People overthink the vanos.

I replaced my vanos seals with a kit from Beisan systems. This is what I think of fixing them.

Total time maybe 4 to 5 hours.

Easy to do. Yes time consuming and gets messy due to oil spills.

Lots of random tools but other then that I feel like replacing a cv axle is harder to do. Anyone can do a vanos seal replacement. Just need the right tools and on the Beisan web sight they have a very good diy written out use and get what you need ahead of time.

I agree Vanos was a very easy job.

Harder Job would be head gasket or motor overhaul.

I think these are one of the easiest cars I have ever worked on.

Wasn't anywhere near as tough as people state on here and other sites. I just followed the Bayesian diy on my laptop on my work bench and went without a hiccup. The only thing I encountered were totally flat, and hard o-rings that even an Xacto knife wouldn't cut. I just used a sharp dental pick with a 90 degree angle on it to indent the center of the rings with about 3 pokes then I could rotate them out. Be extra careful not to pry against the edges of your vanos piston for any reason because you don't want to mark it at all.

Some people have the knack regardless of age. I know an electronic tech 50 years of age that could not perform the VANOS repair.

I do not recommend this job to those lacking mechanical skills.

VANOS is relatively easy but I think people get scared because the procedure is very long. Or they are just worried about touching anything connected to the valve train.

I think the single vanos you have to lock the cam shaft? But the seals do take a long time but I took my whole day going it and I had lunch and watched a football game

Bad low rpm torque. Look at your vanos timing in inpa to confirm
