Fuel economy gauge on 2012 1.6dci puredrive

Post by Newbydooby » Thu Jul 16, 2020 6:23 pm

Got some much appreciated advice prior to taking the plunge on my first ever Qashqai today, she is sitting on my drive for the first time tonight and I am very happy.

Just on fuel economy I got a bit of a fright when I had a play just after taking delivery as the fuel economy gauge prior to me driving anywhere had a read out of 27mpg which shocked me a bit as I can't imagine the circumstances in which this car even round town would register so low?

Anyway after a reset and about 20 miles of ordinary urban driving, this evening, I am getting a reading of 45mpg which is much more like I was hoping for.

Just wondering, based on experience, how accurate this gauge actually is? Is my 45mpg reading likely to be very roughly correct?

Not a direct comparison since my car was a J11 petrol but I found the onboard computer very accurate. Over 10,300 miles the gauge was on average only pessimistic by 0.4. Curiously top-ups 3, 5 and 7 were most pessimistic and it settled down after that with top-up 27 being most optimistic by 0.9mpg and top-up 27 being most pessimistic at -1.2mpg ,

My Fabia previously was 22% out (actually an uncorrectable firmware issue ) and my present car is 4.2mpg on average too optimistic.

I have the 1.6 diesel auto and the gauge on economy 2 shows 40.8mpg yet economy 1 rarely drops below 45mpg which is more the figure I get between top ups with a best over 60mpg. Mine is a 2014 J11
