Nov 28, 2016 · Hello All, Just wondering if you would know what this is.. Sometimes, after the car has not driven for a day or so, (MY2014 A5 2 TFSI 225 quattro SB) it seems to have issues where the cruise control doesn't work, the throttle response is delayed, AND there is a slightly gruff tone to the Mar 3, 2016 · The Bowden cable being £10 and the door lock being £125. Quote for labour being £200 (1 and a half hours work). I won't be paying Audi £200 to rectify a common fault. So I will be buying both parts and taking it to my local to fit for about £50. Hope this helps someone.
