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

Dual mass flywheel: diesel

expensive

The internal springs of the flywheel tire, and the two discs knock against each other. The signs are a rattling or knocking from the bellhousing at idle and when releasing the clutch pedal, and vibration through the floor. If the clutch slips without a burnt smell, that also points to the flywheel. It is worth replacing in time: a disintegrated flywheel can destroy the bellhousing too. At a clutch replacement the two go together anyway.

What to check

  • At idle, without touching the clutch pedal, listen for the rattle from the bellhousing, then press the pedal: if it stops, that is suspect
  • Watch for the characteristic clatter on starting and switching off
  • Put your foot on the floor at idle: a noticeable vibration indicates tired springs

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

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.
