Earlier today I attempted to do a few software tweaks to my '05 A8L. I was able to remove the seatbelt chime, but all other attempted tweaks failed. I tried to re-code my 6 speed transmission to a sport setting, but the software keeps telling me the code is too high (trying to go from an 02 setting to a 12 setting). Then, when I tried to lower the car 20mm, it would allow me to enter the codes, but the car wouldn't actually respond to the new setting. Now I have a 'headlight range control error' warning on my dash, and the adjustable suspension feature isn't available anymore. I followed the instructions on the Ross Tech site, but I'm a little stumped at this point.

Anyone have any suggestions?

 

Start by posting an Auto-Scan so we can see what installed in the car and what fault are stored.

That is not a complete autoscan. That is a control module scan.

Please go to [Autoscan], choose the A8 (4E) from the drop down list, and click [Start]. Let the scan run through all the modules pulling in all the data.

Post the result here by pressing the [Copy] button and pasting the information into the forum block.
