1.5dci wont start straight after switch off - Injector Fault

[JAMESBRANTON]

Hi

I have a 1.5dci megane 2 hatch. If the engine has just stopped and I try to restart (i.e. after a stall) it can take several cranks before it fires up. It may be connected but when I accelerate hard the 'Injector Fault' message appears. I have changed the fuel filter for a genuine one, no change. I am guessing air in system but have not won the Euro Lottery to fund Renault to play guessing games and effectively changing every engine management part unit they stumble on a fix.

Thanks

James
