OBC inaccuracy

Having just checked the MPG (brim to brim) compared to the OBC, the OBC is about 12% optimistic - no surprise there. However, it got me wondering whether everything over reads by the same amount, i.e. odometer, speedometer (which I know reads fast)? I understand that it can be corrected?

Yes (on a D4) you can correct the mpg reading to make it more accurate using an IID tool and probably also with other diagnostic tools capable of editing the ccf.

That's very kind of you Robbie, thank you. I'll consult my diary (got a busy few weeks coming up with THAT event!), and drop you a line. By the way, I got the bits for the remote FBH operation, which works an absolute treat! I'll be in touch.
