Have owned my brilliant 335i Coupe auto for two years. Happy as Larry, then A month ago I was on 4-lane M-way and floored the accelerator.0 At an illegal speed the engine appeared to cut out, and multiple fault messages showed. Green Flag got me back to dealer who identified an electrical short between main cable and junction box terminal. Junction box and cable replaced (expensively). Yesterday on a single carriageway, overtaking a lorry, the same thing. This could have been extremely dangerous! Was able to pull in to a field entrance. Engine stopped, but ignition still on. Whilst phoning Green Flag I tried starting and car behaved properly. Message said that I could continue my journey at moderate speeds. The sensation when the fault occurred was that the auto transmission had jumped out of gear. Maybe the engine had switched off to prevent it lunching itself. Anyone any ideas? The whole point of 300+ bhp is to be able overtake safely. And I no longer feel safe. Rikkigee
