It is a noticable change as I noted a couple of years back. But I would like to know exactly what it does. Does it just change the gear shift points in Drive or does it also change the Sport settings?( I cant really detect any difference in Sport). Does it change fuel/air settings or is it confined to gearbox setup?

Oi!! Steady on!
Commodores aren't that bad! I came from them into the Audi camp (and have absolutely no intention of going back).
They suffer a little from the practices of their parent company, but generally hold together ok and have easy going torquey engines.
Easier to work on than large Audi's too

One of the things that makes it easier to work on is the lack of corrosion as there isnt the amount of rain/salt on the roads as there is in the West of Scotland. To be fair, the Buick engine used seems pretty bomb-proof and there arnt too many "black boxes" so most things seem DIY'able.

Wondering if 00111 or 00131 would do me any good?

Would there be any risk in trying any of those codes?
Sometimes resurrection of old threads isn't such a bad thing!
Just changed coding on the S8 from 00001 to 00011 and it makes a significant difference to the car.
Haven't managed to play with the tiptronic yet. I now need an excuse for a bit of spirited driving on a nice twisty road!

After you're familiar with that try 00111 and see what that does.

How would you explain the difference in feel between 00001 and 00011?
(I've only ever had 00101 and 00111 and I thought S8's were normally 001xx anyway not 000xx )

I've been thinking of doing this with mine soon, I've noticed that when the wife is driving (mostly around town), it seems to use more fuel. I think it's because it's holding 3rd until nearly 35mph and not changing to 4th (whereas I usually drive in tip mode).

Having looked at the link in the OP www.audipages.com it looks like the xxx1x is de-activating the dynamic shift program (DSP).

There is a line that says "The dynamic index number controls how the transmission shifts. If your A8 has the stock transmission coding of 00002, then it sums dynamic index number closer to "old man mode" versus "sport mode"." So it also looks like the xxx1x is activating the "Sport Mode" which surely should be activated in an S8 by default?

Adding in that extra 1 at 00X1X made rather subtle changes for me.
It seemed to be more responsive to change of driving style though that's difficult to measure.
It DEFINITELY would change up to higher gears when driven gently or on cruise control at local road speeds whereas before it was often stuck needlessly at higher revs when "pottering".
The latter behaviour was noticeable and made "wafting along" feel better too.

My car is a '00 FL but all the build stickers in the car suggest it was built around Oct'99 so it may be one of the first FL's off the line?
The gearbox is 5 speed and it has a fly by wire throttle so it's certainly a FL.
Wouldn't accept 00111 at all.
I had been trying 00131 and a few other codes from the various links in this thread but it wouldn't accept anything other than 00011

Haven't really played with it much, it's holding 2-3, 3-4 and 4-5 in relaxed driving longer and much longer in harder acceleration.
Downshifts coming in to a roundabout without coming to a full stop are much smoother. With 00001 coding the car would have tended to drop in to first even when still rolling so accelerating away tended to be lumpy/jerky. It's holding 2nd now.

I need a good Ulster 'A' road to try the kickdown and play with the tiptronic a bit but that will have to wait a couple of days as I'm off to Birmingham on business.

Thanks for that, intriguing, both my PF (1998 build) and FL (2002 build) took the 00111 (previously 00101) coding with pretty much the same effect.

Looks like 00x1x is the key bit to try.
