How do you reset the engine management system on a Peugeuot 307? I notice one person mentioned turning the key fully in the ignition anitclockwise. Excuse my ignorance, but is this fully forward or back with the key in the ignition?

I have never heard of resetting the engine management with the key,if you have had a fault and there is an engine management light on the it will need to go onto a suitable code reader/computer to delete your fault,only when the fault is fixed can this be done or the light will just come on again.
