Alfie6

Hi - had the same problem and my local garages did not the soft ware to unlock the unit. However I found a local auto electrian who had the software and he successfully unlocked it.

Many thanks Richard for your help. I have dismantled both front brake calipers and though the pads and discs are as new, all was really dry of grease. Using the ceramic I greased all as appropriate. Just done a road test the rattle has basically gone. Only a little rattle over pot holes which should avoided anywhere. New caliper springs and gease up -job done. Thanks again.

Thank you for your reply. I have the invoice for brake pads ( dated 18//07/23) and they are Borg and Beck BBP1766 from Motor Parts Direct - I have checked their web site and they are correct. I note new discs were also fitted at the same time supplied by them BBD4509, which are correct. With regard to carrier wear the car has done 12500miles, and don't believe the car has been driven hard, since I know the previous owner, who has owned the car from new. Thank you for the very helpful diagrams and note the only spring on the caliper shown is on the outer which I have replaced. I find this unusual as other calipers I have worked on have springs in the base of the carrier and hold the pads tight in the holder. I have ordered some ceramic brake grease and will carry your recommendations and will let you know. Thank you again.

Hi, its Alfie 6 again, and I now intend to inspect the front calipers. Before I do so I would be pleased if anybody could direct me to an explosive diagram of the caliper unit. Having worked on previous calipers, there appears to be a lack of support for the pads, having only the outside spring to stop rattle of the outer, and the cone one which goes into the piston? Please note that my car is an 2008, which is different from the later models, which has an over lapping external spring. Any help would be much appreciated.

Hi - I have recent acquired a 2008 A6 (C6)avant sline and I am experiencing rattle from the front brakes driving over rough road surfaces. I note the car has recently had new discs and pads and only 10% worn. I have renewed the caliper springs on both sides and this has largely improved the problem but annoyingly there still some rattle from both sides. Being a sline with harder suspension is this a common problem on these cars on our bad roads. Further my local garage has inspected the suspension and can only find that anti-roll bushes may required to be replaced in the distance future, and could only be an advisory on the MOT, but offer no more advice. Anybody had the same problem and solved it?

Hi I am new to the club and fairly new to my 2008 A6 and am experiencing the exactly same problem. Where did you get the replacing door lock that solved your problem and how did you know it was that ? Any further advice before untaking repairs. Regards

My fob will not now open my drivers door. Its happen now and again over the last six months but now it will not work at all. I have checked all other functions are working fine and new battery. Just wondering did you fix yours and how ? cheers
