My 65 plate citroen c4 SOMETIMES will not start first thing in the morning

[Nick1950]

Hi im a noobie to Citroen. My 65 plate Citroen C4 picasso vtr+blue hair auto will not start off the push button, MOST mornings. The doors un lock, the mirrors sometimes open. No dashboard lights at all.
If I persevere the car will eventually start after maybe 10/12 attempts. Dash lights come on, mirrors open and the engine fires up. I've had a new battery fitted, new key fob battery and the car has had a full service, but still the problem persists. Any ideas, PLEASE.

Hi and welcome. VTR+ Blue 'Hair' that's a new one on me, I think you may mean HDi.

What you really need is to get it diagnosed properly. These cars are full of electronics and you don't want to be replacing parts unnecessarily as you've found out so far. These cars need somebody with a professional level diagnostic tool - generic code readers are highly unlikely to read all the non-generic constructor codes. I would in this case get a dealer to diagnose it as for the sake of £90 you should have a proper diagnosis of the faults and a good idea of the issue and cost to resolve. Driving round from garage to garage may not be a good idea and can be a false economy.
