Hi everyone,

Yesterday I pulled out my vanos solenoids for some maintanance cleaning, without having any specific codes. They both have some rust on them and I was wondering what is the cause of this. Does it have any negative effect, should I change them?
I am actually chasing an intermitent rough idle, which does not trigger any cause. Looking at the location of the rust, I can't see this having an effect, but I'd like to know your opinion on the matter. More importantly I am wondering why this happens in the first place and if there is something wrong with my engine.

Reinstall them and move on with your life.

Well, you might as well clean them with some solvent and compressed air since you have them out.
