    Right - I got the non-led number plate bulbs from T8ups as I had issues with the led ones on my A3 previously. Gone to fit them into my A4 Avant today. Fitted the left holder + bulb - changed screw for stainless steel allen screw - applied some black rubber sealant as the rubber seal had started to perish - tested it and all good apart from the fact that the right light now doesn't work with the normal bulb in it. So went to swap that one out and found that previous owner had rounded off the original screw, must have cut out the old holder, fitted a new one and fitted a self tapping screw at an angle to bypass the rounded off screw shaft! On removing it there has been a lot of water ingress as the angled screw isn't allowing the holder to sit straight in the cut-out

    Whatever I do here the new holder will need to be stuck in somehow so without replacing the whole black strip I feel the best thing to do would be to bond or glue the new holder in place. So here's the question........

    What will last longer (as I won't be able to remove it if stuck in!) an OEM holder with a non-led bulb or the integrated 18 led units that come as part of the holder?

    Also what would be the best product to bond it in with please?

    Thanks for any advice

    I'm not too sure what bit is knackered, can't you just buy a new one of these?

    Yes but it's £30ish for that part plus a new pair of OEM holders and then the time to fit it so figured it may be easier to do one of the options in the first post

    I've just done this on my Avant. Purchased LED bulbs, and found a self tapper in the light at an angle - must be a dealership fix!

    I removed the panel, drilled out the broken bolt, re-tapped, coat of satin black (left over from the peeling wiper arm job the weekend before!) and replaced both light lenses with new units.

    I would suggest either repairing the housing or replacing it. Gluing the lights in seems like a bad idea....

    Replaced it all today and working great now. Also stripped down boot handle and relubed it and the boot release works like a dream too now. Getting the trim off was a pain in the a** though

    Avant part numbers - black metal moulding strip - 8E0 827 576 3FZ
    Bulb holders - 8E0 807 430 B and 8E0 807 430 A

    Might be, but I would have thought they'd say "new trim": more likely just a well known workaround to the screws corroding and snapping and not having to waste the time and parts to get your motor back on the road.

    I had the same on mine the first time I checked it: a TINY dab of clear bathroom silicon sealant the first time I "resealed" it and it popped back out fine afterwards when I had ordered the new bulb holders. I filled the angled hole with silicone sealant and because there was still a snapped-off screw in the trim, I put a new, small, self-tapping screw in at an angle.... seems to be fine, but just a better seal than the previous setup had (sits completely flush and no water ingress).

    Moulding - 29.61
    Bulb holders - 7.58 each

    not with vat

    They also do a black plastic version of the moulding that comes with a pair of bulb holders included in the price for about £65 - apparently it was produced to stop the corrosion problem
