Disadvantages, breakdowns and problems of manual transmission F20
This is a reliable manual transmission and the main complaints are caused by difficulties when switching
The cause of sticking of the lever is the wear of the backstage bushing or its plastic clip
Another culprit is often a loose gear selection mechanism.
Sometimes the input shaft bearings buzz in the gearbox, but this is only at high mileage
Many owners fill the box with more than 2 liters of oil and it runs quieter
