DOD Vibration

**G8Smitty** · 08-15-2008, 10:27 AM

I understand how it would be positive for those who must drive long distances, but for me it sucks. I typically motor around town dropping kids off and going to work, so I'm rarely on the highway. My typical MPG average (last 1000) is 14 to 16, so DoD isn't active for me often, but enough for me not to like it. I'm a prime candidate for the GXP.

Smitty use manual modes in the city when possible. 1 its more fun to drive and it stops a lot of the irritation.

Appears to be worse on lower speeds. RPM is allways below 2K.
Kind of sounds like a manual running too low an RMPM for gear.

I feel a slight vibration. Just ignore it though. How, if I may ask, did you place your DIC in that mode? Is that the process of holding in the left thumbwheel and starting the car?

Yup. Engineering mode.

From my understanding, AFM should not come on when in manual. Once you get HPT, you can see that the settings for AFM are not active when in manual mode. I never tried to see what engineering mode said when in manual.

I've never noticed my car going into DOD mode...I've been trying to watch for it but can never tell.

Hold down the left roller switch on the left side of the steering wheel then turn the key on. You can use the same roller to switch between the various settings. When you see Active Fuel management, stop.

Great, one more thing to play with while I'm driving.

Mine does go into DOD in M4.
