1 important faults

expensive1

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

comfort2

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
2 more steps in the write-up

From the late nineties to around 2006, petrol engines used a secondary air pump to blow fresh air into the exhaust on a cold start, so the catalytic converter reaches operating temperature faster. The impeller of the pump rusts or its bearing seizes, soot clogs the combination valve (N112), and the rubber hoses crack. The control unit then stores the `P0411` code. It barely affects driving, but the engine warning light is on, and the emissions test can fail because of it, and the roadworthiness test with it.

What to check

  • After a cold start watch for 30 to 60 seconds: can you hear the pump droning from the engine bay
  • Check whether the engine warning light is on, and have it read out: P0411 (VAG code 16795) points to this system
  • Ask when the last emissions test was, and whether it passed first time

The airbag may deteriorate over time and if deployed, excessive internal pressure may cause the inflator body to burst and metal fragments could pass through the cushion material causing injury to occupants. The product does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.

A12/00884/21Safety recallInjuriesno date · EU Safety Gate

The propellant used in the airbag inflator of the passenger airbags, manufactured by Takata, may experience a material alteration over time due to degradation occurring after prolonged exposure to high absolute humidity and high-temperature cycling. In the event of an airbag being deployed, the excessive internal pressure may cause the inflator body to rupture and metal fragments may pass through the cushion material causing injury to the occupants.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
