2013 Skoda Superb 2.0 TDI, 147k miles. 

 

Normal behaviour: as I drive, the average fuel consumption changes quite quickly, starting out around 25mpg and typically going up to about 35 if I'm zipping around a city, or it will gradually make its way up to about 53mpg if I have a long motorway drive. 

The other day I was driving and noticed the emissions control light had appeared on the dash. I kept an eye on it, and after leaving it overnight and driving the next day, the light had disappeared. However ever since then my average fuel consumption is stuck at between 44.9mpg and 45mpg exactly. It just doesn't seem to change at all, I could be revving the engine around a carpark or slowly cruising down a long straight road, it's stuck there. 

The only other thing that changed is I refuelled, but I don't think it's that (since the mpg literally doesn't change). 

Is this a computer fault do you think? 

Have you selected reading 2 - this is long term mpg and will change more slowly - you can tell by scrolling through the options and see journey time and miles covered?  You can swap between trip and longer term by pressing the right-hand scroll wheel

I did not know this! I will try this in a couple of hours when I go for lunch and report back. 

pressing that scroll wheel usually takes me to the options but I'm guessing there's a trick to it - I'll fiddle around and let you know. 

you need to be in MFD, and them the scroll wheel lists things like oil temp, mpg, consumption, journey time, miles covered, etc. top right in the MFD is a number 1 or number 2 - if 2 you are in the long term trip meter and 1 is the current trip that is 0 miles, 0 mpg etc when you go out first thing in the morning.

You were right, thank you so much. 

Glad you’re all sorted 👍

Ps love Pinky & the Brain, which I assume yr forum name is based on?
