Engines
A wide variety of engines appeared in the MKV, ranging from the 74bhp 1.4 to the 247bhp R32. VW switched between cambelts and cam chains, so the simplest way to check is by quoting your engine number. Cambelts, where fitted, should be replaced every
60,000 miles, and it’s wise to fit new bolts, tensioners and a water pump at the same time.
It’s a reasonably straightforward DIY job.
For cars with a chain, a little rattle at start-up isn’t uncommon, but if it persists, the chain and tensioners will soon need replacing.
Reliability is pretty good, although engine sensor issues can prove a headache and there have been reports of coil pack issues on petrol Mkvs, possibly as a result of oil ingress, as well as radiator fans failing.
An issue on the 2.0 TFSI engines concerns worn cam followers for the highpressure fuel pump. If a car cuts out for no reason, or the engine check
light is on, it could be on its way out. If it does fail, repairing the damage can be expensive, so many owners now include fitting a cam follower kit as part of the 20,000-mile service. While on the GTI watch for boost leaks – as the cars get older this is becoming more apparent.
The PD diesels are reliable units but if there’s a lack of power or it frequently goes into limp-home mode, a replacement VNT turbo may be required. Bear in mind the PD engines require oil
