Clearly I have a problem! The best fuel economy I've ever got out of our ZTT CDTi (manual) is 40mpg on gentle motorway cruising at around 70mph.
That's an improvement, by the way, over what it had been doing until Philip had identified that the Pierburg MAF was not functioning at all - and since then, the RoverRon MAFAM has been removed and the MAF replaced with an OEM Bosch item from Eurocarparts.
A great many threads on diesel fuel consumption - can any one give me a route-map for identifying what problem(s) I have with this car?
Many thanks!
