Timing chain for A6 3.0

[coconutaudi]

Hello there, is it possible to determine whether the timing chain of audi A6 3.0T is stretched or the timing about to jump using VCDS?
Thank you.

Yes, it is :-)

Somewhere in this forum You'll find this:

But this might help in the mean time

Engine - > Advanced Measuring
Block ID
048 Ignition timing adjustment cylinder 1
139 Camshaft adjustment; inlet phase; bank 1
140 Camshaft adjustment; inlet phase; bank 2
141 Camshaft adjustment; inlet; bank 1/2
142 Camshaft adjustment; inlet; bank 1
144 Camshaft adjustment; inlet; bank 2

There are two [Basic Settings] for the Camshaft that should run the test for the Camshaft adjustments.

[Test of camshaft adjustment intake]
[Test of camshaft synchronization]

Assuming it's this engine:

ENG103031 -- Camshaft adjustment: inlet phase: bank 1 (°)
ENG99898 -- Camshaft adjustment: inlet phase: bank 2 (°)
ENG99173 -- Camshaft adjustment: inlet: bank 1/2: specified (°)
ENG100104 -- Camshaft adjustment: inlet: bank 1: actual (°)
ENG100701 -- Camshaft adjustment: inlet: bank 2: actual (°)

The easiest way to find these will be to go to Advanced Measuring Values and put 'Camshaft adjustment' in the search/filter box.

I've never seen these jump yet. I've seen them break the guide when the chain has alot of slop in it, but the same deal yes. Chains are a thing on these engines as well.

Thanks guys, appreciate it because they are valuable information. These information are available and can help us avoid catastrophic damage but we need to know the correct wordings to search for them. Definitely can’t search using with the word “timing”.

Yes Uwe, that’s the engine. Having known the specified degree, what are the acceptable deviation from the specified values whether camshaft is in advance or retard before we can determined that the timing is bad enough to get a timing repair?

I think the max limit is 25 degrees of timing IIRC. At idle you should have almost zero, it will add timing as rpms climb unless your using shit quality regular fuel and not premium then it will add timing to compensate.

Thank bro, appreciate it.
