2.0 TFSI - When should I change the timing chain?

[ssmith93]

Hi, new to the forum.

I have a 2009 Audi A5 with the 2.0 TFSI engine. The car has done 215,000 miles, however it had a complete engine replacement in 2014 at 109,000 around the time when I bought it. It has a CDNB engine (E888).

I am aware that Audi tell customers that these timing chains are 'good for life', but I appreciate that actually this isn't the reality. Having done some reading there appear to be two ways to determine if the chain is due replacement:

1. The camshaft phase position adaptation stored in the ECU.
2. The number of grooves protruding from the tensioner body from the inspection port.

I haven't had a look at the tensioner yet, but my "Camshaft Adaptation Intake Bank 1, Phase Position" reads -3.85 degrees.

I am wondering if anyone can share specs as to when the chain should be replaced. I've come across various figures but struggled to make sense of it!

You should be fine at -3.85° of adjustment. Start thinking about it once you hit -5° of adjustment. There is a mega-thread in the B8 forum covering a lot of supporting info: Clicky click

Thanks, took it for a drive this morning and now it is measuring 0.00 degrees. Strange, i'll try again later.

Good to see you still around "holding court" now and then...
