Fixed this correctly in the end. I checked all the connectors on accessible modules under the steering wheel side of the dashboard and one was loose / not fully home, after pushing all the connections (think J519 module) the problem is properly solved. only 2 years later...

To close this thread the temperature before turbo is a red herring - so the 849 degree is irrelevant. My DPF issues were down to an air leak on the inlet side so unmetered air was being drawn in so the fueling was off as the MAF would not detect this additional air. Found by smoke testing the inlet. After replacing all the gaskets in the vee, to solve oil/coolant leaks plus gasket / diaphragm on PCV the problem is solved for over 18 months now.

Thanks mate, that would be great. here’s the other thread The inner rear lights on mine are quite bad so need to do something. As you say need to make sure UV protected after. Cheers Greg

Looks great, very similar to my 2011 but mine not the Le Mans. currently at 165,000 miles. What did you sort the rear lights out with? the standard polishing kit? Also next time you have it plugged in any chance of sharing the exhaust temperatures - pre turbo especially - we my other thread!!🤔 All the best

I had a similar problem where the front wipers would only work when the car was moving, rear wiper nothing and high beam not functioning (high beam flash would though) thought the bonnet switch lock but wasn’t that After checking fuses found no power before one fuse forget exactly which one. So fed power via another and everything worked fine (still has fuse protection) So in my case must be a wiring fault somewhere.

Afternoon all, I'm doing some trouble shooting on my 2011 A6, C6, 2.7tdi - CANA engine code. On my diagnostics and that of an Audi independent the temperature before turbo is measuring 849°C, but there is no sensor before the turbo on the 2.7tdi (there is on the 3.0 tdi). Can anyone point out if this temperature is irrelevant / red herring or is the reading is calculated from another sensor or a resistor somewhere? I have replaced the temperature sensor on the EGR cooler to rule this out but no change there. The reason for looking into this was over the last 2 years the car has had DPF regeneration issues, resulting in me having the DPF professionally cleaned at Home - DPF Clean Team, EGR cooler cleaned by myself - a real pain to remove, injectors removed and tested (all ok) as well as other unrelated exhaust temperature sensor failures. Any advice greatly appreciated on where this temperature input comes. Thanks a lot.
