MPG / Fuel Used rapidly changing.
I've got a Grand Scenic 1.9 dci on 05 plates.
Before I contact a garage for an investigation job. I thought I would ask here....
Whilst driving home from work I've often got the MPG displayed. A quick glance now and then might reveal its going up.
Took a look and noticed it had gone up alot
So another glance and noticed it changing all the time. Hmm thats not right me thinks. 36.5 ... 37 ... 43 .. Whats going on. Then it when more crazy and started jumping both up and down in large amounts. Scrolled through the display to see that the fuel used display was zero.
At home I reset the MPG display and went for a quick drive. Thought it was fixed, but it soon went back to being a random number generator for the MPG. The Range display drops about 1 mile every second. I guess it too is being affected by whatever fault is causing the display problems.
Anyway story over. Any thoughts. Loose connection ?. Fuel management issue ?. Something mechanical ? Buy another car ?
Thankyou in advance.
