Audi A4 B8 problems (2007–2015)

All 4 engines and 1 gearbox of the Audi A4 B8 that we have documented have high or critical severity faults: the Multitronic gearbox, the 2.0 TSI / TFSI, the 3.0 TDI V6, the 2.0 TDI and the Audi 3.0 TFSI V6. The safest option is the 2.0 TDI in its 2.0 TDI EA288 (from 2012) version, with a «Buy» verdict.[1]

Outside the engine: Outside the engine, the most important notice for the A4 B8 is Takata recall 69EQ, which covers units built up to August 2011. There was also a 2012 recall for oil in the brake servo. The other documented points are isolated notices about power steering after driving through heavy rain and MMI infotainment system lock-ups, with no official recall attached.[2][3][4][5]

    With caution

    It 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.[8]

Faults that affect the A4 B8

  1. 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.
  2. 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.
  3. 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.

Faults that affect the A4 B8

  1. High severityFrequency: CommonLubricationHigh oil consumptionIt is the most repeated complaint on first-batch EA888s (2008-2012) and still appears, to a lesser extent, in later generations. The engine needs topping up between services with no visible leak or obvious smoke at first.Repair (garage): €1,500–€4,000
  2. Critical severityFrequency: OccasionalTimingTiming chain and tensioner wearOver the years, the chain can stretch and the hydraulic tensioner can stop keeping it taut, especially on first-batch units (2008-2012). If the chain jumps a tooth, it can slam the valves into the pistons.
  3. Medium severityFrequency: Very frequentIntakeCarbon build-up on the intake valvesBecause the fuel is injected directly into the cylinder, no petrol washes over the intake valves, so oil residue and soot build up and, over the years, restrict airflow and affect engine response.
  4. Medium severityFrequency: CommonCoolingThermostat housing leak and water pump failureSince Volkswagen integrated the water pump impeller into the thermostat housing, this plastic part leaks coolant over time; on the oldest units, with a separate belt-driven pump, failures of the pump itself are also documented.
  5. Low severityFrequency: OccasionalLubricationPCV valve (crankcase ventilation) failureThe PCV valve returns to the intake manifold the oil and combustion vapours that build up in the crankcase. If it sticks closed or open, it causes a rough idle, misfires or oil leaks from the seals.Repair (garage): €60–€250

Faults that affect the A4 B8

Only those that affect the versions and years that this car used. The 3.0 TDI V6 has 7 documented faults in total.

  1. 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.
  2. 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.
  3. 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.
  4. 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
  5. Medium severityFrequency: CommonEmissions controlFaulty EGR valve and EGR coolerOn the first-generation EA896 engines the EGR valve and cooler often fail: Audi talks about around 15% of units compared with 1-2 in every 1,000 in the second generation (a figure cited by Wikipedia). The cooler clogs with soot and can lose coolant.
  6. Medium severityFrequency: OccasionalIntakeWorn intake flaps (swirl) and intake manifoldOn V6 TDI engines from 2004 to 2010 the control of the intake (swirl) flaps can develop play and turn on the engine warning light with code P3134. Hella says the flap and actuator form one unit and are replaced together; on the Q7 4L it is the category owners cite most.

    Worth buying if the emissions update has been done and, on 2009-2011 units, the diesel pipe campaign, and if there are no symptoms of EGR, particulate filter or turbo problems. Caradisiac finds it hard to recommend the Audi A4 2.0 TDI of this era because of its reliability problems.[20][22][23]

    Caradisiac picks it as the best diesel in the third-generation Audi A3. Its most cited fault is coolant loss from water pump leaks, easy to keep an eye on before buying.[1]

Faults that affect the A4 B8

Only those that affect the versions and years that this car used. The 2.0 TDI has 8 documented faults in total.

  1. Medium severityFrequency: Very frequentEmissions controlManipulated emissions software (dieselgate) and the subsequent updateThe 2.0 TDI EA189 (2008-2015) had software that reduced the EGR outside type-approval tests. Volkswagen fixes it free of charge with an update of about 30 minutes, which is not mandatory to pass the ITV (Spain's roadworthiness inspection, similar to the MOT) and whose long-term effects are still under discussion.Repair: €0
  2. High severityFrequency: OccasionalInjectionHigh-pressure pump, injectors and diesel leaks on the EA189On the 2.0 TDI EA189, the high-pressure pump can shed metal particles that force the pump and injectors to be replaced. In addition, 2009-2011 units were recalled for diesel leaks from the high-pressure pipes.
  3. High severityFrequency: OccasionalTurboTurbo with seized vanes or premature failureOn the 110 and 140 hp 2.0 TDI engines, the vanes of the variable-geometry turbo get dirty and seize and the engine loses power. On some 140 hp units the turbo has failed before 70,000 km.Repair (garage): €1,000
  4. Medium severityFrequency: CommonEmissions controlDirty EGR valve and EGR cooler leaksThe 2.0 TDI's EGR valve often fills with carbon, especially with short journeys, and causes smoke and loss of power. On the EA189, the EGR cooler can also lose coolant.Repair (garage): €100–€300
  5. Medium severityFrequency: CommonEmissions controlClogged particulate filter or faulty pressure sensorThe 2.0 TDI's particulate filter clogs if the car mostly makes short journeys, because it never gets to regenerate; sometimes the fault is just the differential pressure sensor. Cleaning it costs around €200 and replacing it, €800 to €3,000.Repair (garage): €800–€3,000
  6. 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.
  7. 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 that affect the A4 B8

Only those that affect the versions and years that this car used. The Audi 3.0 TFSI V6 has 5 documented faults in total.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
