Fault Code A690

Post by GELewis » Fri Jun 10, 2022 7:32 pm

My 2012 e89 shows a full code A690 - which appears to be a "microswitch, rear-end module closed, left." Does anyone know where this microswitch is located?

That's a tough question.

I normally use real OEM (link to a sliding roof model from 2012 - https://www.realoem.com/bmw/enUS/showpa ... Id=54_0398)

The part you are looking for is "6" I believe.

If this drawing shows me anything it seems to be located around the part 2 "Coupling lock, left", so I think you need to take some covers in the trunk. My car is in the garage so can't help you just now.
