Camshaft Timing
Re: Camshaft Timing
Have a search on Google for "VCDS camshaft chain stretch". From what I can see on this problem that affects some VAG engines (not ours AFAIK) it looks like the group 93 timing becomes progressively more negative as the chain stretches. This would imply that as the chain stretches, the camshaft doesn't turn as much as it should and lags behind the crank.
Not sure if that proves you or me right.

Re: Camshaft Timing
re 093 being in elsawin - I'm being blind - where is it?
The only reference I found in elsawin is what I printed to a pdf above - referencing 090 and 094 I think?
This is under Power Unit => 8 Cyl Engine => Engine Cylinder Head, Valve Gear => Checking Variable Valve Timing => Testing The System:

No. Install it on your PC/laptop etc.

Or the shoes wear. The new chain & shoes on Bank 1 have worked a treat.
It does, I had already googled it. Kurbelwinkel. What a great word.

Re: Camshaft Timing
Cool. I am interested then. These cumbersome VM do my head in. Haven't got a recent ETKA have you?
The 93 might be in with the ignition system / sensors instead of valve gear. Have a look for Hall sensors. If you still can't find it I'll crank up the VM and have a look for you.

Got it. Thank you. pdf here for anyone else that finds this useful.

Re: Camshaft Timing
I reset the cambelt timing based on eyeballing the exhaust timing marks, plus locked with cam bar and crank pin in.
You can see both intake and exhaust are pretty well aligned. I primarily tried to get the exhaust aligned - think I did OK?
However, Bank 2 is still marginal. So I guess it's either the hall sensor or the cam phaser that's off - but, intake on bank 2 looks good in the pics - so maybe it's doing something when the oil pressure comes up? I dunno. Will have a look at the hall sensor later to check that's on correctly (am sure it is) and then probably put the old dephaser back in bank 2 with it's new shoes on - I've got the gasket it needs on order already.

And the new timing results:
No SAI and the water pipe mode does make it easy to work on the OS (Bank 1) though, which is good:

Re: Camshaft Timing
Engine speed is different? Is this relevant? Spec calls for 730 - 790 RPM.

Only because the motor was not quite fully warm when I screenshotted it.
