Hello Everyone,
this is my 1st time posting on here. Hoping to find some answers. it's been a couple of weeks now and I still can't figure it out.

Sooooo... i just bought and A4 B6 a.8T with 235000km on it. Everything was great until it started to have a hard time to start. Engine cranks but doesn't start. after a few tries it will actually start. So I plugged in my scanner it shows me P0343 Crankshaft position sensor.
I replaced the sensor itself and cleaned the area. The code is still there even after reseting ECM. I checked if there is power in the harness and it gives me the 5v.

Does that mean my ecm needs to be replaced? Is it just an electrical problem or it could be related to something else.


Thank you for your help.
