Mondeo MK4 Fuel Computer Strange Behaviour

Recommended Posts

I have 2013 Mondeo 2.0TDCI Titanium X Estate

Last week I had the DPF cleaned/flushed and a new vaporiser fitted

Now my fuel computer no longer gives me, average mpg, instant mpg or miles left in the tank. Everything else works OK.

I start the car and things appear normal and with a couple of minutes the three above functions disappear as if they have reset themselves and each one just shows --- -

Any advice would be most welcome

I would suspect damaged wiring. It maybe it has lost the fuel level signal from the tank sender unit or it has a problem with an ABS sensor. For the system to work it needs the fuel level, distance traveled and speed.

Use FORScan and you will probably find a DTC has been stored.
