Hi just read the earlier post properly [my fault] if its the 3.0 engine and is not running Adblue you should not get the problem I described the v engines suffer more with EGR valves and swirl flap failure, the way to combat this is buy a bottle of Wynns EGR cleaner and add that to the tank every month, with regard to upcoming faults it may be wise to get a scanner such as OBD Eleven so even if there is no EML that will tell you about oncoming faults, thats how I discovered the p2002 fault for the cooler, its worth scanning every couple of months so you can clear all the one time only faults these cars throw up which keeps the various control modules clear, all the other problems I mentioned will still apply, auto gearboxes need religious oil and filter changes every 40k otherwise the oil becomes acidic/burnt and will terminate the box, manuals are more forgiving with just an oil change every 60k.
