What should the values be?

Ok thanks for your confirmation. I’m assuming if my camshaft inlet phase values are -750° to 0.750° at 119k it’s perfectly fine because the threshold is 11.0 to -11.0 (failure).

Any other inputs to read on VCDS to determine if timing parts (chains / guides) should be replaced that you know of ?

Thanks for your input I appreciate it

I researched a bit and will be adding PN VAG-059193175F the oil pressure check valves to the car while servicing the supercharger.

Wow, I had no idea this was a thing. If/when I decarb mine, I will definitely be (re-)adding those. I had no idea they went cost-cutting on the B8.5 at the expense of startup oil pressure
