^^ The car starts for a split second then dies. When I push the start button again all is good.
It seems to randomly happen (once every 15 or so starts) when I have to fill up with Shell V-power and when the car has been off overnight. I've wasted money a few times at BMW and an independent trying to diagnose the problem but they keep assuring me the cars fine.
I've accepted now it may be normal for the car to sometimes take a few goes to start.. Shell V-Power being the cause is probably just in my head, just like the PBX feeling like it sometimes switching off lol
