Crankshaft Position Sensor Circuit

The DME is not receiving a usable crankshaft position signal. Without it the engine will crank but not start, because the DME cannot time injection or ignition.

Common causes on MINI

Damaged or chafed crankshaft sensor wiring
Failed crankshaft position sensor
Corroded or backed-out connector pins
Reluctor wheel damage
Rarely, an internal DME fault
