Hey Lads,

Getting set here soon to pull the vanos off my X5 and replace the seals. I have been suffering with running issues which I believe all back up to the vanos unit.

Just wondering, I have seen a lot of vids and writeups on the process annd I am fine with it. Just looking for any gotchas that others may have experienced?

Also,
Is it necessary to put the motor at TDC?
I haven't seen it mentioned anywhere but I want to be sure. When I get to replacing the vanos, is there anything that needs to be placed, calibrated, etc?

TIA
Bernie
