The normally well behaved 320Ci M sport has decided to start using more fuel than normal in the last month or so, normally i would give it longer before i investigate but at the minute 120 miles to half tank isnt great!
I have been keeping track of the MPG for 6 months and the car has averged 27.89 MPG over the 6 months over 350 miles to a tank (normally get 200 to the first half), not to bad i thought. The last full tank fulls have dropped to 25mpg and the current tank i dread to think.
Car was serviced last weekend, and all was fine as it always is. I inspected the car front to back and the only thing i noticed it the rubber sections infront of the fuel filter are badly split, but there was no fuel smell, and there isnt at any time.
No fault codes are present, car still drives abssolutley spot on.
