Timing for Camshafts (not Vanos)?

[autbahn4410]

The reason I asked is because if you use the correct timing tools and reset the adaptations you should not have a timing code. From experience if you loosen the intake cam sprocket "Vanos ". You can have problems due to the inner seals in the Vanos that are nolonger under tension. Then is oil pressure to adjust the Vanos unit is lost and then the DME does not see the camshaft in the position that it wants.

Well if the VANOS needs to be repaired then the cam sprocket would have to be loosened. I don't think that can be avoided in this case. I would imagine that clearing and resetting adaptations would be beneficial in this case.

If you loosen the intake bolt to set the intake camshaft timing then with out knowing you can cause the problem. That is all that I am saying. Resetting the adaptations does not fix the possible adjusting capability of the Vanos. But what ever floats your boat.
