2014 A45 P0339 Crankshaft position sensor error code
My car has become nearly undriveable due to recurring P033900 & P033904 crankshaft sensor faults. Symptoms include jerking, limp mode (~3K RPM limit), engine shutdown while driving, and CEL.
Steps Taken:
- Replaced sensor with OEM part
- Checked wiring/connector – no visible issues
- Checked flywheel no issue
- Sensor installed properly, codes still return
- The issue persists after replacement even getting worse more jerking with engine shutdown.
Thanks
