So I was cruising around in 2nd gear in P400 and punched it and all of a sudden the MDM light came on. I thought I had mistakenly hit the M button but I would've remembered the throttle response kicking in in P500S. I hit the M button then turned off M mode and the light was gone. I'm chalking it up to a weird electrical quirk but was wondering if anyone else has experienced this.

Never happened to me.

Can you please check the settings for your M button.

 

[SunnyD]

Checked and my M button is set for P500S, S5, MDM, EDC Sport. I'll report back if it happens again.

Maybe..

Maybe you or something in your car accidentally bumped the MDM button? This would just put the car in MDM mode, not "M" mode.
