thank you for your reply, i don't have any continuity from pin 3 grey and blue wire clutch sensor to pin 44 grey blue t94 ecu pin connector, i struggle to read the wiring diagrams :(

in theory yes BUT you might have a fault on the reverse wire to the one that faulted for me. it cant be only one of 2 wires

Thanks for the reply. The fault last year was a level sensor at the rear which made it drop at the back as the car didn’t know the suspension position. The issue I am trying resolve is less crucial as it is slow intermittent problem that only occurs if the car is left for a while

Thank you for the information you have provided very helpful, i know this is a few years later but can you help? I am trying to fix my Audi a6 2014 that wont start impassable clutch switch signal, i have a strange 3v on clutch sensor pin 3 grey blue wire also have constant 12v battery power at pin 44 grey blue wire on ecu T94 connector. from my understanding of the information you provided i can run a splice wire from pin 3 on clutch pedal sensor to pin 44 on ecu to solve the problem? Thanks in advance Daniel

Thanks Rob, A rather strange service history - covering 17k miles in its first year at Basingstoke. The following year it then goes backwards! Possibly ‘hickory dickory docked ‘ as we used to call it - aka the mouse ran up the clock. It then seems to have had a quiet life around Shrewsbury for 3 years, before having its skirts lifted and covering 16k miles partly in Germany. Where did you buy it Rob, and how was its service history described, and did you have sight of its SH before purchase? Have you ran an MOT history on it? Anyway moving on:-. Your proposed plan sounds good, although I would renew the air filter alternate years rather than annually. Same with pollen filter. Fuel filter - say every 3 years. I would think it has an Haldex unit - being Allroad. Coolant - could be renewed every 50k or 5 years. Auxiliary belt again 50k or 5 years. Full underside inspection and wax treatment annually. In case it helps - I’ve always used VAG’s Quantum brand to good effect, and only Mann or Bosch filters. Filters and other components are usually bought from Parts in Motion. Both oil and filters via. P in M’s EBay listings. Quantum Longlife 3 also from reputable sellers on EBay. Regards, Gareth.
