i also get this problem. My electrician says it has something to do with voltage/crank time or something like that. Interesting, when the engine is warm say after a drive and i later go to autostart it than there is no problems but when its cold, no chance. It just gives up after the third try. btw manually starting the car cold, do you have to give it a bit of gas? if so, maybe chance the spark plugs and this might help it.
