    Hi all, bit miffed off went to jack the o/s rear up to check my wheel bearings, started jacking on the jacking point and *crunch* it started sinking onto the jack. Closer inspection revealed its got quite rusty under there.

    Anyone had this fixed or done it themselves? I can weld but have no machine at the mo, basically just looking for advice.

    First case I have heard of it on an E46 so far.

    I have seen it on my own E36 (big heavy plate welded over the top) and a few others who have done the correct repair.

    Generally you'll need to remove the sill outer skin, make or repair a new load carrying box section inside, and put the sill skin back

    You'll need to go deeper than that!

    The sill is like a 4 inch box section, with an inner part making the chassis, and the outer part covers the side skirt and underneath.

    Inside there, there is a leg welded onto the inner parts, such as the A and C pillar which means the sill doesn't take the weight, it just covers the bottom of the leg.
    It's this leg that has corroded away, so don't use the BMW jack in it either!

    Been doing some research and to be honest its looking like a big job! Im going to start looking for replacement panels, like i said i can weld, if its that rusty round the jacking point im pretty sure the sills going to be shot too.

    So anyone know where i can get new sills from or is it dealer only?

    Nothing showing on hadrian car panels, which is the first place I look.

    I did see / read a thread somewhere showing a sill and jacking point repair on a 328 touring which shows the general idea, but I can't figure out where I saw it.

    Ok i cant stop worrying about this, it could of course be as simple as side skirts off and a simple repair of the damaged metal..

    However

    http://www.realoem.com/bmw/showparts...94&hg=41&fg=20

    Item 5 is what i believe is the panel that the jacking point connects with. If thats rusted and beyond repair am i correct in saying to remove such a big panel, the car would need to be in a jig?

    Am i overreacting here? bear in mind ive not actually took the skirts off yet to assess the rust :(

    that's still the outer panel, it'll be behind that.

    Still can't find the link/post.
    It was something like a 328 tourer, I even remember the pics where the guy had drilled out the spot welds, tidied up the car with a blanket over the block paving when rust proofing, then "spot welded" a new sill cover back on and blended all the joins.

    Tidy job too.
