Here is at idle...

Here is revved up a bit, you can see the values increase in 91 and 92 for each bank...
Attachment 17478

Not really sure about 93, it's there, but the values are static.

Thanks for info. Looks like I got electrical issue.

Have you tried testing/replacing the cam position sensor (G163) on bank 2? You don't show a value for Phase Position Bank 2. What I'm reading says that value is a calculation using the Engine Speed Sensor (G28) and Camshaft Position Sensor(G163) readings. It should be somewhere around 0 +/-6.

I'm pretty sure if there was something wrong with the Engine Speed Sensor(G28) the car wouldn't start.

17755/P1347/004935 - Camshaft Position Sensor 2 (G163) / Engine Speed Sensor (G28): Incor. Correl.

Possible Causes

Timing Belt/Chain incorrectly installed

Timing Chain probably lengthened

Camshaft Position Sensor 2 (G163) faulty
Engine Speed Sensor (G28) faulty
Possible Solutions

Check Timing Belt/Chain installation

Use Measuring Value Blocks (MVB) to Check Timing Chain

Check/Replace Camshaft Position Sensor 2 (G163)
Check/Replace Engine Speed Sensor (G28)

I could be completely wrong; just throwing it out there.

That's what I thought, but in group 92 adjustment bank 2 would not show, if the sensor wasn't working. Or is there another sensor that reads that info?

[AndyRS6]

Just check g163 sensor -working fine, any suggestions?

You're using Ross-Tech VCDS you said...so if a sensor was out it would tell you. Something is not connected it seems...

Update, problem solved, all it cost me $15 and luck. So the problem was cam chain tensioner. I got also 2002 A6 4.2 and the part# was the same. Vent to salvage yard with my tools and found 2002 4.2 with low mileage and full engine, picked up both tensioners and some other parts.

Also found what was wrong with my old tensioner, piston under solenoid was stuck, that what cause my ross-tech in group 93-4 to be blank.

piston
good position
bad, i also check in my 4.2 and salvage yard 4.2 ,piston suppose to be out.
My new logs

and my projects

also need transmission output seal and axle seals.

If all your timing marks are lining up, the only thing that could possibly cause your code then is a bad tensioner...

Winner, winner, chicken dinner.... Too bad you lost more down time chasing other things. Glad you're all up and running again.

Actually it was very productive, i did a lot of research and learned many things, so time was not wasted. I appreciate your input and would like your opinion; my transmission output flange and passenger axle flange seals are leaking oil, would you recommend genuine Audi seals or other brands, are they both the same part#?
Thanks


Air box much easier to remove and install without MAF sensors.....

[Bigglezworth]

Anything that is responsible for keeping oil in place always gets the OEM part as best possible on my end.

A number of members have removed the MAF's from the air cleaner assembly yes. I remain unclear to this day why the engineers designed it the way they did when clearly it makes more sense to have the MAF's static.

Thanks....

Congratulations on the fix.
