When should I turn on my DTC BMW?
You use the default (no lights / no button push / full traction control) when you’re driving, especially if it’s slippery. The computer is on and trying to keep you going where you want. You use DTC (one button push) when you want to allow some wheel spin without having the traction control system pull the power off.
What is the DTC button on BMW?
Dynamic Traction Control (DTC) allows for sports-style driving dynamics even when DSC is controlling stability and when wheel traction is higher. Dynamic Traction Control (DTC) is a sub-function of the Dynamic Stability Control (DSC) system that can be turned on and off.
Is DTC good for rain?
DTC only is better for sand, snow, slush as it allows some wheel spin to get you moving. Leaving the button alone in standard contitions is the safest way to drive.

Dynamic Traction Control
Dynamic Traction Control (DTC) allows for sports-style driving dynamics even when DSC is controlling stability and when wheel traction is higher. The Dynamic Stability Control system curbs the engine output and stops slip on the wheels.
How do you read a DTC code?
To read the codes, you will have to plug a scan tool or code reader into the 16-pin OBD II diagnostic connector, which is usually located under the dash near the steering column. The tool will then display the code or codes that have turned on the Check Engine Light. To read codes, you need the proper scan tool.

What’s the difference between DSC and DTC in a BMW?
Dynamic Traction Control (DTC) allows more wheel slip and thus a more dynamic driving style with higher wheel traction and DSC controlling stability. A small amount of spin on the drive wheels improves traction when pulling off from a standstill in snow or on loose terrain.
Why do you need DSC on a 320i?
Even in a 320i (E90). The need for DSC is because you don’t have control of other cars and obstacles on the road. If you need to do an emergency lane change and you have the DSC off, it’s going to be difficult. When you drive around a track, it’s best to keep the DSC off and just drive smooth.
What happens when you press the DTC button?
When you press DTC button once and you get DTC light on means you have turned OFF the dynamic traction control but it will keep DSC running. Now you’re allowing wheel spin only if you’re driving forward but in case of any side slipping the car will not allow the spin to happen and that, of course, to prevent drifting.
