Shans211 Posted January 2, 2010 Author Report Share Posted January 2, 2010 COuld be a loose connection, or just some crap in it fromt he roads of late. But.. D3 motorised handbrakes do have a habit of breaking, had one replaced in mine. Thanks for the reply on this - yes i am hoping its the road grit thats got to it and am waiting to remove the wheel and get it cleaned up and check the connectors, however i have lately been noticing at random intervals when i have parked up (and not used the parking brake) the motor making noises as if its trying to engage. maybe that was the tell tail sign that something was going to happen soon.... out of curiousity did you get yours replaced under warranty or did you have to reach deep into your pockets? Any idea on costs for a replacement motor/mechanism? Link to comment Share on other sites More sharing options...
PsYcHe Posted January 3, 2010 Report Share Posted January 3, 2010 Mine was under warranty, but I think they're 'not cheap'. a8parts have one for £125 on ebay at the minute. Link to comment Share on other sites More sharing options...
RichardW Posted January 3, 2010 Report Share Posted January 3, 2010 I cannot help you with the problem, but, the noise you have heard after parking but not applying the parking brake is quite normal. My A8 D3 does this and has done since I bought it over 3 years ago. I guess that the motors are adjusting the pad gap to compensate for wear (which is normally done when you apply the parking brake).

Shans211 Posted January 5, 2010 Author Report Share Posted January 5, 2010 Thanks guys for your input - much appreciated... I have been quiet on this the past couple days as i wanted to investigate further...the damndest thing - i had the car steam cleaned after the salt n grit on the roads over new years, after an hour of the car being washed (it wasnt that bad mind) the messages have now disappeared of the Dashboard.... I am wondering if this is a temporary repreave however i will keep monitoring this and see where it leads - it seems more electrical than mechanical failure so lets see what happens over the week. once again, many thanks indeed for your inputs.

PsYcHe Posted January 8, 2010 Report Share Posted January 8, 2010 I've just had mine fail today.. Had to abandon it in next door's driveway as I couldn't get back into mine with 3 wheels . Wheel off, and a large spray of WD-40 on all the electrical bits (keeping away from the pads) and away it went Link to comment Share on other sites More sharing options...
