anyone on here help me out, i have a leon cupra r 225 just had thermostat changed and my car has cut out on me while at a stand still/coming to a stand still, fans didnt seem to come on at all but i know that they work on both slow and fast speed due to testing them through aircon, anyone have any ideas.
Also earlier my friend plugged his bluetooth code reader into my port to read the boost pressure to check if i had a boost leak as it seemed to hesitate upon acceleration, it seemed to be at -9 psi at idle and when accelerating it jumped between 20 and 30 psi and threw out 244bhp as far as i know it is standard but i have only been driving it 3 weeks now just wondering is this normal and if not what could be causing this?:confused:

Cheers for your reply bud, i think i know what is causing it to cut out now, think im gonna have to make a trip to a specialist to have it looked over. I also have a slight niggle in my mind that it has had a dodgy remap put on it from a previous owner but was not told about this when buying.:think:
