in transversely oriented^[2] front end-engine, front-wheel-bulldoze and Haldex Traction-based four-cycle-drive vehicle layouts.

The first DSG transaxle that went into production for the Volkswagen Group mainstream marques had six forwards speeds (and one reverse)^{[v] [six]} and used wet/submerged multi-plate clutch packs^[2] (Volkswagen Grouping internal lawmaking: DQ250, parts code prefix: 02E).^{[six] [vii]} It has been paired to engines with up to 350 N⋅thousand (260 lb⋅ft) of torque.^{[5] [6]} The ii-wheel-bulldoze version weighs 93 kg (205 lb). Information technology is manufactured at Volkswagen Group'south Kassel plant,^[2] with a daily production output of one,500 units.^[5]

At the start of 2008, some other world-first^[5] 70 kg (150 lb) seven-speed DSG transaxle^[5] (Volkswagen Group internal code: DQ200, parts code prefix: 0AM)^{[vii] [8] [9]} became available. Information technology differs from the 6-speed DSG, in that it uses ii single-plate dry clutches (of similar diameter).^[9] This clutch pack was designed past LuK Clutch Systems, Gmbh.^[10] This vii-speed DSG is used in smaller front-bicycle-bulldoze cars with smaller-displacement engines with lower torque outputs,^{[v] [half dozen] [9]} such as the latest Volkswagen Golf,^{[five] [9]} Volkswagen Polo Mk5,^[9] and the new SEAT Ibiza.^[6] Information technology has been paired to engines with upwardly to 250 North⋅chiliad (180 lb⋅ft).^[11] Information technology has considerably less oil capacity than the six-speed DQ250; this new DQ200 uses but 1.seven litres (0.37 imp gal; 0.45 The states gal) of transmission fluid.^[5]

In September 2010, VW launched a new seven-speed DSG built to support upwards to 600 N⋅m (440 lb⋅ft), the DQ500.^[12]

Audi longitudinal DSG [edit]

In late 2008, an all-new 7-speed longitudinal^{[6] [13]} S tronic ^[13] version of the DSG transaxle went into series product (Volkswagen Group internal code: DL501, parts code prefix: 0B5).^[7] Initially, from early 2009, it is only used in sure Audi cars, and just with longitudinally mounted engines. Like the original six-speed DSG, it features a concentric dual wet multi-plate clutch.^[13] Still, this particular variant uses notably more plates – the larger outer clutch (for the odd-numbered gears) uses 10 plates, whereas the smaller inner clutch (driving even-numbered gears and reverse) uses 12 plates.^[13] Some other notable modify over the original transverse DSGs is the lubrication system^{[14] [15]} – Audi now employ two totally separate oil circuits.^[thirteen] One oil circuit, consisting of 7.five litres (ane.65 imp gal; one.98 US gal), lubricates the hydraulic clutches and mechatronics with fully synthetic specialist automatic transmission fluid (ATF),^[13] whilst the other oil circuit lubricates the gear trains and front and centre differentials with 4.iii litres (0.95 imp gal; 1.xiv US gal) of conventional hypoid gear oil.^[13] This dual circuit lubrication is aimed at increasing overall reliability, due to eliminating cross-contamination of debris and habiliment particles.^[13] It has a torque handling limit of up to 600 Due north⋅m (440 lb⋅ft),^[6] and engine ability outputs of up to 330 kW (450 PS; 440 bhp).^[6] It has a total mass, including all lubricants and the dual-mass flywheel of 141.5 kg (312 lb).^{[half dozen]}

This was initially bachelor in their quattro all-wheel-drive variants,^[seven] and is very similar to the new ZF Friedrichshafen-supplied^[16] Porsche Doppel-Kupplung (PDK).^{[17] [18]}

Operational introduction [edit]

