VANOS on INPA
Had my vanos bolts replaced about 6 months ago. It was making a noticeable racket. Fine now, just some rattle at 3200 rpm when the oil is cold. Goes away once the oil is hot. I'll be doing my own valve adjustment for the first time in a couple of months. Will see if that makes any difference.
It took the mechanic that replaced the bolts 2 tries to get the camshaft timing correct(ish). I just got INPA, in German, unfortunately, and got the following. I was able to get enough from Google Translate to know what it says, but I don't know what it means. Looks like the exhaust camshaft is slightly lagging, and the intake vanos setpoint is totally whacked.
This was idling in the garage with no load. Revving the engine didn't change much. Maybe it's supposed to look like this with no load?
