A rattling sound began to come from the engine compartment shortly after passing 85,000 miles on the vehicle. Scanned the computer and found several codes for misfires and vacuum leaks on the vehicle ecu. Took it to a shop after performing routine maintenance did nothing to smooth out engine operation. Shop shortly contacted me back with a quote of the timing chains were coming apart and the engine was severely out of time. After some research online this appears to be an issue with the early 2.5l mk5 jetta engine.

This vehicle is a 2006 turbo diesel vw jetta. I was driving on the highway when engine failed, no warning lights. Experienced loss of power, rough idling, valve train noise and transmission noise. Had vehicle towed to certified mechanic. Mechanic found complete loss of compression on one piston and scored lifters. Also dual mass flywheel was making loud noise and needs to be replaced. Volkswagen dealership quoted est 1800 dollars for parts and labor for flywheel and certified mechanic recommends rebuilt engine for appx 5000 dollars plus labor to install. Estimate will be complete next week. Total will est around 9 to 10,000 dollars for towing, inspecting vehicle to find issues, parts and labor. Spoke with volkswagen of america consumer advocate who offered us $750 off a new vw. This vehicle has been well cared for with appropriate oil changes using vw approved oil. Most of the mileage was obtained as highway miles.

The engine in our 2006 tdi dsg began to exhibit rough idling. At a certain point it became evident something was wrong. The vehicle has always been serviced by a vw dealership at the specified intervals (I call them the $400 oil changes). I could hear what sounded like an intake valve popping and could feel a pulsation in the turbo intake hose. I checked on some of the forums and was shocked to learn of the early camshaft failure problem common to the pd engines. It seems that vw narrowed up the intake and exhaust cam lobes by about 30% to make room for the injector lobe, and tried to compensate for this inadequate design by mandating "special" oil (which I can only hope our dealer used each time the oil was changed). It turns out though, that a critical can wear additive in this oil, zddp, in sufficient quantities can cause early failure of the catalytic converter (an item which has a longer warranty period than the engine). It seems that the zddp only exists in sufficient quantity in vw "special" oil to get through the engine warranty period, while at the same time protecting the converter from warranty failure. I bought an after market cam kit and installed it myself, saving nearly $3000 in the process. Since then we've put another 60k miles, using mobil td truck 5w40 oil... So far so good. I think this whole situation is disgraceful at best and vw should be responsible for all pd camshaft failures to a period significantly longer than the 80,000 km warranty. The primary reason we paid 32k for a compact sedan was the reputed longevity of the diesel engine. This failure, along with the dual mass flywheel fiasco has made our purchase of this silver colored lemon anything but a good investment. Until vw faces up to their moral responsibilities in this matter I would caution anyone considering this make of vehicle.

Noticed very rough idle. Dealer diagnosed manual transmission flywheel malfunctioning without visual inspection. The fault was placed with me. Wear and tear. Dealer claimed must fix, not safe to drive, quoted $2100. If this problem is allowed to worsen, the failure mode is a complete clutch failure and on a busy freeway is a serious safety issue. I went to a third party garage and paid $1200 for a more reliable single mass flywheel. The damaged sachs dmf is available for inspection.
