2 important faults

2.0 / 1.8 TSI (EA888 gen1 to gen2): the timing chain tensioner lets go

critical

With the 2008 EA888 VW switched from a belt to a chain, and the tensioner of the first two generations turned out weak: as the ratchet mechanism ages it does not hold its position when the engine stops and the oil pressure disappears. The oil drains overnight and the chain goes slack. The symptom looks harmless for a long time (a short, few second rattle on a cold start as the chain slaps the guide rail), and then one day it jumps, and the engine is badly damaged inside. From then on the repair is a cylinder head or an engine rebuild. Around 2012 the maker was already fitting an improved tensioner; on the old one only replacement helps, not monitoring the noise.

What to check

  • Start it cold. That is the only moment it is audible: a 1 to 3 second metallic rattle
  • Ask whether the chain tensioner was replaced, and ask for the invoice (the part number is the point)
  • If the seller says it only rattles a little when cold, that is not reassuring but the fault itself

DQ500 (7 speed wet clutch DSG): mechatronics and differential

expensive

The seven speed, wet clutch DQ500 is the DSG of the high torque models (Transporter, Arteon, Tiguan). On a heavy vehicle, on the T5 vans, the splined joint of the differential can shear. Clutch debris blocks the valves of the mechatronics unit, and it jerks on shifts. The pressure sensors fail at around 100,000 to 150,000 km, and then either the even or the odd gears drop out. The control board fails from overheating next to a clogged heat exchanger. It is not repairable, only replaceable.

What to check

  • On the test drive watch for jerking between 1st and 2nd and 2nd and 3rd, cold and warm
  • Pull away gently from standstill: shuddering indicates clutch wear
  • If a whole group of gears (even or odd) is missing, that is a pressure sensor fault

Infotainment that freezes, false warnings

comfort

The most common complaint on the Q3 is the infotainment system: the touchscreen does not respond, dash warnings flicker, the system freezes, or a sensor is faulty. One survey found a fault of this kind on 44 per cent of Q3 cars, and half of the repairs spent more than a week in the workshop. A software update fixes many cases and the update is free, so before you buy, ask whether the latest version is installed.

What to check

  • Leave the system running for the whole test drive and watch for freezing
  • Try the parking sensors and the driver assistance systems
  • Restart the car several times: a fault after a cold start is characteristic

cheap repair1

DSG selector lever: failure of the P position switch

cheap repair

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.
