I have replaced my power fold mirror on my mk6 golf with a non genuine one. If I turn the knob to fold the mirrors in, one folds in and the other folds out! Also when the replacement folds out it's not 'locked' in place so it's obviously not right.
I got a refund and tried another supplier but it's the same make and has the same problem. I did take it to a local Ford garage and they said it was the mirror at fault and it didn't need coding in or anything. I just wanted to check incase I'm missing something or is it just faulty non-genuine parts?
