I have a series 1 and a few months ago the drive train light came up. We took it to BMW dealership and they said it could be the clutch. They wanted us to pay £600 to investigate as I think they had to remove the engine or something. If it was the clutch that needed replacing we had to pay the full amount as not on warranty. However, if it turned out to be something that was covered on warranty we wouldn't need to pay the £600 and parts. The Car is only 3 years old with 42000 miles. We are leasing it and its due to go back in 3 months. However, can't return it with the dash light on. Going to cost us a lot of money but unsure what to do. Has anyone else had problems with 2017 drive train / clutch problems. My husband and I are in our 40s and don't drive mad, and also never had an issue with wearing the clutch out early before.
