G37x and VDC
Exactly what is the VDC switch suppose to do on my 2009 G37x?
I just turned 4000 miles on the odometer, and under many different conditions
I am unable to tell any difference with VDC turned on or off.
Thanks,
Mac

VDC off removes all computer assistance and pretty much lets you launch and stuff. With your AWD, I don't think it makes a difference because you keep handling no matter what.

i still have the "slip" light flashing on occasion even when the vdc is off. seems to apply the brakes, but not sure. anyone give me any insight on what happens when the SLIP light flashes? the manual is not real helpful on that. ...

Keep it on unless you're at the track.

Another non-screwing-around usage for disabling VDC is for when you are stuck in the snow. I bought this RWD car with the sport summer tires last november and didn't have the will to spend more $$$ on snow tires & rims right away -- figured I'd wait til next year. Little did I know the D.C. area would have record snowfall totals this past winter season; like 10X the amount we normally get. So I learned my lesson.
Anyway, the point was, sometimes disabling VDC in that situation helps allow your rear wheels to spin more rather than applying braking which might help you get out of the snow & ice you are stuck in. Or something like that. Not really sure if it made a difference or not. But the slip light came on whether VDC was on or off.

[QUOTE=efuseakay;2898401]Nah... meant for the OP, who didn't seem to quite understand what VDC was... 
You're mistaken. The original poster knows what VDC is.
My inquiry was around noticing any discernable difference under various conditions with the switch in either position.

When you turn off the VDC, the Traction Control turns off and the Stability Control turns off as well. What remains are the Intelligent AWD system, the ABS, and the Active Brake Limited Slip which transfers power to the adjacent wheel on the same axle by applying the brake on that one slipping wheel should the computer detects slippage.
Therefore, when you turn off the VDC, you can spin the wheels to get you out of deep snow or dirt (or to burn rubber at the lights) because the Traction Control is off. You can drift your car because the Stability System is off (for track uses). However, you do not notice it that much with the x due to its higher level of forward traction with intelligent AWD. Lastly, the Active Brake Limited Slip is always on to ensure that both your wheels on the same axle are optimizing traction while allowing you to spin the wheels. So turning the VDC off is not turning off the "computer". It's meant for you to get the best traction to get yourself out of deep snow, dirt or let you drift on the track. Hence, the SLIP light is still active.

Maybe, it's just means that wheel slippage has been detected and the VDC is trying to correct the issue. Norammly that just involves reducing power, applying the brakes usually only happens once the vehicle starts to veer off its intended course.
