Suprised to find the voltage not swinging up and down as before. So have to retract:
'To sum it up volts on my LX ALWAYS rises slightly on rev increase and vice versa. On the zetec its exactly opposite, always falling on increase in revs and rising on deceleration, by quite a significant amount ie down to 13.8 or so from at or near 15V. '
So in a car with a good battery I'm suspecting the SOC cycle
might be slower than I thought, will keep wasting time on it and see.
Forscan on android shows 6 digit figures like 163750 while cranking and 473375 while cruising. Units are described as 'Amper'. Can't makes sense of it.
stefcio007 where did you find the information that the BMS must be reset?
Do you know of information specific to MY2011 TDCi Mondeo?
What did you use to check the current? Thanks.

I use Torque (Android and an OBD reader) with custom PIDs, I checked Mondeo and Focus forums and just tried each PID to see if they worked in my car.
BMS reset is listed as a service procedure in ForScan (used PC version) and in Ford IDS. I assume it's the same for the Mondeo. Do you have an extra sensor on the negative terminal cable attached to the battery? If you do then you have a BMS.
