I've just driven over 300 miles today and for the last 100 miles or so the MPG has shown 39.9mpg despite varied driving. Is this the limit for the OBC? The only time I've ever seen 40mpg is on start-up. It's not stuck as it dropped to 39.2 for the last bit of town driving
Guys
How do I change the OBC from KPH to MPH on my C180 SE coupe?? Would appreciate your replies as I panic driving past speed cameras thinking that I have been going too fast!!!!!!!!!
Thanks
The overhead OBC in my ML has always read (annoyingly) in kph. However, the other day it was reading in MPH but has now reverted back to KPH????
Does anyone know how to change it to read MPH?
Thanks.
