Air suspension: compressor, air spring, ride height sensor

expensive

The four groups of parts in the air suspension (compressor, valve block, ride height sensors, air springs) work together, and any weak link causes a fault message, an uneven ride height or a car that settles.

It can affect every car in this generation.

Dual mass flywheel: diesel

expensive

The internal springs of the flywheel tire, and the two discs knock against each other.

Applies to the engine CDSB, CTEC.

FSI direct injection: intake valve coking

expensive

With direct injection the fuel does not wash the intake valves: the petrol goes into the cylinder, not behind the valve.

Applies to the engine CYPA, CAJA, CAKA and 1 more.

4 more faults belong to this generation. On the version page, only the ones that apply stay.

The manufacturer fixes these for free at a franchised dealer. Ask with the VIN whether it was done. The list covers the whole generation. We did not filter it by model year. Some apply only to a narrower production window.

The compression joint between the hydraulic hose and the hydraulic fitting of the power steering can be put under excessive pressure. As a result, oil can leak out in the engine compartment increasing the risk of fire.

A12/01262/20Safety recallFireno date · EU Safety Gate

The wire coil profile used in the radiator tank seal may be deformed due to the very variable temperatures within the engine compartment. Over time, and under unfavourable conditions, this could lead to the radiator seal coming loose. A loose radiator seal could come into contact with hot components in the engine compartment as a result of vibrations during driving. This could lead to the seal and, potentially, neighbouring components starting to smoulder, increasing the risk of fire.

Common questions

About this generation

Which years does this page cover?

2010–2017. The changeover year can fall in two generations. If the listing is from that year, look at the neighbour too.

Does the fault apply to every car like this?

No. It depends on the engine and the transmission too.

Is it free?

The fault list is.

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • 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.
