Product Title
BMW B38 B48 Crankshaft Position Sensor Crank Angle Sensor – Original Used Part
Diagnosis and Common Symptoms
The crankshaft position sensor is the primary timing reference for the DME (Engine Control Unit). On the B38 and B48 modular engines, a failing sensor typically manifests as an intermittent signal loss once the engine reaches operating temperature. Common fault codes include P0335 or BMW-specific codes related to crankshaft signal plausibility. Symptoms include prolonged cranking before the engine starts, sudden stalling while idling or decelerating, and a "Drivetrain Malfunction" warning on the iDrive screen. In severe cases, the engine will crank but fail to fire because the DME cannot synchronize fuel injection and ignition timing without a valid crank angle signal.
Introduction
As a technician, I recommend Genuine BMW sensors over aftermarket alternatives because the B-series engines are highly sensitive to signal frequency and voltage drift. This Genuine Used unit has been salvaged from a low-mileage donor vehicle and subjected to a multi-point inspection to ensure the magnetic tip and electrical connector are free from degradation. By choosing a tested Genuine part, you ensure factory-spec timing accuracy without the high cost of a brand-new component.

Frequently Asked Questions
Q: What symptoms indicate failure? A: The most frequent signs are engine stalling when hot, difficulty starting (long crank), and erratic RPM needle movement. If your BMW cuts power unexpectedly and then restarts after cooling down, the crank sensor is the likely culprit.
Q: Does this require coding? A: No, this is a hardware-based sensor and does not require software coding or VIN registration. However, it is highly recommended to clear the stored fault codes in the DME after installation to take the vehicle out of emergency "limp" mode.
Q: Is this original? A: Yes, this is a Genuine BMW factory part. It carries the original manufacturer markings, ensuring it meets the exact electrical resistance and signal output requirements of your B38 or B48 engine.
