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

Water gets in through the sunroof drains, the door seals or the window guides, and collects on the floor and in the sill. The water also ruins the wiring and the control units in the floor, which leads to hesitant starting and an alarm going off on its own. With a fault like this, lift the carpet first, because the water is under it.

What to check

  • Lift the carpet in all four footwells and press the felt with your palm
  • On a car with a sunroof, open the roof and look at the drain openings in the corners of the frame
  • Pour water carefully over the sunroof frame, and see where it drains

Pixels drop out on the central display of the instrument cluster, where you read the trip computer: the text fades, the backlight becomes erratic, at first one or two dots are missing, and later whole lines are unreadable. This is where the service interval, the outside temperature and the warnings appear, and if a warning is unreadable you will not notice it. The instrument cluster can be refurbished, and a new one is not always needed.

What to check

  • After switching the ignition on, go over the whole display: a missing dot, a line, a faded section
  • Page through the trip computer menus: the fault often only shows on certain readouts
  • In the dark or in a garage, check that the backlight is even

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

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

cheap repair3

On the 8P the rubber bushes in the front lower control arms wear out: the steering goes vague, you hear a knock on uneven roads, and the tyre edges wear unevenly. It often shows up around 60,000 to 80,000 miles, which is roughly 95,000 to 130,000 km. On front wheel drive cars the rear suspension bushes wear too, it then rattles, and the back of the car follows the front uncertainly. One part on its own is not expensive, but when they all need replacing together the suspension repair costs more. You can hear it on the test drive and see it in the tyre wear.

between 95,000 and 130,000 km

What to check

  • On an uneven road at 30 to 50 km/h listen for a dull knock 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 points to worn bushes

The central locking control unit takes in moisture over the years, and from then on it is unpredictable: the doors do not lock together, the remote sometimes does not respond, and the alarm goes off for no reason. A door that stays open is a problem in a car park, and an alarm that goes off on its own can flatten the battery.

What to check

  • Lock and unlock with the remote several times, from different distances
  • Check whether every door locks together and fully: the tailgate too
  • Try the driver's lock with the key blade as well

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

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.
