Last night our '02 300M was difficult to start, and when it did start the Check Engine light was on.
The error codes were:
P0340 camshaft position sensor error P0335 crankshaft position sensor error
I have an appointment to take the car to the dealer in the morning (have to leave it all day), and they say that I could be up for $70 diagnosis work before anything else can be decided.
What is the possible cause, and how much could it end up costing?
