Hi All. Anyone can help? My 2011 A1 122hp, no auto hold function.
My A1 has no fault/warning light on. But it's hill hold assist is not functioning at most of time. Sometimes, it functions when stopping at traffic light on a hill but the car roll back when I release brake pedal that means hill hold assist not functioning after tens seconds.
I had checked the computer record of my A1 but no error/fault code is found.
It is an odd problem. Anyone know what happening with my A1? Need to replace the sensor of braking system? Thanks so much!
