    Odd situation: BMW E46

    Hello,

    On my bmw E46 coupe nothing has really broken but it’s more of a situation that has happened during a repair and I just wanted to run by my solution to fix it...

    I’ve got the usual rust on my rear wheel arch, and a hole has formed. Was going to fill it up and my dad decided that it needs to be fillied up first, so he’s cut a bit of metal of and it’s fallen into what I think is the sill.

    Now we can’t get the bit of metal out and my idea to just stop it rattling is to use expanding foam, would this be a good idea and can anybody give me any sort of advice on what to do about this stupid piece of metal inside my bodywork now...

    I should think a sticky cavity wax would be a better solution than expanding foam. How big is the bit you’ve lost?

    Drop a magnet in. ;)

    Always apply the flammable cavity wax before welding up the hole if given the choice lol

    Was he going to weld the new steel in or just put it behind to stop the pudding falling in?
    If welding and small,l weld a nail to the middle,

    Well yeah that goes without saying surely? Do it after lol. I’d wager a magnet would stick to the side before falling to the bottom...depends where the hole is of course.

    yeah... found out that expanding foam isn’t a good idea after talking to some people, as apparently the first minis had expanding foam in the skills and they rusted within no time.

    Cannot use a magnet as it’s aluminium and I didn’t realise how deep the sill actually goes on the car, I think my best best is to just leave it and hope I don’t hear it.


    It was intended to cover a hole and then I was going to put plastic padding over it, my wheel arch has the dreaded rust just above the skirt.
