Multitronic 0AW (2007-2014)2007–2014 · 0AW
With cautionIt notably improves on the 01J's reliability, above all in the control unit, but none of the sources consulted says it completely eliminates chain wear or jerking when pulling away; apply the same checks as for the 01J before buying.[6]
Faults that affect the A6 C7
- Critical severityFrequency: CommonTransmissionWear of the variator chain and conesYes: the variator uses a chain of more than 1,000 links between two pairs of cones that wears with mileage, especially if the oil is not changed regularly. Gebrauchtwagenberater ties the gearbox's reputation to "numerous total failures"; Schaeffler/LuK sells a kit to repair the chain.
- High severityFrequency: CommonElectronicsControl unit (TCU) failure and limp modeYes: the multitronic control unit, especially in the 01J code (up to 2007), is one of its best-documented weak points. Overheating with oil seeping into the control unit causes fault warnings and limp mode and, if ignored, can end up damaging the gearbox itself.
- Medium severityFrequency: CommonClutchJerking and vibration when pulling away from cold (multi-plate clutch)Yes: with no torque converter, the multitronic pulls away using an electronic multi-plate clutch that can jerk or vibrate, especially when cold, if its plates are worn or the oil no longer has the right properties. It is one of the most cited fault symptoms of this gearbox.

With cautionOwner reports repeat injection faults on the 313 hp (3 of 13 on the Q5 and 4 of 14 on the A6 C7), although there are few cases and no official statistics.[8][13]
3.0 TDI EA897 evo, Euro 6 (CRTC, CRTD, CRTE, CRTF, CZVA, CSWB, DDXB and others; 2014-2020)2014–2020 · 163–272 hp · CRTC, CRTD, CRTE, CRTF, CZVA, CZVB, CZVC, CZVE, CZVF, CSWB, CVZA, CVVB, DDXA, DDXB, DDXC, DDXE
With cautionThe CRT and CZV series from 2014 to early 2017 have an Audi bulletin for possible camshaft breakage: check the engine number and whether they were replaced. The 200 kW A6 and A7 also went through the KBA recall.[3][10][14][15]
Faults that affect the A6 C7
Only those that affect the versions and years that this car used. The 3.0 TDI V6 has 7 documented faults in total.
- High severityFrequency: CommonCoolingFailing water pump and cooling system leaksOn the 3.0 TDI the water pump can fail and, from 2010, overheat to the point of damaging the engine (the A6 C6 guide cites a service action). Owners also cite coolant leaks from hoses, the regulating valve and the cooler.
- Critical severityFrequency: OccasionalTimingCamshaft breakage on the EA897 evo (CRT and CZV)On the EA897 evo engines from 2014 to early 2017 (mainly CRT, also CZV) the camshafts can break because of a material or design defect, according to the guides. Audi lists it in bulletin TPI 2043172 and the problem was considered under control from February 2017.
- High severityFrequency: OccasionalTimingTiming chain stretch and tensioner wearOn the 3.0 TDI V6 the timing chain is at the gearbox end and its tensioner can lose tension: it rattles on a cold start and, if the chain stretches, the timing goes out and the engine is at risk. Replacing it means opening the engine and costs several thousand euros.
- High severityFrequency: OccasionalInjectionInjector wear (needle seat) and injection faultsGerman guides point to wear of the needle seat of the 3.0 TDI injectors: they stop closing properly, diesel drips into the cylinder and dilutes the oil. Smoke from the exhaust can be the warning, and reports on the 313 hp twin-turbo repeat injection faults.
- Medium severityFrequency: CommonEmissions controlControl unit software with a prohibited emissions strategy (NOx and AdBlue)Germany's KBA ordered a software update for the Euro 5 and 6 3.0 TDI V6 engines from Audi, VW and Porsche: a warm-up strategy that reduced NOx only on the test bench and, on the 200 kW A6 and A7, limited AdBlue dosing. The update is free.Repair: €0

