Hi all
My 330d fuel economy has deteriorated, I have recently changed the egr and main stats and these helped a little and certainly improved the running temperature.
I also recent replaced the air filter which made a good difference to the drivability of the car.
So I bought and installed appropriate cable and INPA and my air mass reading is 1650
well outside the recommended range.
There was a number of codes also logged, including the air flow meter input air sensor
My question is what could cause this, is it likely to be a faulty maf?
Or is there out easier to check options than having to strip out half the engine to get to the maf!!
Cheers
Steve
