5 important faults

critical1

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)

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

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

The internal springs of the flywheel tire, and the two discs knock against each other. The signs are a rattling or knocking from the bellhousing at idle and when releasing the clutch pedal, and vibration through the floor. If the clutch slips without a burnt smell, that also points to the flywheel. It is worth replacing in time: a disintegrated flywheel can destroy the bellhousing too. At a clutch replacement the two go together anyway.

What to check

  • At idle, without touching the clutch pedal, listen for the rattle from the bellhousing, then press the pedal: if it stops, that is suspect
  • Watch for the characteristic clatter on starting and switching off
  • Put your foot on the floor at idle: a noticeable vibration indicates tired springs

The vanes of the variable geometry turbo are glued together by soot and oil arriving through the EGR. First you get overboost or a lack of boost, then loss of power above 2,000 rpm, and finally limp mode. Caught in time it is enough to remove the turbo, clean it and fit a new actuator rod. Short urban trips and gentle, low rev driving speed up the deposits.

What to check

  • On the motorway, load it above 2,000 rpm: does it pull evenly, or does the power break up
  • Watch whether the warning light flashes up under acceleration (overboost protection)
  • Ask what kind of journeys it did: a daily short urban run is the worst

comfort1

The G62 sensor tells the engine control unit how hot the coolant is. If it is faulty, the control unit thinks a warm engine is cold, and runs it rich: hard warm or cold starting, a rough idle, markedly increased fuel consumption, and a dash temperature gauge that jumps around or never reaches its usual reading. The part is cheap and can be replaced in half an hour: the trouble is that many people do not recognise it and replace an injector or a lambda sensor instead. If the fault persists, the rich mixture can destroy the catalytic converter too.

What to check

  • Warm it up and watch the dash temperature gauge: the needle should sit steadily at the middle reading, not jump around
  • Watch a cold start, then a warm start after twenty minutes standing
  • With a code reader look for the 17664 / P1256 code in the engine control unit
