Have an annoying door rattle on rear left door.
Have used gummipfledge on the door and window rubbers, that didn’t fix, have also done the door lock rod pin thing mod to stop that rattling.

With the window all the way up I get the rattle, with it cracked undone it goes away, any idea where to start?

Yip sounds like the dreaded creak between the top of the felt door trim and the black plastic trim frame.

You can cure it by wiping it all down with silicone remover, but it will come back. The only fix is to use the tape method see here..

I did it on my 340 and it was silent. I'll look up the tape I used and post back.

I’ll have to give that a go, funnily enough it’s on a 340i too

If it's not the LED strip light rattling, it will be as above. I found gummi pfledge did sweet FA - made it worse in fact - but what does work on mine is Meguiars Endurance tyre gel. I just wipe a thin layer onto the door rubbers after I'm done doing the tyres and that shuts them up for several weeks.

That's coming up as a dead link but tape sounds like a good plan so long as it doesn't peel off from weathering and door openings/closings?

Happened on my f31 330d as well.

Thanks for that.

So the only permanent solutions are BMWs version of Gummy bear Pledge, or 3M squeak reduction Polyethylene UHMW tape.

Both are mega money - probably because they work, so it's either cough up the £££££s boys, or keep rubbing the KY on every week

I might try this in 19mm flavour - https://www.affixit.co.uk/uhmw-tape.html#180=832

The 3M stuff costs a fortune, if you can actually find a UK supplier.

I've still got some tape left that I used, will look to see if I can find it to advise which one it was, I got it from ebay. It certainly worked, car was silent after that. BMW installed new door seals and that didn't cure it either.

Okay guys, this is what I used on my car it's called 'Hoerev'.



As you will see it looks white,(first pic below) but is not, it does however have an opaque finish (2nd pic), but when you apply it it's sort of clear, (3rd pic).

You apply it on the car where the felt/rubber top door trim meets the bodywork. I closed the doors and applied a strip of masking tape to the position where the it met the door and used this as a guide to apply the tape, so it's not visible when doors are shut.

Mine was a black car so with warmed tape applied to a degreased and cleaned car, applied slowly with pressure to drive out any air bubbles, although visible, was not really noticeable. on lighter colours it would appear clear.







As you will see I don't have much tape left but guess I'm unlikely to use it so if the OP wants to try some happy to send what I have as a sample.

Hope it helps.

This afternoon I’ve gave everything another clean and gummi’d the F out of the rubber and felt bit and see if that does anything, if not I’d happily try out that tape

It'll likely shut it up for a while but it will come back once it dries out, as it's not the rubber seals it's the rubber with the felt on that causes the issue on the black trim. Tape fixes it for ever.

Some car shampoo makes it worse too, Maguires NXT was one of them on mine.

I used the silicone remover (that BMW supplied), on felt / rubber and black trim and the areas where the door rubbers meet the car, so it was squeaky clean and that works for about a week and it would come back. So although the complete opposite, I found that better than gummi .

Ironically, it is the flocked surface that is supposed break the stiction between the roof trim and door seal

It's horrendous over the winter months when all 4 doors have dried out. Sounds like a 1980s MK2 Escort wobbling it's way over a cobbled street. It also highlights just how much the unibody flexes as well.
