Link to micro switch: amzn.to/4dzpuhe
This is a common problem for the touring series, 3 and 5 series when the glass hatch stops working due to moisture getting in to the micro switch and causing it to stop working.
My dealer would charge me 150 euro to get this switch changed but you can easily buy one for like 10 dollars and then change it yourself now that you can open the hatch. Or change out the diversity antenna which also includes opening the glass hatch.
