I recently acquired a 2007 1.4 Mini One from a family member who mentioned at the time that there had been an issue with the vehicle stalling when stationary. He’d taken it to the garage he purchased it from (Audi/VW specialists) who were unable to identify the cause. It hadn’t occurred for a few weeks after that but then today just under two weeks since I started driving it, the engine cut out at a roundabout. It was so quiet I didn’t even realise. I re-stared it & it occurred again before I could even put any revs on & then a third time, no spluttering as though I’d simply turned the engine off. I drove a couple of miles & stopped at some lights & it happened again, five times
Looking back I see the issue has been raised before going back to 2007 but wondered if anyone had a definitive answer as most posts report the dealer couldn’t identify an issue.
