haha i've had my "front wheel speed sensor fault" code since i've had the car. I did a shadowing at mercedes, and there was a tech that was previously an audi tech and he said it happens a lot. Its not a PROBLEM, its just annoying when I start driving and it beeps the **** out of my ears.

Just means I have to turn the system up louder.

 

its the abs module. yay expensive fix.

I have the same exact problem, solid ABS light with blinking e-brake light next to it. After reading that article I freaked out from the $1950 repair cost!

I'll update this thread when I hear back from them.

 

you can just purchase the abs module (electronic portion) $500+

I just went to my mechanic and he estimated a 3hr job. From the DIY, it seems pretty basic.

 

I know you're just talking about the electronic portion of the module, but what's the difference between the two pump assemblies on that site? One is close to $700 more than the other.

 

^ it appears that the more expensive one is for cars with ESP.
