 At approximately 60,000 miles, the engine started missing and the Check Engine Light (CEL) came on.  Dealer told me that it was "due to a problem with the fuel injection system, the valves become coated with carbon causing the misfires."  Cost to clean the valves was $600.00 plus tax.  At approximately 92,000 miles, the car overheated and had to be towed in.  Dealer found the thermostat had failed.  Unfortunately, the thermostat is built into the water pump and the entire unit had to be replaced.  That bill was just under $1,300.00 plus towing and three days of car rental.  At 122,000 miles the CEL came on and the misfires started again.  While driving to the dealer, the EPC light came on.  Dealer reported that not only did the valves need cleaning but that the "shaft pulls out of intake manifold for the intake flap".  That's exactly what they wrote on the service description, just jibberish".  Whatever it meant, it required a new intake manifold.  The entire bill was $1,360.00 plus two days of car rental.  Picked up the car and drove off the lot when the CEL started flashing and the car stalled.  Limped it back to the Dealer.  Dealer called the next day to report that the spark plugs and ignition coils needed to be replaced.  Cost $365.00.  When I told the rep that the plugs had just been replaced, I was told that sometimes spark plugs fail earlier than they should.  I requested that they replace the coil and the spark plug for the cylinder with the misfire so that I could limp it off the lot to the nearest Honda dealer for a trade-in.  My last two cars were Hondas and I drove both of them right up to 250,000 miles without a single failure in either car.   I'll never buy another VW.  For the record, I found out that not only do the valves need regular cleaning but the rear seals frequently fail on these engines so watch for that expense as well.
