I have a 2012 MCS - I popped into the hidden service menu here: https://www.northamericanmotoring.co...on-tach-2.html and managed to screw up the fuel consumption correction in screen 20. Menu 20 as soon as you go into it, it starts ticking up the values for the consumption adjustment. Apparently doing the reset in screen 21 doesn't revert any accidental changes made to the fuel consumption correction. So! I have a favor to ask:

Anybody out there with a 2012 MCS willing to read me what their values are for their fuel consumption values are for their car?

Right now my car thinks it's getting 50MPG, when I was averaging 28.5. before.

 

Oh, and here's a video of me flipping through most of the menu screens in the service menu:

Hi, I noticed in your video that your consumption value was 700. My experience is with several BMWs and the factory set default value is 1000. So if you can get it back to there you should be good. If like my MCS, you need to correct for a very optimistic mpg reading you'll need to go above 1000. I.E. if you want a 20% correction you enter 1200. Anyway can you help with mine? It is a 2009 MCS and I can't seem to get into the same options as in your video. I think I'll need more specifics as to button pushing. I tried to update my brake wear indications and they won't reset. Its possible that's due to wear of the sensors but I am not sure I am pushing the buttons correctly. Thanks

 

Warewolf, thanks for posting the info and video above. It inspired me to go out and finally figure out how to make the changes I needed to my MPG value. Look at my post that I just issued today for a step by step procedure for Fuel Consumption (MPG) Correction. Let us know how you make out with your Factor.
