Running well but engine MIL illuminated.

Three previous shops had a look at this fault, with no success.

Confirmed that engine MIL was remaining on when vehicle presented, with no running issues.

Fault code present:
- P0018 - Crankshaft position - Camshaft position Correlation Bank 2 sensor A
Pending code logged within one minute after start-up, viewed in OBD2.

Found the actual fault was a mechanical issue caused by incorrect positioning of sensor ring on the body of the VVT, causing incorrect feedback.
