So I have found my trunk leak/leaks. The weatherstrip at the end of the trunk under the rear window and where it wraps slightly around the bottom of the window is the main problem. This area does have some glue or silicone applied to it as well. Has anyone has this replaced by a dealer and if so can you give me an idea of the cost? I could use silicone on it myself but this would make it even harder to clean up and replace with new down the road. I am pretty sure it is all original. Thanks.

 

i did a search for you...the answer should be in this thread...

Also check the drains in the weatherstripping groove and see if they are clogged or have a leak in them also. Others have found that to be the case.

 

Tom Bgw70, thanks but that link does not work. But I have done several searches.
Did get a quote from the dealer yesterday and he is installing today. Should take care of it. And I'd encourage everyone (if you haven't already) to check for leaks under the hinges, this is the area I have seen in 5 other 430's. Many times not a lot of water and it will dry and not leave a noticeable mark or stain.

 

please try that link again...
