Have you had the cars PCM (computer) reset to clear the fault codes and get the vehicle out of limp mode?

Have tryed to clear the codes with my reader but the fault is still present. Is there any other way of resetting the ecu?

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
