Shouldn't affect anything.

When it's all buttoned back up, check these channels in VCDS.

91 - Cam adjustment actual - 28kw
92 - Cam adjustment specified - 28kw
93 - Cam phase angle - 1kw

If you see those numbers with the engine running, all is good  :happy2:

As above, check the 90's to make sure the cam timing is actually correct.... So many people put them back together a tooth out

In terms of Revo settings and checking for timing pull, check the CF (block 20ish from memory) under repeated full throttle runs once the car is properly warm.... Revo have a guide on what to log and when to adjust the settings.

Are these to be logged or just to show up when the car is at idle?

Thanks

Yep, as Dan said.   

You can also log 91 & 92 just to make sure actual and specified track each other, which is a good sign everything has gone back to together perfectly.

The 3 plastic oil control rings for the VVT adjuster (on the shaft inside the chain cover) are very fragile after years of heat cycling and oil bathing.  Snap one refitting the cover and you'll get a "Cam phase adjuster - slow response" type error and it will feel a bit flat to drive.  I would replace the rings mate.  AKS Tuning sell them.  New ones are considerably more flexible and easier to fit.
