ok let me get the parking brake diagram on this and will get back
i'm still working on this i will have a game plan later this evening!!
sorry for the delay . i need you to check fuse sc1 and sc23 instrument panel end right side make sure they are not blown then check fuses sf 8 and 9 luggage compartment fuse box right side. check with key on if fuses good make sure that there is battery voltage there
please let me know
how about 1 and 23?
on the module i need you to check pins 13, 15, 22 these 3 should be hot and the grounds are pins 24, 28, 30 so check all. the module is located under the battery.
please let me know!!
check it unplugged .
ok with the control module plugged in do you have power on pin 22 with the key on engine running?
the only way is to piggy back a wire with a t pin and then place battery back and then measure at the wire that you placed
yes correct !!! what happens if you place a dirty overlay from the fuse to pin 22? i bet you get communication to the module then
yes correct !!
just be careful!!!! 12v can damage things!!!
Great. Now you need a second person to make sure both brake motors are working. Usually it's the caliper with the motor freezes up.
Let me know
the side where the caliper is not tightening up is an issue and the caliper is frozen mechanically and needs to be replaced with a new brake job . there is a specail procedure where the scan tool is needed to unscrew the caliper totally first then push the piston in with a pliers or c clamp then do the brake change and the caliper change then using the scan tool relearn the position of the pads. that is the only way and do the retraction with the engine running . low voltage is very bad!!!
Yes on 1 and 2 and 3 is a relearn procedure. Sourcing is the dealer
The issue is that the new pads are a lot thicker and you need to open the caliper scan tool them press the piston in so you can get the caliper to fit on the new pad and rotor setup. I do not know of any rebuild kit for the calipers. Plus Audi do not use any rebuild parts of the brake system. Just new
Just checking in to see if you have made progress in repair
