You could remove the battery cable (live or earth) for at least 5 minutes ... this should reset the ECU but you will have to perform a relearn drive cycle for the car to relearn all the correct setting's ?? a drive cycle is a 20-30 minute drive in normal everyday conditions (ie.) stop and go traffiic etc. and at least one drive on the motorway for 5/10 mins at 50/60 mph do not do not exceed this speed !! hope this helps
