190 sun roof leaking!!!!!!!

[jeffn]

Hi all, got a 190 with a leaking sunroof, there is a patch on the headlining where a drip falls onto the rear seat which gets wet, the seal seems visually ok, are there any drain hole which could be blocked and where are they, can anyone please advise, thanks in advance.

There are drain holes at front. they run down the front pillars. check they are clear.

leak...

Mine's the same on my 450slc.
I found that the easiest way to check was to run the sunroof back and then fill the gutter round the sides with water - if if keeps filling then one of your drains is blocked! (you'll see where the water is left and where not)

On mine, it has 4 drains - one on each corner of the roof - my front passenger side is blocked and that's where it leaks.

If you can't get to it immediately - park your car pointing downhill and the water will drain away through the ones that arn't blocked.
