Aygo 1 Starts but does not idle or rev

Good to hear you found the likely problem area. Perhaps the reason it won't adopt the key is because something has failed, maybe the antenna ring or the key itself? I think you'll need to get it looked at by an automotive locksmith, but it's worth trying with the spare or disconnecting the Battery for half an hour first. Don't think it will help but worth a try.

It needs to be done with a mid to high-end scan tool or techstream

I take you have cleared the code then remove the key if B2799 is present in will not start

I don’t know much about these cars other than my daughter has one she got recently

But, in most cars, there’s a fuel filter in the tank and another near the fuel rail

I’m plumping for the filter near the rail

It’s been confirmed as a problem with the IMMO box / ECU. It’s going off for flashing today.

Hi,

My daughters Aygo 2007 will not start and run. It had not been driven for a couple of weeks and now when trying to start it:

- Fuel pump can be heard priming

- Turning ignition, it fires up but does not continue to run or idle

- even dabbing the accelerator when staring does not seem to push it further. 
 

Battery seems very healthy in terms of the starter and I’ve also charged it fully just in case. 
 

Any ideas ?

Have you had any problems with water inside the car? In that case i know what the problem is👍
