Ok it's completely random, sometimes it happens, sometimes it doesn't.... It's normally after 24h of not using the car. Key in the ignition, turn to on, dash and radio etc powers on, turn the key to start and nothing, literally nothing, doesn't turn, nothing clicks, nothing happens. Sometimes turning off and back on will let it turn over, other times it takes a few tries. I have replaced the ignition switch thinking it was that, but no difference. Sometimes it happens, sometimes it doesn't its completely random and I can't work out why?! The second it's started, I can turn it off and try again and it works straight away no issues and won't play up again unles I leave the car for over 24hs and sometimes it will go weeks without issues.... Sorry if I'm being vague. Starter does start the engine straight away no extra turning over or laboured turning over? I have done vag com fault tests and only thing that comes up is engine mount resistor out of range. Could it be an imobaliser issue? At other ideas?
