Just coming to the end of rebuilding an A6 C5 Avant 2.7t AJK with Tip FAW(5A). Started up fine after priming system, and didn't even have a MIL light!! Only the Airbag light which was a known issue.
Heat cycled it, a few times, and emptied the flushing oil and water out, for the good stuff. All done the past few days.
Set about fixing error codes:
A/C pressure switch
Siren internal batteries dead
Airbag igniter Drivers side
...Guessed clockspring, but was pinched wires. insulated and cleared codes..all good.
Start it to test A/c switch and sounds like a bag of spanners. Sounds like it's misfiring like crazy.
No MIL, check Measuring Block and no misfires detected. No error codes for engine. No failed cam/crank sensors....no lack of fuel...
Any ideas?
