on 1999 BMW 328is E36 2.8L I6 M52 · RWD

What this code means

The camshaft position does not correlate correctly with the crankshaft position, indicating a timing mismatch. The ECU detects the valve timing is out of the expected range.

  • Check engine light

Common causes

  • Stretched or worn timing chain
  • Faulty VANOS unit
  • Camshaft position sensor fault
  • Slipped timing components

Diagnostic steps

  1. Read camshaft/crankshaft correlation data
  2. Inspect timing chain for stretch
  3. Test VANOS solenoid operation
  4. Verify camshaft timing marks
