what symptoms did you have that required its replacement?
The engine management light came on, and the dashboard told me to go to the workshop. As I was only a couple of kilometres from the workshop, and leaving on a 1600km round trip the next day, I took it in. The stepper motor was blowing a fuse, and they replaced it. To give credit where it's due, they sourced the part and fitted it the same day, with no notice or warning, and the service manager gave me his car to use for the day.
why do you believe it was not faulty?
The next day, 400km from home, the starter motor stopped working. It too was blowing fuses, and as the two are near each other physically, but not functionally, I suspect that the problem was more likely to have been a wiring issue than both motors failling within 24 hours of each other.
The agents wanted to replace the starter motor too, but I refused to pay for it. Eventually they offered to have it overhaulled (at a price that you can replace it for) and again I refused. I eventually got the service manager to agree that they would not charge me for the overhaul if it didn't fix the problem. They never reported back, but I was only charged for labour for removal and refitting of the starter motor, so it's a safe bet that it still blew fuses after being overhaulled.
