Just Sunday I purchased a Silver 1999.5 tdi Jetta with 171K for $2500...two owner car and I have known both owners for years...now for the fun stuff...I know the car needs a timing belt and all associated tune up parts but for now here is my problems: Interior light doesn't work when doors are opened ( yes I checked to make sure light switch was in correct position). I have a blinking glow plug light and a CEL blinking...where do I start...thanks for welcoming me to the family:thumbsup
