    A week after lowering my Avant (30mm with b5 spring cups) im now getting a knock/lump on the rear when the passenger rear wheel (sounds like its coming from here) catches a pot hole. Doesnt always seem to do it and only on back roads. Have been and had 4 wheel alignment and they couldnt see anything wrong. The noise sounds like the boot isnt shut properly if you know what i mean. Any ideas???
    Probably not related at all but i also had new brakes, fitted new alloys and tyres A6 Slines Et43 with 235/40/18 and a full service including fuel filter at the same time just to give as much info as i can.
    Thanks

    I had a similar noise on mine, turned out to be a broken spring - pop both rear wheels off and check the base of the spring - mine had broken off and the broken piece was knocking about causing the noise

    Well, turns out my knocking is from the Rs4 RARB. The bushes have started to slip off???? Mymate thinks they may be a bit soft. So gonna order some poly ones and see how it goes
