Can anyone help please? I have had a full service done on my audi a6 2015 and the break pads sensor came up after 2 days the sensor turned off and the engine light came on. Went to a garage they scanned the car and it came up with maf sensor, so i got that replaced and they removed the engine light but after 10-15miles of driving it came back on, went again to the garage and same thing came up maf sensor.
