my OBDII is report error code P1397, which according to my research is a
Camshaft Position Sensor B (exhaust) fault. Are there any online
instructions
on how to change this? The only one I found was for the E62 engine, not
the
E52. Also, opinions gladly welcomed:
-Should I change both sensors (intake and exhaust) since I'll have
everything
apart?
- Any idea what the dealer is charging to replace the sensor?
