Hi, I checked the boot and there was a small small bit of what looked like damp or oil under the metal bracket which holds the module, under the battery etc. We ruled out any affect that this would have had as it wasnt in contact with anything and the plugs were all dry. I have installed a push button for now to bypass where the fault is until I get an auto spark and get paid again as finding faults in Audi's are expensive. One question I have for people reading this thread is, do new clutch master cylinders (with clutch switch) need coded to the car? If they do then I could save myself a full auto spark investigation. I replaced mine with a genuine 1 from TPS but didnt code it. I will keep this thread updated. Thanks John

Thanks again Steve, Yeah im gonna have a guy look at it who has a VCDS system and try to clear all tge faults. My OBD11 is good but keeps all historical faults too. Looms becoming brittle seems an ongoing issue on the A6C7s especially the Ultras. I will post on here every step because if I can help others and save them some money then thats how these forums are supposed to work. Thanks mate John

Thanks mate. Yeah, we were at it all day today. Had the full wiring loom cut open but couldnt find the problem. We ran a wire across the starter wiring and bypassed it for now. Car still starts on a button for now but still flags up the "stop start fault". The auto spark is off till after new year so had to do something to get it mobile again. Car was previously a taxi so the harness has been hacked in places. Im guessing broken wire in harness as you stated may be my issue as its in same area that my last multiple fault issue was and it was a loom broken in 4 different places. Thanks for the help. John

Thanks Stevey, I had an auto spark fix my older problems with the multiple faults around the off side ABS/wheelspeed sensor which he found to be 5 breaks in the actual loom along the firewall/bulk head up around the DPF etc. Im wondering is this same issue with the wiring from starter up in same direction. Thanks John

Hi all, first time posting. My 2015 A6C7 wouldnt start(start stop not working, Visit workshop) and through up loads of faults mostly including clutch switch, Clutch posistion sensor, and a few on modules not working. Car starts on a bump start but not on a jump start. Cleared faults but still no start. Battery is above recommended %. Replaced clutch switch which is connected to master cylinder so £200 and still not starting. Still saying electric module intermittent. Any ideas of where the problem is? We were thinking electrical failure in cable to starter. Run a wire direct to starter and it starts no problem. Ive had damaged wires on this side of the car before. Had multiple warning lights on dash and was in fact corroded wire in loom to ABS sensor. 4 different cracks in wiring. Any idea would be appreciated. Thanks John

Did this solve your multiple warning lights issue? Thankyou.

My 15 A6 does this too. I have done all that it says on here ie new battery, ABS sensor etc and still mine comes on as im parking or pulling out of a juntion. It always seems to be when my steering wheel is turned left for some reason. A mechanic has informed me that it must be the wiring loom for the left hand side of the vehicle and its rubbing somewhere. I dont know how this could happen but between us im sure someone can work this out. Thanks.

Hi, I changed my battery as suggested on here, NO difference, I changed front ABS sensor as suggested on here, and NO CHANGE, and still my lights are coming on. My lights come on when I slow to change direction or go to reverse park. It seems to be clutch related or gearbox related. Also I stop my car, switch ignition off and on again and rev the engine a little and the fault lights go to start again but dissappear..Then they stay off for a bit.
