The emergency brake is not working actually, one of the two cables is shot and rusted so Im just not using it now.
I bet the ABS module need to be replaced, besides the code and the 3 beeps when turning the key, I also get 3 beeps if I take a turn fast. I think I'm gonna have it rebuilt but I don't have a garage and can't work on the car with snow every other day and temperatures in the teens...

I'm gonna try recharging the battery (again, not easy to do if it keeps raining and snowing) and see how the car starts with a fully charged battery and post back.

Thanks!

 

Thanks for the correction. Looks like I was under the wrong vehicle and forgot to log out.

o2 sensors are pretty easy to change, removing the air box assembly gives you plenty of room to work. use an open ended wrench or a o2 sensor specific socket to remove them. Then just unhook the wiring connection.

The problem is that the way the test pipe was installed the o2 sensors are pushed against the engine block or whatever in a way that its impossible to unscrew them without removing the test pipe. And that's something I'm quite nervous about cause Im not clear how I can reach and use a wrench on those bolts...

 

With the weather outside, I don't think you'll be able to get the cat out. Especially since you'll need to get under the car to get to bolts on the back of the cat. This will kind of give you an idea of what I'm talking about (just skip down to the part about taking the cat out.) : :: a4mods.com :: - The Premiere Audi A4 Modification Guide and Pictures Library
