The first 3 months i have owned this car has been a nightmare.The care has hardly ever been out of limp mode and all the dealers want to do is throw part after part at it.I had had enough of the car after 3 months of crap with it i really was thinking of burning it..it was that bad.After googleing “can limp mode be deactivated”i found andy ecu flash.he drove to my house plugged into the diagnostic port turned all the antipollution crap off which after research nearly all modern day peugeot and citroen cars are havin the same problem with.As a result the car has never been better and i went for the option off havin the car mapped for better power and fuel economy.The car has loads more torque and the fuel figures are much better.The peugeot 807 has a bad name for fuel economy but i drove to manchester the day after andy had done his magic and averaged 44.5 mpg which this car has never seen.So take it from me ITS WELL WORTH IT i am very happy with his work if you want reasurance email me if you like wild879@btinternet.com .cheers again andy 🙂
