I can only find something for the E46 M52TU, DME fault code 67/68 - VANOS end position regulation,
Complaint: Whenever a camshaft pulse generator (inlet or exhaust) is renewed, the engine will enter emergency running mode, i.e. the engine will run with reduced torque and output.
The following fault codes are stored in the DME fault memory:
