It's not a hardware problem , there are cars out there which have been fine .. Renault use a very similar U shaped cooler . It is vital the software is kept up to date , it seems to be updated at least once a month at the moment ! The EGR is being used about 70% more of the time than the euro 5 models to comply with euro 6 . There is a flap which can by pass the cooler so maybe they are trying to use this function more . The EGR valve has been improved which has helped a lot .
