When the control module goes bad you cant even get a code, right? I'll have to get my Vag back from a friend before I can check it. Would that make my e-brake light up as well?

Is the relay easy to change? Just pop it out and pop the new one in?

Default It's probably the controller

My shop says it quite common. About $750 to fix.

Default no dice

I have the same problem, one of them is solid, and one blinks? i forget which one is which, vag won't bring it up, cause it can't communicate with the module. The module is prbably bad, only other thing it could be is a speed sensor....... it's not bad to change, there is a how to, in the tech articles, hands down the bst thing to do is send it out to get rebuilt, you can get it rebuilt for 150 with a lifetime warentee........audi will charge you 800 for a new one and labor, let me know if you have questions

Default Both lights are solid. They were pulling codes from the controller though

So thats whats making me think the controller is fine but since its such a common issue I dont know. I'll have to Vag it again and see exactly what it says

Default that's interesting........

that's interesting.......i believe my abs is solid and my break light blinks.....don't go to a dealer, they charge huge bucks for the diagnosis, my guess is it could be a speed sensor? also, if the abs pump went.......you could get a vag from the controller, right?
