I've been looking at my MPG, the DIS has jumped 1.0 from 43.4mpg to 44.4mpg since a replacement air filter and service by mike ... who we both believed the air filter has been in since 2005!! considering it has been serviced before with them, and it should of been replaced..
I get around 450 miles on shell regular diesel, now i've just calculated on the below (quick google) http://www.torquecars.com/tools/uk-mpg-calculator.php and it came up with around 51 MPG, with 450 miles entered, and 40 litres of fuel at 1.15 so that is two different figures so maybe my DIS computer is out somehow? I have reset it many times and it always goes back to around 44MPG, and there is barely traffic here and most of my miles are motorway...
Hi Richard. Sounds like we have similar cars - 75 Tdi Re mapped by Stealth - and I would say your DIS is way out. For motorway driving a rough rule of thumb is 60mph = 70mpg, 70mph = 60mpg, 80mph = 50mpg - that is with a light load.
So if you are truly getting 51mpg then are you driving in the 75/80 mph zone?
As for the DIS, I do not know the answer, is this something that can be reset via Vagcom? Others maybe can answer.
