trunk Gutter?

[Frupal]

This rubber ‘tube’ runs all the way around the deck lid. It has recently come loose on both ends. Tried to reattach with Gorilla glue and was less than successful. The rubber is rather stiff and springs right off of the glue. I have since taped it. We’ll see tomorrow. I considered replacing the whole thing - which I think is unnecessary - and also had some difficulty locating the part - so a little adhesive advice would be greatly appreciated.

Thanks in advance.

Had the same issue on both sides, 3m double sided tape and its been holding for 3 months already

same with me! I remember asking BMW about it and they quoted me over $250 plus fitting to replace it.... hmmm I may look silly but I thought at that price I've an idea. In Australia we have a product called maxibond by Selleys. I cleaned the old adhesive off the seal and boot surround and applied maxibond and taped it to hold it till the adhesive dried about an hour or so. Has held perfectly for the last 6 months no problems. job done!

contact cement works great. no problem after that even in the Texas heat

I had the same problem. BMW replaced under Warranty.

I used some leftover 3M mounting tape (VHB) I used from my lip kit which has been holding up so far.

It is not just rubber. If you look close at the end you will see the rubber has a rectangular channel in which fits the typical two sided trim tape that has thin rubber layer in it. If you want it to hold forever pick off the Gorilla glue, go online and buy some HG Power Glue, use just the liquid part, cover everything beneath good, just weep a bit of glue from the tip along the loose part, press on and hold for just a few seconds. It will still be stuck there when future archeologists find your car.

Just got this replaced by bmw, was told seals are not covered under warranty.

100 euro supply and fit so I said go for it.

Mine had exactly the same issue

Based on all the posts I've seen, and my own car, I think almost every car has this issue, so I assume an OEM replacement seal will develop it as well. That rubber seal is very stiff and doesn't to like to conform to that last few inches of a pretty tight curve. So it is constantly pulling against the tape adhesive, which the tape is not really designed for. I'm not one to save money to glue a part, but in this case I think it is the better and more permanent solution to overcome a defective design, provided you use the right glue.

Frupal, BTW if the one side of the tape is stuck to your trunk lid paint, you will need to remove that with Goo Gone or similar first before gluing.

The Glue name is HG Power Glue, not HD as I said above.

I just used some generic double sided tape from an autofactors and it's been fine in the UK extremes of sunny vs utter shit weather for 2 years of so now.

Thanks, Opie!

I have used this both in my 640d and in the M6



Strong enough to hold the gutter steady, but soft like a silicone (you are able to remove it by simply rubbing your fingers over) and doesn't screw your car paint.
Holding fine for years as now.

Have tried with double sided tape but with heat, water and dirt after some months it will come loose again or it will let pass water underneath the gutter, which is not good because it's meant to collect the water and drain in the hole down.

P.s. keep the inside of the gutter clean, even the one above (the gutter that meets the trunk with the rear windshield)
They will drain water much faster.

Should be 2 years warranty on parts ?

I tried 3m double sided tape on mine and has been holding really well.

I believe my car was covered under 3 year warranty as it was replaced at no cost approximately 2 1/2 years in.
