Managed to get two ARE heads, just in case. But anyone know where I can get cam cap bolts? 058 103 460A/C or WHT002015 {last is most recent revision, M6x40) Have a lot of helicoiling to do, as sure threads will 'yeild' when torqued to specs!!
There was a reason my nickname was 'Double Lucky Leo'...
Turns out the 'actuator test' must have found a sticky cam adjuster or two, causing the timing chain to skip....... causing the timing to be out.....then the beautiful marriage between valves and pistons.... YEAY!!
On the plus side, this...
Took plugs out vented combustion chambers with compressed air and tube. Cleaned plugs, even though new.
No change at all.
Got stock AJK bin from NefMoto and compared to my bin with HxD and identical.
Must be stuck VVT adjusters?! yes/no?!?
I think I must have 'cleared leared values' thinking it was just the ECU 'drivers style' and c**ked something up. Litterally sound as if 'the ht leads are in the wrong order'!
I'll wait until I get the VCDS stuff and then see what I've ballzed up.
Mechanically it has not changed. That'll teach...
Only when it sounded like ****. Popping off cam covers at mo...
All looks good, chains tight nothing knarled, except my knuckles.
Totally clueless. Shall put back together and check fuel pressure...

No, not aircon. Removed aux belt. Has new timing chains and guides. Think it's both the vvt tensioners sticking at the same time...
What are the odds[emoji24]
Will investigate to find out latter.

Pops and burps like a misfire, like timing is out. Surely, turning off the ac would disengage magnetic pulley. Shall try now...

Only thing I did was an 'actuator test' which basically tests solenoid in engine: evap, purge, etc, and injectors. All clicked normally.
Then on restart....bricks in a cement mixer!! Sounds like the VVTs have adjusted themselves 'out', but have not returned.
Any advise how to resolve/reset? Got...
Advised to post on other sections....
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...
Check maf/map sensor, clean with brake clean or ipa (not ale!!!).
Also might be a lambda issue, as my mil light comes and goes under heavy load up hill, but that throws a code.
Even a dodgy ignition coil / pack would show a misfire code.

Fair enough.
I'd be surprised if cam wear would trigger a code, I'm no expert.
Hopefully some people which are a lot more adept, shall chime in.........

I'd check sensor first. Then check timing on timing chain second. Not sure what setup on 2.0 tfsi is, but on b6 2.4 v6 & c5 2.7t a lot of people seem to get timing setup out on cams, causing similar problems. 16 link gap, but offset depending on bank and cam.
How good was garage that did timing...
Either way it would be the contacts. Learnt from owning an Alfa, it's worth buying some electrical contact cleaner spray.

Yes, had a sporadic bulb failure warning on my b6, was switching between rear right brake and centre brake. Cleaned contacts for rear right cluster, and put new good quality bulb in, and all good. Had previously use emergency bulb from kit, suspect resistance caused false positive on the...
