Your a star many thanks for the reply

I've got the elsawin wiring diagrams, I'll have a look later tonight for you to see the common point for those.

Thanks ian much appreciated been struggling a bit without wiring diagram

Firstly now we have a copy, clear all the codes then restart the car and see what codes come back, just in case any of those codes above are old ones not related to the current fault.

Here's a PDF of the engine wiring - http://www.ianhenshall.com/C6_RS6_Engin ... agrams.pdf

From your current list of codes it looks like the majority of the problems are on page 13 (N75, N112, N145) and page 14 (J299 - not J229) which all use Connector 6 (D108 on the diagram) on the Engine bay harness and all of which seem to be effecting the passenger side (of a UK car) of the engine.

Page 26 (N274) is on the passenger side but doesn't use Connector 6 and N276 (fuel pressure regulator 2) I think is built into the high pressure fuel pump No2, again on the passenger side although I'm not 100% sure TBF as I can't find it anywhere in Elsawin but Google suggest it's in the HPFP No2.

Hope that helps.

Hi Ian many thanks for the reply
I have cleared all the codes and the first code that appears is the n276 it also says to check Ecuador no2 as the same fault is listed there
Then when you start the car and let it run it produces the above faults I’ve tried resetting a couple of times individually also in Vag Com
I’ll have a run through the diagram and go from there will keep you posted

Many thanks for the help

Ian sorry to trouble you but could you give me idea where connector 6 d108 is located is it the black connector found to be front of engine to top right drivers side cylinder head there’s also a brown o2 sensor located near it
Thanks henry