The internal combustion engine drives two clutch packs.^{[2] [4]} The outer clutch pack drives gears 1, three, five^[2] (and 7 when fitted), and reverse^[2] – the outer clutch pack has a larger bore compared to the inner clutch, and can therefore handle greater torque loadings. The inner clutch pack drives gears ii, 4, and half dozen.^[2] Instead of a standard large dry unmarried-plate clutch, each clutch pack for the 6-speed DSG is a collection of four modest wet interleaved clutch plates (similar to a motorbike moisture multi-plate clutch). Due to space constraints, the two clutch assemblies are concentric, and the shafts within the gearbox are hollow and likewise concentric.^[four] Because the alternate clutch pack's gear-sets can be pre-selected^{[2] [four]} (predictive shifts enabled via the unloaded section of the gearbox), un-powered time while shifting is avoided^{[two] [4]} because the transmission of torque is only switched from one clutch-pack to the other.^[2] While the DSG has one of the fastest shift times on the marketplace, the claim that the DSG takes simply about 8 milliseconds to upshift is united nations-proven with 3-political party data nor claimed past the manufacturer.

DSG controls [edit]

The directly-shift gearbox uses a floor-mounted transmission shift lever, very similar to that of a conventional automatic transmission.^[nine] The lever is operated in a straight 'fore and aft' plane (without any 'dog-leg' starting time movements), and uses an boosted button to help prevent an inadvertent selection of an inappropriate shift lever position.

P [edit]

P position of the flooring-mounted gear shift lever ways that the transmission is set in park. Both clutch packs are fully disengaged, all gear-sets are disengaged, and a solid mechanical transmission lock is applied to the crown wheel of the DSG'south internal differential. This position must only be used when the motor vehicle is stationary. Furthermore, this is the position which must be set on the shift lever earlier the vehicle ignition key can be removed.

N [edit]

N position of the floor-mounted shift lever means that the transmission is in neutral. Like to P higher up, both clutch packs and all gear-sets are fully disengaged; all the same, the parking lock is likewise disengaged.

D mode [edit]

Whilst the motor vehicle is stationary and in neutral (Due north), the driver tin can select D for drive (after get-go pressing the foot brake pedal). The transmission'south outer clutch K2 engages at the start of the seize with teeth point, while on the alternate gear shaft the reverse gear clutch K1 is also selected.^{[2] [3]} The clutch pack for second gear (K2) gets prepare to engage. When the driver releases the brake pedal, the K2 clutch clamping force is increased, allowing the manual to drive the wheels. Depressing the accelerator pedal engages the clutch and causes an increase of forrard vehicle speed. Pressing the throttle pedal to the floor (hard dispatch) will cause the gearbox to "kick down" to first gear to provide the acceleration associated with first, although there will be a slight hesitation while the gearbox deselects second gear and selects start gear. As the vehicle accelerates, the transmission's calculator determines when the second gear (which is connected to the 2d clutch) should be fully used. Depending on the vehicle speed and amount of engine power being requested by the driver (determined by the position of the throttle pedal), the DSG then up-shifts. During this sequence, the DSG disengages the first outer clutch whilst simultaneously engaging the second inner clutch^{[ii] [three]} (all power from the engine is now going through the second shaft), thus completing the shift sequence. This sequence in a fraction of a 2d (aided by pre-choice), and can exist performed without lifting off the throttle, resulting in minimal ability loss.^[2]

Once the vehicle has completed the shift to second gear, the first gear is immediately de-selected, and 3rd gear is pre-selected.^{[two] [iii]} In one case the time comes to shift into 3rd, the second clutch disengages and the starting time clutch re-engages.^[2] This sequence repeats through the gear changes.

Downshifting is like to up-shifting but in reverse order. At 600 milliseconds downshifting is necessarily slower, due to the engine'southward Electronic Control Unit of measurement (ECU) needing to 'blip' the throttle so that the engine crankshaft speed can lucifer the advisable gear shaft speed.^[2] A downshift occurs when the ECU senses the auto slowing down, or when more than power is required.

The bodily shift points are determined by the DSG'southward transmission ECU, which controls a hydro-mechanical unit of measurement.^[2] The transmission ECU, combined with the hydro-mechanical unit, are collectively called a mechatronics ^[2] unit of measurement or module. Because the DSG's ECU uses fuzzy logic, the functioning of the DSG is said to be adaptive;^{[ dubious – discuss ]} that is, the DSG volition "larn" how the user drives the car, and will progressively tailor the shift points appropriately to suit the habits of the driver.^{[ citation needed ]}

In the vehicle instrument display, between the speedometer and tachometer, the available shift-lever positions are shown, the current position of the shift-lever is highlighted (emboldened), and the electric current gear ratio in use is too displayed as a number.

