Question Power steering fluid spill over
I was driving on a gravel road, with the suspension raised. A few feet before reaching the pavement I lowered the suspension. Next stop light I see smoke coming on the right front fender. Power steering fluid had spewed out of the reservoir. I am almost certain this happened when I lowered the suspension. A few months back I saw a little puddle of oil in the garage by the front right tire. I could see that it was dripping from the reservoir, cleaned everything and couldn’t find any leaks. Now I think it was the same thing with the suspension. Has anyone had the same experience or know about it?

Sounds like your diagnosis is on the right track.

I believe W166 does not have any steering fluid. It is an electronic system.

No PS fluid on the w166's. You're looking at a reservoir for something else.

So is this fluid for the suspension only?
