“PASSENGER SEAT OCCUPANCY SENSOR IS HAVING ERRORS. SHOWING A PASSENGER WHEN NONE IS PRESENT AND ALSO SHOWING NO PASSENGER WHEN THERE IS ONE IN THE SEAT. THIS IS A PRETTY MAJOR SAFETY ISSUE.”
“Prior to August 2024, this vehicle operated with zero check engine lights or drivetrain faults. In August 2024, BMW of Pittsburgh executed federally mandated Safety Recall 23V-707, which required opening the cylinder head. Immediately following this service, the Check Engine Light began illuminating persistently.On or about October 3, 2024, an independent diagnostic scan at Bobby Rahal BMW pulled BMW Factory Code 002A89: Exhaust VANOS Camshaft Mechanism Fault (Mechanical Sticking/Flow Restriction). Technicians at Bobby Rahal BMW explicitly instructed me to return the car to BMW of Pittsburgh because they suspected the original VANOS safety recall repair was botched.On October 28, 2024, I returned the vehicle to BMW of Pittsburgh to address this issue.

Within approximately 24–48 hours of picking up the vehicle, the check engine light illuminated and the vehicle began operating abnormally, including rough idle and irregular shifting. The vehicle stored diagnostic fault code P054B (camshaft position timing over-retarded), which directly relates to camshaft timing and the VANOS system involved in the recall repair. I returned the vehicle to the dealership for further diagnosis. The dealership stated an aftermarket camshaft position sensor with two O-rings was installed and removed one O-ring to correct the gap between the sensor and the camshaft reluctor wheel. The faults were cleared and the vehicle was returned to me. However, the check engine light returned again the following morning upon cold start, indicating the issue was not corrected. My service advisor has since stated that replacing the camshaft position sensor is not part of the recall repair and the dealership has…”