Under "normal", progressive and linear dispatch and deceleration, the DSG shifts in a sequential manner; i.e., under acceleration: 1st → 2nd → tertiary → 4th → fifth → 6th, and the aforementioned sequence reversed for deceleration. Still, the DSG can as well skip the normal sequential method, past missing gears, and shift two or more than gears.^[three] This is most apparent if the automobile is being driven at sedate speeds in one of the college gears with a light throttle opening, and the accelerator pedal is then pressed downwards, engaging the kick-down function. During kicking-down, the DSG will skip gears,^[ix] shifting straight to the virtually appropriate gear depending on speed and throttle opening. This kick-down may be engaged by any increased accelerator pedal opening, and is completely independent of the additional resistance to be institute when the pedal is pressed fully to the floor, which will actuate a similar kick-down office when in Manual operation fashion. The vii-speed unit in the 2007 Audi variants will non automatically shift to 6th gear; rather, information technology stays at fifth to proceed power available at a high RPM while cruising.^{[ citation needed ]}

When the floor-mounted gear selector lever is in position D, the DSG works in fully automatic mode,^{[iii] [4]} with accent placed on gear shifts programmed to evangelize maximum fuel economy.^{[iii] [9]} That means that shifts volition change up and down very early on in the rev-range. As an example, on the Volkswagen Golf Mk5 GTI, sixth gear volition be engaged around 52 km/h (32 mph), when initially using the DSG transmission with the default ECU adaptation; although with an "ambitious" or "sporty" driving style, the adaptive shift blueprint will increase the vehicle speed at which 6th gear engages.

Southward fashion [edit]

The floor selector lever also has an S position.^[ii] When S is selected, sport style^[ii] is activated in the DSG. Sport style still functions as a fully automatic mode,^[3] identical in operation to D mode, but upshifts and downshifts are made much higher up the engine rev-range.^{[2] [iii] [9]} This aids a more sporty driving manner,^[two] by utilising considerably more of the bachelor engine power, and also maximising engine braking. Notwithstanding, this mode does have a detrimental effect on the vehicle fuel consumption, when compared to D mode. This mode may not be platonic to use when wanting to drive in a sedate style; nor when road conditions are very slippery, due to water ice, snow or torrential rain – because loss of tire traction may be experienced (wheel spin during acceleration, and may as well result in road wheel locking during downshifts at high engine rpms under closed throttle). On 4motion or quattro-equipped vehicles this may be partially offset past the drivetrain maintaining full-fourth dimension date of the rear differential in S way, and so ability distribution under loss of front-bicycle traction may be marginally improved.

Southward is highlighted in the musical instrument brandish, and like D way, the currently used gear ratio is also displayed as a number.

R [edit]

R position of the floor-mounted shift lever means that the transmission is in reverse. This functions in a similar way to D, simply in that location is merely one contrary gear. When selected, R is highlighted in the instrument display.

Manual fashion [edit]

Additionally, the floor shift lever also has another plane of operation, for manual ^{[three] [4]} mode, with leap-loaded + and − positions. This plane is selected by moving the stick away from the driver (in vehicles with the driver's seat on the right, the lever is pushed to the left, and in left-hand drive cars, the stick is pushed to the right) when in D manner only. When this aeroplane is selected, the DSG tin now be controlled like a manual gearbox, albeit merely under a sequential shift blueprint.

In most (VW) applications, the readout in the instrument display changes to half-dozen 5 four three 2 ane, and merely like the automatic modes, the currently used gear ratio is highlighted or emboldened. In other versions (due east.yard., on the Audi TT) the display shows just M followed by the gear currently selected; e.g., M1, M2, etc.

