The emmisons light came on the car a while ago the car is a 2005 audi a3 2.0tdi. looking through the internet most forums said that it was a common fault with the dash light on this year and model so didnt really worry to much. The car went to the garage for the cam belt change, whilst there i asked the garage to put it on the machine. It came up with the following faults 19557 swirl flap motor, open circuit to ground 19558 swirl flap, no signal Could someone please translate what this means! and will it be costly to rectify?
