Congrats. I am getting ready to do this in a few weeks. My VCG leaks badly and I want to do the both (VCG and Vanos) at the same time. I am going to use Beisan seals as well.
After replacing the Vanos seals, have you experienced any hickups or weirdness during the first few hours/100 miles etc?
I heard that it would take a while for the seals to get broken in properly and make the car run smooth.
I even read one post where the owner was experiencing severe idle hesitation after the Vanos seal replacement. I wonder if this is typical.