To modify up a gear, the lever is pushed forward (against a spring force per unit area) towards the +, and to modify down, the lever is pulled rearward towards the −. The DSG transmission can now be operated with the gear changes being (primarily) determined past the driver. This method of performance is usually called tiptronic.^[2] In the interests of engine preservation, when accelerating in Transmission/tiptronic style, the DSG volition still automatically change up just before the redline, and when decelerating, it will change down automatically at very low revs, merely before the engine idle speed (tickover). Furthermore, if the driver calls for a gear when information technology is non appropriate (east.k., requesting a downshift when engine speed is well-nigh the redline) the DSG will not alter to the driver's requested gear.^[3]

Electric current variants of the DSG volition still downshift to the lowest possible gear ratio when the kick-downwardly button is activated during full throttle whilst in manual style. In Manual fashion this kick-downwards is simply activated by an boosted button at the bottom of the accelerator pedal travel; unless this is pressed the DSG will not downshift, and will simply perform a full-throttle acceleration in whatever gear was previously existence utilised.

Paddle shifters [edit]

Initially^{[ when? ]} bachelor on certain^{[ example needed ]} high-powered^{[ quantify ]} cars, and those with a "sporty"^{[ further explanation needed ]} trim level—such as those using the ii.0 T FSI and 3.ii/3.6 VR6 engines^[two]—steering wheel-mounted paddle shifters ^{[three] [4]} were available. However, these are now being offered (either as a standard inclusive fitment, or as a manufactory optional extra) on about all DSG-equipped cars, throughout all model ranges, including bottom ability output applications, such as the 105 PS Volkswagen Golf Plus.^[9]

These operate in an identical manner equally the flooring mounted shift lever when it is placed across the gate in manual mode. The paddle shifters accept two singled-out advantages: the driver tin can safely keep both easily on the steering wheel when using the Manual/tiptronic mode; and the driver tin temporarily manually override either of the automatic programmes (D or Southward),^[9] and proceeds instant manual command of the DSG transmission^[nine] (within the higher up described constraints).

If the paddle-shift activated manual override of one of the automatic modes (D or S) is used intermittently the DSG transmission will default back to the previously selected automatic mode after a predetermined elapsing of inactivity of the paddles, or when the vehicle becomes stationary. Alternatively, should the driver wish to immediately revert to fully automatic command, this tin can be done by activating and holding the + paddle^[9] for at least two seconds.

Advantages and disadvantages [edit]

Advantages [edit]

• Better fuel economy^{[2] [five]} (upwards to xv% improvement) than conventional planetary geared automatic transmission (due to lower parasitic losses from oil churning)^[4] and for some models with manual transmissions;^[ii]
• No loss of torque through the transmission from the engine to the driving wheels during up-shifts;^{[2] [4]}
• Short upwardly-shift time when shifting to a gear the alternating gear shaft has preselected;
• Smooth gear-shift operations;^[four]
• Consequent downwards-shift time of 600 milliseconds, regardless of throttle or operational manner;

Disadvantages [edit]

• The clutch pack mechanisms have a limited lifespan;
• Marginally worse mechanical efficiency compared to a conventional transmission manual, particularly on moisture-clutch variants due to electronics and hydraulic systems;^[four]
• Expensive specialist transmission fluids/lubricants with dedicated additives are required, which need regular changes;^{[14] [fifteen]}
• Relatively expensive to manufacture,^{[ citation needed ]} and therefore increases new vehicle purchase toll;
• Relatively lengthy shift time when shifting to a gear ratio which the transmission control unit did not conceptualize (effectually 1100 ms, depending on the situation);^[27]
• Torque handling capability constraints impose a limit on subsequently-market place engine tuning modifications (though many tuners and users may exceed the official torque limits still); (After variants have been fitted to more powerful cars, such as the 300 bhp/350 Nm VW R36 and the 272 bhp/350 Nm Audi TTS.)
• Heavier than a comparable Getrag conventional manual transmission (75 kg (165 lb) vs. 47.5 kg (105 lb));

Problems and recalls of DSG-equipped vehicles [edit]

The vii-speed DQ200 and six-speed DQ250 gearboxes sometimes suffer from power-loss (gear disengaging) due to short-circuiting of wires caused by a build-up of sulphur in the transmission oil.^[30]

Usa [edit]

