3 important faults

critical1

1.2 / 1.4 TSI (EA111): timing chain and chain tensioner

critical

A few seconds of chain rattle on a cold start, later a permanent noise; the chain stretches and the tensioner does not hold it. If the chain jumps, the engine is badly damaged inside, and the repair is a rebuild. The tensioner is driven by oil pressure, so it does not hold with the engine stopped: a car left rolling in gear is the typical trigger for the chain jumping.

between 65,000 and 100,000 km

What to check

  • Start it cold, and in the first 2 to 3 seconds watch for the rattle from the chain side
  • Ask whether the chain and the tensioner have been replaced, and ask for the invoice
  • Check the oil change history in the service book: stretched intervals speed up the wear

MQ200 / MQ250 manual gearbox: differential bearing and synchros

expensive

The light, magnesium cased MQ200 and the MQ250, sized for higher torque, are the most widespread manual gearboxes in the transverse engine VAG models. Both have the same two weak points, and both depend on use.

Show the rest

The first is the differential bearing: as it wears you first get a droning, then a whine from the thrust bearings of the output shaft. Left alone, the planetary shaft can fail and in extreme cases punch through the gearbox casing: from then on it is not a repair but a replacement.

The second is the synchros: they can start crunching at around 50,000 km with aggressive driving. This type does not like dumping the clutch or slipping it, and on a used car that is exactly what you have to listen for.

above 50,000 km

What to check

  • On the test drive with the window down, listen to the gearbox both off and on the throttle: droning or whining is suspect
  • Shift up and down quickly, especially into 2nd and 3rd: crunching means synchro wear
  • Try engaging 1st and reverse when cold: resistance here means wear

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)

19V615000ELECTRICAL SYSTEM:IGNITION:ANTI-THEFT:CONTROL MODULEELECTRICAL SYSTEM:IGNITION:ANTI-THEFT:CONTROL MODULE22 August 2019 · NHTSA (USA)

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2015-2019 GTI, 2015-2016 and 2018-2019 Golf, 2012-2019 Beetle and Beetle Convertible, 2017-2019 Golf SportWagen and 2011-2018 Jetta vehicles equipped with an automatic transmission, manual handbrake and keyless entry. A build-up of silicate on the shift lever micro switch contacts may enable the key to be removed from the ignition when the transmission shift lever is not in "Park."

Risk: Removing the key while the shift lever is in a position other than "Park" increases the risk of an unintended vehicle rollaway that may result in personal injury or a crash.

Remedy: Volkswagen will notify owners, and dealers will install an additional switch and circuit board, free of charge. The recall began November 19, 2019. Owners may contact Volkswagen customer service at 1-800-893-5298. Volkswagen's number for this recall is 37M2.

14V656000SUSPENSION:REARSUSPENSION:REAR20 October 2014 · NHTSA (USA)

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2011-2013 Jetta vehicles manufactured March 1, 2010, to November 30, 2012, and 2012-2013 Beetle vehicles manufactured March 1, 2011, to July 31, 2013. The durability of the rear trailing arms may be reduced in vehicles whose rear trailing arms have been previously deformed, such as a result of a rear or side-rear impact crash.

Risk: The reduced durability of the trailing arm may result in its sudden fracture, possibly causing loss of vehicle control and increasing the risk of a crash.

Remedy: Volkswagen will notify owners, and dealers will install a sheet metal inlay on the rear axle trailing arms designed to prevent a sudden loss of control in the event of trailing arm sudden fracture, free of charge. The recall began April 7, 2015. Owners may contact Volkswagen customer service at 1-800-893-5298.

THE FUEL INJECTION PULSES COULD COINCIDE WITH THE NATURAL FREQUENCY OF THE INJECTOR LINE #2, IN SPECIFIC LOAD AND RPM CONDITIONS. THIS RESONANCE CREATES ADDITIONAL STRESS IN THE FUEL LINE.

Risk: DUE TO THE RESONANCE CONDITION, INJECTOR LINE NUMBER 2 COULD DEVELOP SMALL CRACKS WHICH COULD LEAD TO FUEL LEAKAGE. LEAKING FUEL IN THE PRESENCE OF AN IGNITION SOURCE, MAY LEAD TO A FIRE.

Remedy: VOLKSWAGEN WILL INSTALL AN IMPROVED FUEL INJECTOR LINE FOR THE NUMBER 2 CYLINDER ON CERTAIN VEHICLES AND WILL INSTALL VIBRATION DAMPERS ON ALL OF THE INJECTOR LINES. VOLKSWAGEN AND AUDI WILL NOTIFY OWNERS TO HAVE THE VEHICLES REPAIRED FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING NOVEMBER 2011. OWNERS MAY CONTACT VOLKSWAGEN AT 1-800-822-8987.

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.
