The long term mpg readout on my Octavia has suddenly started acting funny - usually it’s the most stable of the 3 options, from start, since refuelling, and long term.  But today, it’s fluctuating, almost (but not in sync with) the instant readout.  Now it’s reading around the late 50s/early 60s mark.  Ok, over the last 3 days I have been adding the miles, but the other 2 readouts aren’t as high.

 

 

EDIT:  I’ve now reset it, so we’ll see in the next day or so…

It could have been that it had coincidentally reset itself after going over the 1000 miles or whatever the reset threshold is.

 

Whenever I suspect my readings I look to see how many miles have been recorded.

 

Now I'm wondering if it only resets after a journey has been completed?

 

These things are sent to exercise our grey matter!

Thanks JR, it seems OK since I reset it.

 

Apologies for delay in acknowledgment, most of our town has been without Wi-Fi since Sunday - rats had chewed through a main fibre supply line…
