Hi All, Car : 2015 A5 2.0lt 150hp Couple of issues so far. Had car around 3 weeks, had ATF & Filter changed Friday as history shows last change 40,000, car has 98,000 on it Particle filter warning came on dash, took car for spin down motorway but couldent get it start regen, but cleared code and checked soot levels via VCDS and seem ok Other day I disconnected negative terminal in battery to do full system reset, all went well until this morning, start car and get ECS fault, test battery at terminals eng off, 15.7v, engine on rises to 17v Should I fully disconnect battery to try again or does it sound like battery issue just got VCDS but not sure how would test battery with it. Will say previosult start/stop was disabled when started car, after batt disconnect start/stop was auto enabled until this ECS fault, after I cleared that start/stop is again auto disabled (fine by me), not sure if related. Update, used VCDS to clear fault, and been out in car and fault not come back on, but strangly lost some DAB radio stations normally listen to. Oh 1 other thing, when took on motoway when I used the flappy paddle to drop gear, it would only hold gear few secs before going back into normal auto mode ie. D/S depending.
