Hi All, the ECU was at fault. I imported a second hand ECU which presented a whole load of issues re mapping the original data off the old ECU, this was unsuccessful as the immobiliser function could not be bypassed by the high street mapper, I had to get a specialist to remap the immobiliser, its now fixed but has cost best part of £900.00 (inc 2nd hand ECU) still cheaper then a new ECU. You live and learn.

Top tip Steve. I'll do that next and update the thread. Best

I've replaced the media circuit board too as it was not working hence the other codes above.

See below Steve.

Hi Steve after checking the ODBeleven, as you stated a lot of faults however, the main one being ECM (engine control module) Fault code 01314 'intermittent' I kind of had an idea it maybe that failing. Replacement unfortunately. Is there any merit in purchasing second hand unit? PS milegae previously stated was incorrect, 127k miles currently.

Steve invaluable information there. Apprecitate your help, I'll order the OBD eleven and run through further tests. I will keep the car as it is pretty low mileage 75k, the damage I believe has been it being sat for 12 months gathering damp.

Hi Steve, many thanks for the response, i didn't re code no, albeit I do have a basic OBD diagnostic? PS the electric engine cooling fans kick in as the engine spins over when it does try and start.

Hi help required please! I have a 2014 Audi Q7 TDI S line. It needed some attention, the car was running for about an hour in the drive after not running for 12 months (it did start first time). Then it just stopped. I had identified a slow start issue and noticed the earth cable under the bonnet attached to the block and chassis had partially melted, so I replaced and recarged the battery to full (new battery AGM) The engine subsequently did turn over however intermittently starter just 'clicks' and intermittently wont start either, just cranks over at a good speed, (fuel supply feels like) battery is good, any help would be welcome? Best
