Another P0018 code
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

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 .
