Hi i just had my car upgraded the intercoolers , ap j hooks rotors ,Project mu pads and did all the differential and transmission fluid changes. When the car was brought of the lift they ABS light , VDC off and Traction light were on , i checked the codes with cobb an clear them with no problem. Then today i was with the tuner on the car and after a few runs and braking lights came once again. I tried clearing them but they would not turn off. After a few map changes and on and off cycles to tune the car they went off and later back on again. Has this happended to anyone after brake changes? The code is c1111 which is abs pump? Any help on this will be great... Also the car was even feeling strange in the braking and traction of the car when pressed on hard on the brakes. It feels like if the car braking and traction system is not working properly when the lights are on. Are there any sensors that might be loose , since it came on and off by them self. Also the car was lifted on one side with a jack and a jack stand to be albe to install a y band sensor before tuning. And when we started the car right after the lights came on.
