Is it ossible to change the speedometer to show km/h instead of mph? I do quite a bit of driving abroad and my last few cars have had both shown on the dashboard display, but the TDV8 4.4 only shows mph. I see there's a facility to change fuel consumption figures from mpg to miles per litre and so on. Any ideas?

Be careful. On the P38A the units are stored separately to the numeric value so what goes on in km does not get converted to miles but stays at the higher number.
 
Change the fuel computer to L/100km and a KM/H speedo appears in the bottom of the speedo. It's in the handbook.
I've coded the MPH one input mine full time but you can see where it is here
