DQ250 (6 speed wet DSG): mechatronics and clutch pack

expensive

The solenoids of the mechatronics unit wear out: slow or harsh shifting, then limp mode. A characteristic sign is the partial or complete loss of reverse. Wear of the clutch pack or the wrong spring force causes jerking and slipping. Because of the wet design it fails less often and at higher mileage than the dry DQ200, but when it does fail, it is expensive.

above 150,000 km

What to check

  • Pull away slowly from standstill and watch how smooth the 1 to 2 and 2 to 3 shifts are
  • Select reverse several times, cold and warm: is it delayed, does it engage at all
  • Under load (on a slope) watch whether the clutch slips

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. The oil mist and soot arriving through the EGR and the crankcase ventilation therefore build up on the valve stem and head, and from 80,000 to 100,000 km they restrict the flow. Symptoms are hesitation, loss of power, a rough cold start and misfire. It is not a part failure: it is a consequence of the design, and therefore it comes back. Cleaning (walnut or dry ice blasting) helps for a few tens of thousands of kilometres.

What to check

  • After a cold start watch the idle: rough running and shaking point to coked valves
  • Under load at low revs watch for hesitation
  • With a code reader look for per cylinder misfire (P0300 to P0304)

I: suspension, springs and dampers wear above average

expensive

The CC does worse in the roadworthiness test statistics than the saloon or estate Passat built on the same base, and it does so at lower mileage, for a reason the reports do not explain either. The failures are led by the wheel suspension, the springs and the dampers. Above five years of age the picture gets noticeably worse: that is when the driveshaft faults arrive, and the engine management and emissions checks also fail more often than average. On top of that the ADAC reports faults around the fuel pump, the injectors, the rear wheel brake cylinder and the turbo. An important model year line: the figures for cars built from 2011 onwards are already significantly better.

What to check

  • On an uneven road with the window open, listen for knocking from all four corners
  • Shine a light on the damper rods: an oily film means a leak
  • Push the car down at each corner: several rebounds mean a tired damper

Coolant temperature sensor (G62) failure

comfort

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

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

VOLKSWAGEN IS RECALLING CERTAIN MODEL YEAR 2012, CC VEHICLES, FOR FAILING TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLES SAFETY STANDARD NO. 138, "TIRE PRESSURE MONITORING SYSTEM (TPMS)." THE FACTORY INSTALLED WHEELS AND TIRES WERE REPLACED AT THE PORT WITH ACCESSORY WHEELS AND TIRES THAT WERE NOT EQUIPPED WITH THE PROPER TPMS SENSORS.

Risk: WITH THE INCORRECT TPMS SENSORS, DRIVERS WILL RECEIVE A CONSTANT WARNING FROM THE TIRE PRESSURE MONITOR SYSTEM. THE SYSTEM ALERTS THE DRIVER BUT, DUE TO INCORRECT TPMS SENSORS, THE SYSTEM CANNOT DETERMINE IF THE VEHICLE TIRES ARE PROPERLY INFLATED. THIS INCREASES THE RISK THAT THE VEHICLE WILL BE DRIVEN WITH ONE OR MORE UNDERINFLATED TIRES, INCREASING THE RISK OF A TIRE FAILURE THAT MAY LEAD TO A CRASH.

Remedy: VOLKSWAGEN WILL REPLACE THE TPMS SENSORS WITH THE PROPER SENSORS TO MAKE THE TPMS SYSTEM OF THE VEHICLES COMPLIANT WITH FMVSS 138. AS OF JUNE 1, 2011, VOLKSWAGEN HAS CONTACTED ALL AFFECTED CUSTOMERS TO SCHEDULE THE REPAIRS FREE OF CHARGE. OWNERS MAY CONTACT VOLKSWAGEN AT 1-800-822-8987.

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.
