How do I confirm if my BMW 2 Series transmission has failed o r it’s just an electronic fault?

My car won’t shift properly and is stuck in one gear, but no grinding o r leaking is visible. Could this be a sensor o r ECU issue instead of full transmission failure? How can I differentiate between mechanical and electronic faults in Pakistan?

BMW transmissions are heavily electronic. If your car is:

Stuck in limp mode 2nd o r 3rd gear

Shifting erratically but no grinding o r leakage
It’s possible the issue is:

A failed mechatronic control unit

Faulty speed sensors o r transmission solenoids
Get a proper scan with a BMW-compatible diagnostic tool. Many Pakistani garages misdiagnose ECU o r sensor faults as full transmission failures.
