Evening all, trying to get the wife's mokka through it's MOT. It has decided it doesn't want the rear Fog lights to work it's not the bulbs and I have literally pulled/checked every single fuse! Only got 6.4 volts coming from the wire behind fog light switch! Is this just a signal for bcm or should it be 12v? I have a crappy feeling the bcm is faulty any help or advice is hugely appreciated,thank you.
