Water leak in trunk

If many of you don't look inside where your spare tire is, you may miss the leak that I have on mine. It goes below the plastic that holds the spare tire and onto the painted shelf surrounding it. You wouldn't know its leaking if you only open the trunk normally. I have it at the dealer and they are subbing it out to a body shop.

I'm also having the front lower control arms replaced since it has that steering wheel shimmy between 60 and 65 mph. Thanks to this forum, I knew there was an internal repair memo on this from Mercedes as far as I know.

The car has 39,000 miles on it and needs new tires soon. Its been great!

We have an 07 E350 with water leak in trunk. In our case the source of the water leak is on the left side of lid opening between the rubber seal and the outer part of the quarter panel. I think it is coming in from one of the black plastic "buttons" that are in the 'gutter' section of this area. The water comes in there runs toward real of car and down on the left rear inside. Then comes down along the left floor area and drips down inside to the compartment of spare tire. I still have not fixed but hope to tonight.

FYI: For leakage from spare wheel well mention DTB P-B-61.10/02 AUG03 the adhesive bead between the spare wheel well and the body may not be evenly applied and therefore not leak tight.

DIY: I can forward a copy with repair instructions – body sealant part #1686700093 (MBUSA $90 list / 72 net).

MY 2004 W211 E270 CDI.

Have the same issue as Pierre Louis' first post (water leak in the spare area), except unfortunately I am way off the warranty period.

I have identified the source to be the crease joint marked in pic below:

I attempted to remove the rear license plate panel to reveal what lies behind the joint, if the seal is broken etc., but could'nt remove it for the fear of breaking something. So as a temp measure have sealed the crease joint with a clear silicone sealant.

My queries:

1. Can someone help me with the removal procedure of the panel?

2. Also, is the DTB P-B-61.10/02 AUG 03 available on the net?

I had my 06 E350 4M repaired 3 times for the water leak in the trunk, the water was accumulating by the spare tire.
The dealer stated after testing that the water was coming from above not below.
While I never got a straight answer from the dealer on the cause, the last fix included the replacement of the 3rd light which has a more robust lens seal (MB Bulletin) than the original and the tightening of the trunk closure. The effort to close the trunk is now higher... but it has not leaked in over a year.

I forgot to mention, I had also silicone sealed the border of the third brake light. No success with the leak, which then led me to investigate the creased joint.

Also, the inner panel behind the license plate is wet just under the creased joint, but not all the way upto the third brake light.

I poured water over the joint and sure enough it came through the inner panel. So its definately the rear panel to body seal which has worn.

Will have to remove it to inspect the seal and then do whatever is needed.

However, will try resetting the trunk close postion as suggested by you.

About your not getting a straight answer from the dealer...I asked my MB authorized dealer to gove me an estimate for a SBC Brake Flush and he said he could give it to me only after I showed him the car and he hooked t upto the DAS. Sounds odd, considering here i n India they change the oil every year (and not once in two years). I thought ht eleast they would be able to give me was an estimate cost for the oil and the labor, but no!!! So, nbow am looking at a way to do the flush my self.

Thanks.
