2 important faults

A thin wall of the mechatronics valve body can crack, which causes a loss of pressure. The typical signs: jerking and harsh shifting from 1st to 2nd at low speed, a flashing PRNDS display, then a gear engagement fault, intermittently at first.

What to check

  • Pull away slowly from standstill and watch the 1 to 2 shift: does it jerk, is it harsh
  • Check whether the PRNDS display flashes or the dash reports a gearbox fault
  • In creep mode (brake released), does the car move off evenly

In the EA211 the water pump and the thermostat are one plastic module, and the pump is driven not by the timing belt but by a separate toothed belt behind the exhaust camshaft. There are usually two problems with it: the plastic housing warps or cracks (slow coolant loss, a sweet smell, rising temperature), or the drive belt ages (a chirping noise, then an engine left with no cooling). The housing is particularly sensitive if oil reaches it: for example from a leaking crankcase ventilation. The module has to be replaced whole: dismantling it warps it in itself.

What to check

  • Check the level in the expansion tank, and ask whether it needs topping up
  • After a cold start smell the engine bay: a sweet smell means coolant
  • Look for dried, whitish pink deposits on the exhaust side of the cylinder head

The powered tailgate of the estate is a common complaint: the lifting motors, the microswitches and the closing mechanism can all fail. The tailgate stops halfway, does not close properly, or opens again on its own.

What to check

  • Open and close the powered tailgate five times in a row
  • Watch whether it stops halfway or opens again
  • Try it from the key and with the gesture under the bumper too, if fitted

The head unit freezes, restarts, or shuts down entirely; the Bluetooth connection drops regularly, and the wireless charger does not recognise the phone. It happens as early as 10,000 to 30,000 km. It is often software, but a hardware fault can be behind it too: the slow response of the navigation and the outdated map are part of the same thing. Cars built up to 2016 still have the first generation (MIB1) head unit, and most of the faults fall on the 2014 to 2016 model years. Intermittent loss of the reversing camera belongs to the same group.

What to check

  • Cycle the ignition three times and check whether the screen comes up every time
  • Pair a phone over Bluetooth and leave it connected for ten minutes during a test drive
  • Try the wireless charger if fitted: does it recognise the phone

cheap repair1

The dash shows "Error: Workshop! Only leave vehicle in position P" with an audible warning. The message appears in whatever language the car is set to, for example "Fehler: Werkstatt! Fahrzeug nur in Stellung P verlassen" in German.

Show the rest

The message points at the gearbox, but the fault is not there. A tiny switch sits in the module under the selector lever and signals that the lever is in park (P). Its contact wears and can also burn. That makes the signal unreliable, and the car warns you. The fault codes appear as 617752, P173400 or B116229.

At first it is intermittent. Sometimes the message comes up, sometimes not, so a short test drive easily misses it. Later it becomes permanent, and the gearbox can drop into limp mode.

This fault looks more expensive than it is. The maker released a separate retrofit switch kit for it (5Q0713128A for the black module, 3Q0713128 for the white one), which can be fitted in half an hour. The kit costs 70 to 100 pounds. At a franchised dealer, however, the whole selector lever module sometimes gets replaced, which costs 626 to 1,000 pounds there. So the difference between the two routes is roughly tenfold.

The affected group is post 2013 MQB platform Volkswagen, Audi, Seat and Skoda cars with a DSG gearbox. The switch is in these gearboxes, because that is what these cars have in common. The part itself is not part of the gearbox but of the module under the lever.

What to check

  • Watch the dash after starting: the message is intermittent and can be missed on a short loop
  • Move the lever from P to D and back several times, then get out and lock the car
  • Ask whether the selector lever switch has been replaced already, and ask for the invoice

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.
