just double checking with fellow members. When I push the DTC button, the DTC lights up on the dash but "!" also lights up? When the DTC button is pressed again to OFF, the "!" also goes away. Is this normal?

yes, that's my recollection

[///Matt]

yeah, it's normal. the " /!\ " is telling you there is a warning on in your "Check control" screen.

why is the /!\ on and stay on when the DTC button is Pressed ON though ?

anytime both DTC and DSC aren't on, the car will give you that warning.

[theroyalwe]

does it still do it when your seatbelt is buckled?

Actually it's when DTC is on and DSC is off, it will give you that warning.

one press and DTC is partially off...if you press it agian, DTC will be back on. If you want it fully off, you have to press and HOLD for 3-4 seconds....

actually no. it happens like i said anytime either is off. so you'll get the /!\ if you press the DTC button briefly which turns off DSC and leaves on DTC, and also if you press and hold the DTC button for several seconds thus disabling both DTC and DSC.

unfortunatly you said both not either, so it could be interpreted either way

Your post is a bit contradicting there but I get what you are trying to say.

For your information, DTC is on, DSC is 'restricted' when you press the DTC button momentarily and everything is off when you press and hold.

my average miles per gallon for the las 1k miles is 15, i was going to take a picture and see if anyone could beat it, but i realized you could just reset it and roll for 50 feet in first gear and get lower than 15

...because you're not turning anything ON, you're turning part or all of the traction control OFF. That's why the icon is displayed, because you're turning OFF either part or all of your traction control depending on how long you hold down the button. I don't understand why people get this confused...

Here's some more info to muddy the waters even more.
On page 59 of the first quarter of 2007 BMW Magazine it states."Also, a quick jab on the Dynamic Stability (DSC) button before starting the climb activates Dynamic Traction Control (DTC)."
So much confusion over a single button.
To me this means (DSC) is on all the time and a single quick push activates (DTC)
and if you hold the button down it turns both off. Call me stupid but I don't know.

Its 2 seperate sets of software

the one allowing more wheelspin ect than the other at low speed ( at higher speed the laws are the same as DSC )


The DSC software is functional when you start the car

If you press the DTC it activates the DTC software

When you hold the button in it deactivates both

This is what I'm talking about. According to the BMW magazine it's turning (DTC) on, not turning anything off. If you hold the button it turns everything off. As far as I'm concerned people are guessing. I'll have to wait to try it to find out for myself. Everyone thinks they are experts. BMW doesn't even know how to explain it so people can understand it.
