2011 Audi A8L
my issue started after I made a mistake and overfill the motor with oil .
The light came up as I was 60 miles away from home and the car started to drive poorly .
When I returned home , I drained and refilled with the right amount , I had to change all coils and clean the coil tumels as they were all soaked .
The car started running better but the check engine light stays on .
I scanned it and get the p0018 code crankshaft sensor.
The car takes a free runs to start , about 2-4 seconds but runs fine . If I clear the code , it starts fine and the check engine light will stay off until I turn it off and crank it again. .

After reading some threads here and other forrums , I replaced both camshaft sensors on top of the engine and removed all four VVT's pulse them with 12 volts to make sure they were not stuck with oil crumbs . Still the same .

I don't know what else to do , your input is appreciated

uhm confused why are you replacing the camshaft sensors when the fault code is crankshaft sensor? Would it not make more sense to replace the crankshaft sensor which as far as I remember the crank is at the bottom of the engine?

Thanks for your reply .
I read some threads that pointed out to the camshaft and vvt.
in addition , the P0018 refers to bank a does not correlate to bank b.
If there is only one crankshaft sensor according to the available material on this topic that I've read ,how does it correlate?
I still can't find any thread that would point me to the location of the crankshaft .

This is the D2 forum, by 2011 do you still have the 4.2 with belt driven cams?

I am not sure . This is a question that someone here may be able to answer.

Probably not. Your 2011 would be on the D4 forum
