Hello everybody, I am a new BMW owner and new to the forum. I have bought a 2006 E91 320D M Sport Touring with 19K on the clock... very nice. My one disappointment is the fuel consumption. The published figures for this model are 62.9 extra urban and 49.6 combined. Now, I realise that, in practice, it is virtually impossible to achieve these figures but on a long run of 300 miles, nearly all motorway, the best I can get is 38.1. That falls a long way short of the expectations set by the figures. There is one other symptom ... If I have to slow down on a long hill like the one on the M40 near High Wycombe I have to change down to 4th to resume my speed again. I.E it seems a bit short on torque. I explained all this to the main dealer and BMW customer services and booked it in for a diagnostic. The result was - no fault found, no error codes, reset the trip after each journey for a more accurate reading, thank you very much that'll be £35 quid please. After reading this forum I phoned Simon at E-maps who was very helpful. His immediate response was "sounds like a classic airflow sensor problem, did they drive the car?" They didn't. He said the only way to test for this is to drive the car with the dianostics running. So, back to the dealer. He has agreed to do this tomorrow (Wednesday) but with a warning that it might cost me another £35 quid if no fault is found. I would like to ask the forum if you feel there is a genuine problem here or am I being picky? I would particularly like to hear from owners of similar cars as to what mpg they are getting. Mine is a 163bhp model and, on motoways, I drive above the limit but I don't thrash it. Any help you can provide will be much appreciated.
