Hi wondered if anyone could advise, my friend has recently swapped his steering wheel control model on his 2007 A3 for the highline one in order to retrofit the MFSW. All has gone well and working apart from now he has his ABS light, and ESP light stuck on. We've taken the car for numirous drives and non of the lights have gone out. Intrestingly when we plug VCDS and go into the ABS control module the handbrake warning light comes on, flashes and beeps constantly. The fault codes read Angle Sensor even though we have completed the calibration???
