I tried the search feature to no avail.After the heavy downpours last night I get in the truck drive to work make a right hand turn and I hear "sloshing" of water in the firewall right near the drivers side hood vent.Is their a drain hole somewhere that is possibly plugged ? If so , can someone point me to its general location ? TIA.

I believe there has been a TSB on that, although I forget the cause. Call your dealer -- it may be a warranty fix.

There was a recent thread on a similar topic. The poster there talked about water gathering on the passenger side though. Still may be worth reading: https://mbworld.org/forums/m-class-w...-freezing.html

I think there may be a clogged drain under that water.

There is a TSB but Ive run into one the it didnt apply to. Water will gather in cross member (crash bar) behind dash.

C43AMG

Solution ? Is there a drain ?

socketman

there r holes in the cross member but they are covered and you can get to the drivers side with the dash still in but not the pass side because the heater box is in the way

Had enough of this BS.Made appointment for next week to resolve this.I will post the results.

Open your hood, right beneath the driver's side hood vent, in the black plastic housing, there is a rubber cap of a drain which would open automatically when water gets in. Check that to see if it can help. IMHO.

Resolution -fixed under warranty.Repair bill references " DTB # T-B-62.25/09b".The "cause" listed - "Seam sealing incomplete , water entry into crossmember " .

I have a sloshing noise due to the water in the cross member under the windshield.
Couse: Incomplete seam sealant at the "A" pilar where it meets the cross member under the windshield...... According to the Technical Service Bulletin.
Any one has had any problem and was it solved successfully?

I have the same problem in my wife's 2009 GL320. Dealer said it is not cover under Mercedes CPO warranty. Is there another Service Bulletin Nuber for referance?

Gysand

I don't know the service bulletin # for the GL model ... This is the only service Bulletin for ML DTB # T-B-62.25/09b"what I found. ....First I called the Mercedes service, explained the problem and refereed to the Service Bulletin number. He ignored my "home work" and kept repeating that this is not a recall and he dos not find any service bulletin about this problem... After this one... I figured I rather to give the business to an independent service than wasting my energy with a Mercedes service adviser.... After a short phone conversation with an independent car repair shop's adviser, he puled the "Prodemand" and find the technical service bulletin imminently. So today I dropped off my car to his service for repair. I let you know the result.

Yeah, I've contacted MB and I'm waiting for a response. But, I'm sure I'll be taking the vehicle to my indy. Let me know your outcome. Thanks and good luck.

It isn't a recall. Unless its life threatening there is no chace it would be a recall.

Now it being a TSB is another story. And all a TSB does it identifies a flaw and how to fix it. If your car is out of warranty then your SOL.

Gysand

Yes it doesn't considered Recall. It is a production problem and most of the ML has the same problem. the reason I have not discovered it earlier because the car was always kept in the garage.

Gysand

My car got taken apart and the problem appeared on the same place where the Service bulletin pointed out.

Jdaly

Have the same problem with my 2010 GL450 so this problem seems to have existed for a long time on different models. My dealer is quoting $1,700 to repair what sounds like a Mercedes production problem they will not recall. Is this correct? If so, is there any real threat of damage to the car if I do not agree to the repair?

Well, it would be cool if the TSB were posted here for evaluation of DIY possibility.
