Markus,

You are right age and miles might have a lot to do with it.

But what else would be so much fun to drive everyday and watch

People's neck break when you slide by.

Only comes in when raining hard and car is sitting....



Hm...with over 500K miles, I find it hard to believe that beast sits
much! :)



Can't help you with the rain...you might need to move to LV or the like
where I think Mike Ramay said (at least as of August) it hadn't rained
yet this year! Ha ha!

Marcus,
I have a new front window. It was put in very carefully, as I
told
the repair company it could be leaking into the car. THERE IS NO
WATER
COMING FROM ANY PART OF THE FRONT END. It only comes in when
raining
hard and car sitting.

Hi there,

I had a similar problem with my 380 SEC although it was on the
passenger side rear.

I did the following:

~ Cleaned all the drains in the scuttle at the base of the
windscreen.
~ Checked all sunroof tubes and blew air through them to ensure
they were clear.
~ Checked the aircon drain.
~ Checked every other damn thing I could check.

In the end, the problem 'went away' after I replaced the front
windscreen.

I think in resealing the windscreen, they did a better job than
previously. They spent time getting rid of any sharp areas around the
window frame and that made the difference I believe.

One factor to look out for is water slipping in under the chrome
surround and gradually penetrating into the car. In my case, I think I
had a couple of very small tears in the rubber and the water was able to
make its way in there under pr essure, especially when driving in the
rain. There are a few sharp points on the window moulding that can make
enough of a hole to allow moisture in.

The seals on a Mercedes need very careful installation and I
think it's easy to get it wrong. I'm sure an older, experienced W126
mechanic would be able to relate tales of how many times they took to
get it right.

I used to have a Volvo and the rubber seals on that were utterly
impenetrable, either with car washes, high pressure sprayers or any type
of weather. Probably the only area where they were better engineered.

Why the water ends up back there, I have never been able to work
out, but water has a way of 'wicking' or travelling along surfaces that
is quite odd. There's a term for it but I can't recall.

So it still could be the front window.


Cheers,

marcus
