Hi I am in need of coding for a S8 that has ACC fitted.

I need coding info for both engine ecu's and instrument cluster

If you have an S8 with ACC and VCDS I would be very grateful if you could post up or pm me a recent vcds scan.

Thanks in advance

I have W12 so can't help, but if you need to code ECU's, how? They are twinned and have to be done in parallel apparently. They cross check each other real time and VCDS can only access one at a time. If you are just checking existing coding to see if correct, then I get it.

This might be helpful as it shows what to code.

Well thats something I didn't know and hope it doesnt become a problem.

I have fitted the stalk for distance regulation but have yet to fit cluster and radar sensor, and now both ecu's for engine report a fault saying incorrect coding.

Trouble is the S8 does not have any label files so I am unable to use long coding helper to figure out what coding is needed once the other parts are in.

What year is your S8? Here in the US I thought all S8's had the correct cluster(wide display).

You are indeed correct all s8 do have a wide dis, but there is different versions, the biggest difference is the one for acc has extra PCb and different software to show the ring of LEDs for the speed setting etc

It's further complicated by different features like needle sweep on start up

Older clusters use short coding and I am of the understanding that the newer clusters that's in the facelift cars use long coding

Hence the need of a Autoscan from a facelift car with Acc

My car is 2007 but I am fitting the newest revision of cluster for acc retrofit

Thanks

Makes sense. Thanks for sharing that as I now know something I didn't know before. I just assumed all wide displays were the same.

I have managed to find my way in the dark and it's now all working.

Good to hear! Mine is still not functional. I am supposed to go to Audi next weekend to have it calibrated.

Do you have VCDS?
