It almost sounds like you have an issue with your Oil Pressure Accumulator. Have you noticed an increase in sound within your vanos units?
Part #13.

It is an 03 and I don't see an electrical connector.Which model year is your M5?
Do you have an electrical connector on the pressure accumulator?
cool....will you be around this weekend? I have your part as well.you have the unit they are talking about on your car.
swing by if you want to try my spare unit.
thanks...Give tradin's unit a try...
I would also check if the wiring is ok...
Thanks again tradin1...you have the unit they are talking about on your car.

wiring looked fine, didnt actually check for continuity though.Check the wiring,have seen them sometimes break as well.
Also,disconnect it,clear the codes and see if the same error code comes instantly back...
Also disconnected threw the same code?wiring looked fine, didnt actually check for continuity though.
the code was instant, even after resets.
No change recently. I had Dinan stage 4 done back in April 2010. We did not disconnect it then check for codes, so I'll try that next.Also disconnected threw the same code?
The brown black wire should be ground,the red-violet one goes into the ECU,module 2,pin 8...
So check ground and the wire from the ECU...
Was lately the ECU software changed?
I think what Raiku is getting at, is if you disconnect the wiring/plug and get only the same code, you can definately say its part of the accumulator system/wiring.
If you disconnect and get 2 codes on a restart then that would point at something else which is the issue, as the "new" code would be because of the accumulator not working/being connected
