I took the car to the dealer and they said it was something the camshaft sensor and it was replaced, but the grinding was going on and they basically said at this point to not worry about.
The check engine light came on last weekend and I took my car to the dealer and they suspected that there was a problem with the timing chain.
How much should it cost to have the timing chain replaced?
This doesn't directly answer your question, but find a new dealer. My old audi dealer was like that too, everything came back "could not duplicate" and then they would charge me a diagnostics fee. Or they would have me replace two to three parts before the switched. For example to fix my auto up down drivers window. Replaced the door pad, and even the regulator or something. BTW its still broken. Really find a new dealer.
