I've had my Td4 Auto for just over 6 months with no problems & it is a brilliant car to drive. Could do with more power though & that's after my egr bypass & Roverron box fitted. Don't forget to change your crankcase breather filter/valve assembly. A search on crankcase breather wil give all the info.
of course - if yu had one of those loverly pretenders, yu wouldnt have that problem.
EGR bypass and roverron box are on my to do list
