Hi guys

I went to test drive a 640d a few days ago - it had been at the showroom for approx. 2 weeks, I took it for a test drive (after driving approx 200m down the road a warning light displayed a problem with the drivetrain (can't remember the exact wording)) and went into limp mode

The guy then said most diesels do this at his garage due to being constantly stop-started when moving them around, and would just require a flush due to the DPF

Is this correct or is it likely to be something more serious?

Thanks in advance
