I rebuilt my vanos with the Beisan kit including the rattle kit and my significant 2500-3000 stumble has not gone away. Are there any other issues that closely mimic the vanos symptoms? The vanos seals were definitely worn when I replaced them.

You went through the 200 city mile break in period, correct?

Has your ZHP received the shipped-off-to-New-Jersey DME update/reprogram? I think that's usually for a "power dip" around 3.8—4 k, but perhaps?

Did you verify that the Vanos pistons moved inside of the cylinder as they are supposed to before you buttoned her back up?

You probably need the software updated to the latest version. This can be done at any dealer or good indy. This is different than the one Crickett mentions that requires the DME to be sent to Jersey. I had the same issue, a miss under acceleration in the higher gears....rebuilt the vanos first and it made no difference. Had the s/w updated and it is completely gone.
This is assuming you've already changed spark plugs, fuel and air filters.

Could a bad DISA valve be the culprit?

Switch over is at higher RPMs, so I would think not, but someone might have a better take on it.Originally Posted by JohnnyGraphic

I definitely felt an increase in performance after replacing the vanos seals, but I still have the stumble. Plugs and all filters have been changed. How much is an update going to cost me? Everything looked good when i put the vanos back together, but I suppose anything is possible. I'll get an update at a dealership and if that doesn't solve it I'll tear the vanos back down...

A DME update should only cost you an hour or two of shop time; they just plug it into the GT1 & run the update (I believe).
