problem #1

A4 4-cyl

  • Manual transmission
  • 53,500 miles
Malfuntion indicator had been on before I deployed to iraq and was still on when I came back. I brought it to the dealor for the $50,000 mile scheduled maint. Less than 2 months later, I started the car at a store and heard a loud pop, the engine started idling hard and was very noisy. I was able to drive in first gear the two blocks to my house but the car was very shaky. The spark plug had shot out, there was oil and grime all over it and the threads of the cylinder were stripped. My friend in the car, who has worked on porshes before, said I was lucky this happened when it did because if I was driving on the highway at a high speed, I probably would have been seriously hurt in an accident. The cost of repair is estimated at $5100 and the dealor said that there was no tampering with the spark plugs for almost a year so this "just happened" due to "wear and tear." The car is 3 years old and most the miles are highway miles due to several trips cross country. I am nervous to think what will go wrong when the car gets a little older.
