P0016 on BMW – Crank/Cam Correlation

BMW notes for P0016. Correlation faults should be diagnosed carefully before replacing parts.

What P0016 Usually Means

  • Sensor signal plausibility issue (cam/crank sensor, wiring).
  • Mechanical timing deviation (chain stretch, timing component wear).
  • Less commonly, a software adaptation issue after work.

Suggested Safe Test Plan

  1. Check for related codes and review freeze-frame data.
  2. Inspect wiring/connectors for cam and crank sensors.
  3. If symptoms are severe (rattles, poor starting), avoid hard driving until timing is confirmed.
  4. Confirm timing plausibility with manufacturer-level data where possible.
