So what's unusual about that,surely unless you only put a tiny amount in it'll show a range of 72 or any figure greater or lower depending on how much fuel you put in.
The fuel gauge was pretty low, below the quarter mark I think. The range on the fuel computer stated I had 72 miles worth of fuel left. I did just over 72 miles, without putting any more fuel in and didn't run out.
The CID had just been reconfigured from the 2.2dti which it came from, to 3.2 spec which my car is. When The Boy saw the fuel gauge and the range showing 72 miles, he voiced the opinion that it may take a few miles for the car to adjust the figures, as he didn't believe that what was showing on the fuel gauge would equate to 72 miles of driving.
I hope its all clear now ?
