Before requesting help, just look up the codes, please.

Look up Ross-tech diagnostic codes on their website.

Why did you start a new thread? All these popped up after you unplugged the tranny fuse and then disconnected the battery in bad attempt to fix the limp mode. Clear them all and see if limp mode goes away. Re-post with whatever codes come back.

At the very least you need a Audi specific code reader like this one: http://www.ecstuning.com/Audi-B5_A4-..._Tools/ES9951/ Better would be a Ebay generic VAG-COM cable + laptop + Ross Tech free software. Best would be the real deal Ross Tech cable and software.

Also get your ABS module fixed. Very common problem. I had mine done by BBA reman for $60.

I made the new thread because I am a moron......seriously. Secondly, I cleared the codes, no luck. I am taking Technologic's advice and taking it to the Audi dealer tomorrow.

Did all of the codes reappear after you cleared them? Or only some, or none at all?
