I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.if the transmission light is on, there should be a fault that can be read with appropriare diagnostic equipment
if the shop you are using can't read a code, they likely dont have the proper equipment
your symptoms suggest a problem with the slector switch or possibly an internal fluid issue.
a proper fault scan and test plan on a factory BMW tool will be required to verify.
