#1 Glow plug 
186000 mi

US $3500
Car (it’s a diesel) experienced a brief “runaway” while I was driving the kids to school, where it redlined and wouldn’t stop until I shut off the engine, after which it started smoking, and check engine light came on. The car drove, but was dropped off at dealer soon after. Dealer diagnosed a cracked glow plug harness, which was not connecting to Cylinder 3 properly. That fix ran $700. Dealer also recommended replacing gaskets, springs, etc. – for a total of “$4,000, but discounted to $3,500”. This was all about half a year or a year after the dealer installed a brand new intake manifold ($1,100 total or thereabout). I wanted the car to last another year or so, so I figured it would be cheaper to fix the little devil I knew, than spend on a devil I didn’t, so I agreed. A week later the engine experienced another runaway, but this time even shutting it off didn’t stop it. It blew a ton of smoke out the tailpipe and stopped. Knowledgeable people tell me that the symptoms suggest oil in the intercooler was the culprit, where the turbo would blow that into the combustion chamber, supplying fuel even if the normal fuel line was shut off. I’m baffled that the dealer didn’t pursue this and check for oil in the IC. At any rate, the car is dead now, I’m out more than $4,500 in repairs in about a year... Love the design of the TDI Wagon, want to get another one for its functional features, not loving the crap VW reliability. For a car produced in such large numbers, for so many years, you’d think they would figure this stuff out...
