I have this bmw in at the moment, it has had a bit of damage on the osf under the spoiler.

The customer says that ever since he done it it is telling him the outside temp on the dash is 50 degrees farenhieght or -40.

I inspected the damage and found a 2 pin plug loose with the retaining clip missing. I have fitted a new sensor on this but it is making no difference. I had to carve one of the grooves of the plug to make it fit im wondering if this is the wrong plug?
I cant find anything else that could be it. Could anyone tell me if this is the location(at the os spoiler next to the fog light.
