3 important faults

critical1

2.7 / 3.0 TDI V6: the rear timing chain and the oil pump drive

critical

The timing chain of the longitudinal V6 diesel runs at the back of the engine, on the gearbox side, so replacing it means taking out the engine or the gearbox. That alone makes it expensive, but the mechanism is the point: the chains stretch and the hydraulic tensioners lose their pressure. The first and only early sign is a 2 to 3 second metallic rattle audible on a cold start. If that is ignored, the chain jumps or breaks, and the engine is badly damaged inside. The same chain kit also drives the oil pump: if that seizes, the engine is left without lubrication.

What to check

  • Start it cold, in a quiet place, with the bonnet open: the rattle is audible in the first 2 to 3 seconds
  • Stand at the gearbox side of the engine: the noise comes from there, not from the front
  • Ask whether the chain and the tensioner were replaced, and ask for the invoice (it involves removing the engine)

B8 platform: the actuator motor of the electric parking brake

expensive

A small electric motor built into the rear brake calipers applies the parking brake. This is a known weak point of the B8 platform (A4 B8, A5 8T, Q5 8R, allroad B8): moisture and road salt get into the motor housing, the electronics corrode, and the gears seize. The symptom is a parking brake that will not apply or will not release, with a fault message.

Show the rest

Two things are worth knowing about it. First, the system is sensitive to voltage: a weak battery dropping below 12.2 V can trigger an intermittent parking brake fault on its own, especially in the cold. In that case it is not the brake that needs replacing. Second, servicing the rear brake requires putting the caliper into service mode with a diagnostic tool; forcing the piston back by hand destroys the actuator itself.

above 50,000 km

What to check

  • Apply and release the parking brake several times in a row: it must work evenly and without a fault in both directions
  • Stop the car on a slope on the parking brake alone: it has to hold
  • After switching the ignition on, check for a parking brake or hill hold fault message

Four link aluminium front suspension: bushes and ball joints

expensive

The front suspension of the longitudinal engine Audis (and the Seat Exeo derived from them) works with four control arms per side: two above, two below. That gives excellent steering when new, but it also means four ball joints and eight bushes per side: sixteen wear points at the front in total.

Show the rest

The first complaints appear at around 100,000 to 120,000 km: knocking over bumps, squeaking, vague steering, vibration through the wheel at higher speed, and uneven tyre wear from the disturbed suspension geometry.

Replacing a single arm is not expensive, but it rarely stops at one, and the work also needs a wheel alignment afterwards. Workshops therefore offer a full arm kit, which is a serious item, and an excellent bargaining point, because you can hear it on the test drive and see it on the tyres.

between 100,000 and 120,000 km

What to check

  • On an uneven road at 30 to 50 km/h listen for dull knocking and squeaking from the front
  • Standing still with the engine running, turn the wheel back and forth: there should be no clicking or rattling
  • Look at the inner and outer edges of all four tyres: uneven wear is the surest sign

18V818000FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMPFUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP19 November 2018 · NHTSA (USA)

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2007-2012 Audi Q7 and 2009-2012 Audi Q5 vehicles, previously repaired under NHTSA recall 16V-660. These vehicles were previously repaired with an interim repair of installing butyl tape to the fuel pump flange, until replacement remedy parts became available.

Risk: The butyl tape may not prevent fuel from leaking. A fuel leak in the presence of an ignition source can increase the risk of a fire.

Remedy: Volkswagen will notify owners, and dealers will replace the fuel pump flange and install butyl tape, free of charge. The recall began December 28, 2018. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 20BJ.

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2006-2013 Audi A3, 2007-2009 A4 Cabriolet and S4 Cabriolet, 2008 RS4 Cabriolet, 2009-2012 Q5, and 2010-2012 Audi A5 Cabriolet and S5 Cabriolet vehicles. Upon deployment of the driver's frontal air bag, excessive internal pressure may cause the inflator to explode.

Risk: In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator could explode with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.

Remedy: Audi will notify owners, and dealers will replace the driver's frontal air bag inflator with an alternative inflator, free of charge. The recall began February 23, 2018. Owners may contact Volkswagen customer service at 1-800-253-2834. Volkswagen's number for this recall is 69R6. Note: This recall partially supersedes recall 16V-078.

17V001000VISIBILITY:SUN/MOON ROOF ASSEMBLYVISIBILITY:SUN/MOON ROOF ASSEMBLY3 January 2017 · NHTSA (USA)

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2011-2017 Audi Q5 vehicles. The sunroof drainage system may allow water to soak into the foam surrounding the side head air bag inflator canister resulting in the corrosion of the canister. If this happens, the corrosion can weaken the canister and the inflator could fracture without air bag deployment, propelling fragments into the passenger compartment, striking and causing serious injury to vehicle occupants.

Risk: An inflator rupture may result in metal fragments striking the driver or other occupants resulting in serious injury or death.

Remedy: Audi will notify owners, and dealers will inspect the inflator and either coat it or replace it, as necessary, after removing the surrounding foam, free of charge. The recall is expected to began March 2017. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69P1.

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2009-2012 Audi Q5, and 2007-2012 Audi Q7 vehicles equipped with gasoline engines. The fuel pump flange on the affected vehicles may crack, allowing fuel to leak.

Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.

Remedy: Audi will notify owners, and dealers will inspect the flange, replacing any flanges that are cracked. If the flange is not cracked, dealers will clean the pump flange and install a butyl rubber band to protect the pump. These repairs will be made free of charge. The recall began November 9, 2016. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 20W9.