With cautionThis is the production window covered by the 2015 fuel rail campaign (built between April 2011 and April 2012) and the one a workshop singles out for chain and tensioner wear (2011-2014); check that the campaign has been carried out.[19][20][21]
3.0 TFSI 333 hp evo supercharged with combined injection (CREC; 2014-2018)2014–2018 · 333 hp · CREC
With cautionThe supporting indirect injection should ease carbon build-up (no source measures this) and a workshop says the chain gives fewer problems from 2014, but these units fall under the 2019 low-pressure rail campaign: confirm by VIN that it has been done.[16][20][21][22]
Faults that affect the A6 C7
- High severityFrequency: OccasionalTimingTiming chain stretch and tensioner wearA German workshop describes chain stretch and marginal tensioners in the first supercharged 3.0 TFSI engines (2011-2014), with noise on cold starts and codes P0016-P0018; other guides consider it rare in this V6. There are no reliable statistics.
- High severityFrequency: OccasionalFuelFuel leak at the injection rails (2015 and 2019 campaigns)Audi recalled cars with the 3.0 TFSI over possible leaks from the fuel rails: one campaign in 2015 (built between April 2011 and April 2012) and another in 2019 (low-pressure rails, built between 2014 and 2016). You notice it by a smell of petrol; the fix is to replace the rails.
- Medium severityFrequency: OccasionalCoolingLeak at the thermostat housing and water pumpTechnical guides cite coolant leaks from the plastic thermostat housing and from the water pump of the supercharged 3.0 TFSI, and Audi also replaced the thermostat in a 2015 campaign. You notice it by falling coolant and, if ignored, by overheating.
- Low severityFrequency: CommonIntakeCarbon build-up on the intake valves (direct injection)Like any direct-injection engine, the 3.0 TFSI accumulates carbon on the intake valves, because the fuel does not wash them; guides put it at around 95,000 km and it causes rough idle and loss of power. The 333 hp versions from 2014 add indirect injection.
- Low severityFrequency: OccasionalLubricationPCV valve failure (crankcase ventilation)The PCV valve in the 3.0 TFSI's crankcase ventilation can fail with age and mileage: parts supplier and workshop guides cite rough idle, vacuum leaks and higher oil consumption. It is a minor fault, with no campaign or published statistics.

BuyIt is the most widespread version and the one with the most known mileage: in the analyses of several models (BMW X3, BMW X5, Audi A6) gearbox faults are a minority of the total accounts, although occasional jerking is still documented and, less often, mechatronic faults or leaks. It is worth checking the history, but there is no systemic defect that argues against buying.[2][24][25]
Faults that affect the A6 C7
- High severityFrequency: OccasionalElectronicsMechatronic failure as the gearbox ages (sometimes with reverse)Yes, although in a minority of cases: there are documented ZF 8HP mechatronic failures on BMW after 120,000-130,000 km, costing €1,400 to €3,500, and also control unit or electronic selector faults on Audi and Land Rover.Repair: €1,400–€3,500
- Medium severityFrequency: CommonTransmissionJerking and hesitation when changing gear, sometimes needing reprogrammingYes: on BMW, Audi, Jaguar and Alfa Romeo there are accounts of jerking, hesitation or harsh shifts with the ZF 8HP. It is usually due to ageing oil or the calibration of the mechatronics, and the dealer often fixes it -not always first time- by reprogramming the gearbox control unit.
- Medium severityFrequency: OccasionalLubricationOil leaks from the gearbox gaskets or sumpYes: on the BMW 1 Series and the Jaguar F-Pace there are accounts of oil leaks from the ZF 8HP gearbox gaskets, in one case already at 40,000 km. If it is not repaired soon, the loss of pressure can speed up internal wear and lead to the jerking or mechatronic failure of the related faults.Repair (garage): €1,000–€2,000

Faults that affect the A6 C7
Only those that affect the versions and years that this car used. The 2.0 TDI has 8 documented faults in total.
- Medium severityFrequency: CommonCoolingCoolant loss from the water pump or the coolersMany 2.0 TDI engines lose coolant. On the 150 hp EA288 the water pump is usually the culprit and, more rarely, the cylinder head; on the 140 hp EA189 the typical causes are the oil cooler or the EGR cooler.
- Low severityFrequency: RareTurboHissing when accelerating from damaged hoses or intercooler on the Transporter T6 2.0 TDIOn the Transporter T6 2.0 TDI (2015-2019) a hissing sound can be heard when accelerating, caused by loose or damaged hoses or a crack in the intercooler. Often there is no loss of power and no warning light; oil stains reveal the crack.
Faults of the Audi A6 C7 outside the engine
Suspension, brakes, tyres, electronics and the rest of the car. They occur with any engine.
Suspension
- Medium severityFrequency: OccasionalSuspensionPremature wheel bearing wearAccording to testimonies collected by fiches-auto.fr, there are cases of wheel bearings replaced between 85,000 and 193,000 km on the A6 C7. You notice it as a hum that grows with speed.
- Medium severityFrequency: RareSuspensionRear air suspension leaks and compressor failureAccording to testimonies collected by fiches-auto.fr, some A6 C7 cars with air suspension lose air in the rear bellows or need a new compressor, with cases from around 80,000 km. It is a fault cited by few owners.
- Medium severityFrequency: RareSuspensionBall joints, steering track rod ends and brake lines flagged in TÜV inspectionsGebrauchtwagenberater.de notes that, although the A6 C7 scores well in the TÜV report, inspectors sometimes flag the brake lines and, on high-mileage cars, the suspension ball joints and the steering track rod ends.
