Morning AllBought the car in June and have regularly got 55 mpg doing my commute to work and back.Mid last week I noticed that the fuel remaining indicator in the car had dropped significantly from where it should be with the amount of fuel left in the tankA further 2 fill ups later and my mpg figures are 38 & 41 Mpg on the 2 tanksThe car is well serviced and although I've had a mass of problems with DPF removal, remapping, an egr cooler pipe, wheel bearings, drive shaft and having to replace both rear springs, the car has been running pretty well up to last week.The only significant change I can think of is outside air temp has fallen from the early to mid 20's to 14 & 15c... If the air intake temp sensor was faulty, would that cause the car to run rich and therefor cause this problem ? Has anyone got any other idea's ? Thanks in advance for any help you can give Car has 129k on it
