Sunroof leaking but not the actual sunroof.....

I have water coming in from the passenger grab handle near the sunroof. Ever see that happen?

Yes, you could have a leak in one of the seals on the roof of the car likely around the sunroof.

I have seen this once or twice, it only seems to happen if it is raining extremely hard and the car is parked in the perfect position so water pools up instead of draining through the sunroof drains, or the drains are clogged.

Same thing happened to me. One short visit to the dealer and the seal was replaced and problem fixed.

How much did it set you back? I cleared the front drains and looking for the rear drains (must be hidden fairly well).

^was free. covered under my extended warranty.


i dont imagine it would have cost much though. took less than 10 mins and parts were probably, dare i say it, cheap.
if you have a good relationship with your SA, i am sure they can hook you up for such a minor issue.

Looks like I will have this fixed. It poured the other day and water returned. Only happens when it pours and never under normal rain.

You remember how much it costs to replace the seal?

Crap. So, I am googling this yet again.

I have the same problem of the sunroof leak under heavy rain, finally I found that it is no related to the sunroof seal.....l it was the sunroof drain pipe seriously corrosion (rusting) and made leak. I Need to grind all the rust on the pipe, and added some anti rust paint on it as temporary fix

You should check

1) open the sunroof and put some water(several cups) at the sunroof side track. Water will drain through the drain pipe. If u have problem to the pipe. Water will drop ontop from the headliner, then....
2) need to partially remove the headliner and check for the roof drain condition.

I think this is a common problem to w203 model.

I will st more photo tomorrow.
