On board computer consumption readings
Every now and then the on board computer consumption readings go crazy on my 159 1.9 jtdm, showing really unbelievable 20l/100km (12 mpg!) while doing 40 kmh in 3rd. If I even touch the gas pedal, it goes all the way up to a 50l/100km (5 mpg). The only thing that cures it is, pull over, turn off the engine, then turn on again and everything is back to normal. Anyone had that?
BTW, overall consumption seems normal, i get around 700km per tank doing mostly short urban runs.