In August 2009, Volkswagen of America issued two recalls of DSG-equipped vehicles. The first involved 13,500 vehicles,^[31] and was to address unplanned shifts to the neutral gear,^[31] while the 2nd involved like problems (by and then attributed to faulty temperature sensors) and applied to 53,300 vehicles.^{[31] [32] [33]} These recalls arose as a outcome of investigations carried out by the US National Highway Traffic Safe Administration (NHTSA),^[34] where owners reported to the NHTSA a loss of power whilst driving.^[31] This investigation preliminary found only 2008 and 2009 model yr vehicles as existence affected.^{[31] [34]}

Commonwealth of australia [edit]

In November 2009, Volkswagen recalled certain Golf game, Jetta, EOS, Passat & Caddy models equipped with half dozen-speed DQ250 DSG transmission because the gearbox may read the clutch temperature incorrectly, which leads to clutch protection mode, causing a loss of power.^[35]

China [edit]

Since 2009 there have been widespread concerns from Chinese consumers especially among the online community, who expressed that Volkswagen has failed to reply to complaints about defects in its DSG-equipped vehicles. Typical issues associated with 6-speed DSG include abnormal noise and inability to change gear; while problems associated with 7-speed DSG include aberrant noise, excessive shift shock, aberrant increase in engine RPM, flashing gear indicator on the dashboard besides as inability to shift to even-numbered gears.^{[ citation needed ]} In March 2012 Prc's quality watchdog the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) said that it had been in contact with Volkswagen (Red china) and urged the carmaker to probe the issues.^{[36] [37]} In a survey held by Gasgoo.com (China) of 2,937 industry experts and insiders, 83% of respondents believed that the carmaker should consider a full vehicle recall.^[38] In March 2012 Volkswagen Group Cathay admitted that in that location could be an issue in its 7-speed DSG gearboxes that may impact approximately 500,000 vehicles from its diverse subsidiaries in China.^[39] A software upgrade has since been offered for the afflicted vehicles in an attempt to repair the problem.

According to 163.com - one of China's virtually pop web portals - in March 2012 about a quarter of the complaints about bug establish in cars in China'due south automotive market were fabricated against DSG-equipped vehicles manufactured by Volkswagen.^[xl] The summit five models that boss those complaints were:

• Volkswagen Magotan - 6%
• Volkswagen Bora - v.3%
• Volkswagen Sagitar - v.3%
• Volkswagen Touareg - iv.vii%
• Volkswagen Golf game - 4%

Would be worth noting that Touareg has never been fitted with a DSG manual.

On 15 March 2013, China Key Boob tube aired a program for the World Consumer Rights Day. The program criticized the issue associated with DSG-equipped vehicles manufactured past Volkswagen. On 17 March 2013 Volkswagen Group China announced on its official Weibo that it will voluntarily recall vehicles equipped with DSG boxes.^[41] Some sources have estimated the failure rate of DSG-equipped vehicles sold in Red china to be greater than 20,000 per million sold.^{[ citation needed ]}

Sweden [edit]

VW Sweden stopped selling the Passat EcoFuel DSG as a taxi after many cars had problems with the 7 speed DSG gearbox. They instead offered the Touran EcoFuel DSG, which uses an updated version of the same DSG gearbox.^[42]

Nihon [edit]

The retrieve has been extended to Nippon with 91,000 (VW and Audi using the same DSG) being recalled.^[43]

Malaysia [edit]

xiii days after the Singapore recall, Volkswagen Malaysia also announced a recall for the 7-speed DSG. No official statement was released by the visitor, but it was stated that a full of 3,962 were involved in the unit remember exercise - units produced between June 2010 and June 2011, with affected vehicles being Golf game, Polo, Scirocco, Cantankerous Touran, Passat and Jetta models equipped with the transmission.^[44]

Australian call back [edit]

xv October 2019, Commonwealth of australia recall of DSG 7-speed gearboxes. Due to a production error, over time a crevice in the transmissions pressure accumulator tin occur. If the pressure level accumulator cracks, oil and pressure level is lost in the hydraulic system of the gearbox. As a outcome, the manual of engine ability via the gearbox is interrupted. The feel of this symptom would be comparable to depressing the clutch in a vehicle fitted with a manual transmission. This could increase the likelihood of an accident affecting the occupants of the vehicle and other road users.^[45]
