I have searched the forum's many threads on this topic but can't quite find answer to this. Mine is an SLK 230 (1999). The headlight 'light range' adjustment is not working. I know that this is vacuum driven and like other models I assume other functions are too. I am not aware of any other functionality failings ie. central locking etc is working fine. However..........
With the engine running, if I disconnect the lilac vacuum pipes from the headlights there is no hiss or air being pumped out of them. So far as I can see all the pipes are still joined and undamaged.
This was present a few weeks ago when I mistakenly disconnected one of the headlight connectors when I was doing some work on the headlights. When I started the engine at that time there was an audible hissing ensuing from the disconnected pipe (which I reconnected). Now, as I say, there's nothing.
My guess is that the cause may be the valve (as opposed to the control switch) and having referred to the 'russian' diagram I can see that this is part number 0011406660. However (and this may seem daft) I need to know for sure whether the offending valve is the one that sits above the manifold on top of and at the left hand end of a metal 'pipe-like' component. It is held in a recess by a circlip with a diameter of about 1.4 inches.
Any guidance will be appreciated please. And if the valve is the one I have described, how is it removed and fitted? Is it a case of removing the circlip and pulling the valve out or are there other subtleties to the job?
Best regards and thanks in anticipation - Steve
