Very cool- thanks for posting!

The last 7 digits of my VIN includes a letter (C123456) Do I count the C as a 3, or do I ignore it?

I believe it's the last 5 digits of your VIN (in your case, with a VIN of "23456" the total would be 20. you add the 2+0 again for a code of "2" (note: it might have been "20" but i think I added the last 2 digits again to come up with a single digit number). Below is another description someone posted months ago. I used it to reset my mileage cal factor from 1000 to 1045 (Car used to over-estimate my mileage by 4.5%). I'm now within .1 mpg of the actual value....

Trip computer true MPG adjustment
Does your trip computer over estimate your true MPG?
If so, I found this piece of information on another forum that could help:
You could if you wanted use the correction factor in the hidden menu to make the quoted MPG the same as the actual MPG.
here's how:
1. Hold down the odometer reset button and turn the ignition on by pushing start/stop button.
2. Release the odometer reset button, and you should see a menu of 4 items on the dashboard. From here on, use the odo-reset button to advance to the next entry through a short press, and to select through a long press.
3. Choose the one that says Unlock through the above, which will take you to a passkey screen. Your passkey is the sum of the last 5 digits of your VIN. Increment the two-digit number until you get to it, and with the long press of the odo button, select it.
4.then scroll down to correction factor and modify it from 1000 to whatever you require

My car claimed more mpg than it was actually delivering by about 6%. I changed the 1000 to 1060 and it now seems about right.
It did take me a few goes at getting it right , but I much prefer seeing the correct MPG displayed.
If your trip computer reads higher than true figures worked out, make the correction over 1,000. If your trip under reads (very rare!!!), make the correction number under 1,000

Just tried (on my Canadian 2011 550xi) - add last 5 digits - works like a charm.
Some nice info to spend time on the long red lights or traffic jams
