I just had four different dealers look at my car about a lack of power and and funny noises. They all said that my car has engine sludge and that I will need a replacement engine. They could flush it, but then I would have to change the oil every 1000 miles. i am at my ropes end with this car, it is always something new that breaks with the car. Please do not get me wrong, I love my car, it rides great, excellent features.....but the money I have been having to spend is killing me. I think I will be getting rid of the car soon and be looking for something new. If I stay with VW is still up in the air. I may be looking at a diff car make. I will be getting estimates on a new engin starting tommorow, I will let you all know. If anyone knows how the hell I got engine sludge, please tell me. I change the oil every 3000-3500 miles, new air filter every six months, and keep up mantaince on the car religiously.
