I believe that I have a sunroof leak. I found the two front gutters.
For anyone else with this problem, the front drains are in the front
corners and can be seen when the sunroof is open. These gutters drain
out the body near the top front door hinges. If these gutters are
clogged a standers dry cleaner hanger is the right size and length to
clean them out. Avoid the painted hangers, the pant peals and defeats
the purpose a little. An unwound and straightened hanger should be
just long enough. If you have the door open you should be able to see
the hanger exit the gutter tube. The front gutter exits are behind the
door and not accessible.
I am writing to the group to ask if there are rear gutters and if
anyone knows where they drain. It seems that there must be rear
gutters. Where would the water go when the car is parked on an
incline? Any help would be appreciated.
There are rear shunts. Since i have a TD I do not know where they drain
to. I ended up removing the whole headliner which made everything a lot
easier to work on. So, if you unhook the rear hose that run the water
out, you can get a wire into it to clear it.
Thank you for the reply. It is god to know that there are rear shunts.
I would like to avoid removing the headliner. Does any one know where
the rear shunts for the sunroof drain?

I agree that removing the headliner is an uber bitch--and is nothing
compared to putting it back in. Now YMMV, but when i found my pan had
turned to flakes, the only way to get the tubes cleared was to push the
crud downward. I'm pretty certain that it would have been pointless to
try to clear them from below. These are big words from someone who had
to remove the headliner anyway, so for me it was a snap. I'd say in
your situation where you have no reason to remove the headliner,
starting from the bottom would be the first thing to try. However,
don't be surprised if you do have to go from the top. Then again, if
you do, you can remove the actual sunroof and reach back into the back
of the pan and do it that way.
Thank you for your reply PT. Is there anyone who has advise on
removing the sunroof to clean the rear gutters? Are there any pitfalls
to avoid? It woud be very bad if I could not get it back together.

Don't sweat it. It only looks hard, it's so stupid easy you'll

The sunroof panel just pulls off by pulling straight down, hard
and there's one pin that connects the cable to the roof. It all just
comes out after that and it stupid easy to put back together.
Changing spark (or glo) plugs is MUCH more complicated - it's that
Keep in mind though the ONLY grease you can use is the proper
MB sunroof grease. Absolutely nothing else works properly. You
can get a small film cannisters worth of the stuff for a
couple of bucks from the link below, MB sells it in 1 lb tubs
which would last a 20 car owner several lifetimes.
