I've read the manual, but am still not positive what the difference is between traction control, active handling, and comp mode. Can someone please explain the difference to me?

Also, I heard that in an A6 while in comp mode the paddle shifters are more responsive. Is this true? Can someone elaborate?

Thanks everyone!

 

Also, is their any one that is particularly better to use under certain driving conditions then another? Is one better in rain then the other? Is one specific for track use? Etc....

 

The 1st two are for safety and security.Accident avoidance,etc.That last one is for your driving pleasure.It limits the nanny's watching you while you play with your car.It allows more driver input,as it were.You can turn off all 3 to get the exact idea of what I'm referring to. Just hold on if you do!!

 

What do you mean it "limits the nanny's watching you"? What's a nanny?

 

I should have mentioned that I'm a bit of a newb, so if you could dumb it down a bit for me that would be appreciatted. Thanks!

 

Hit the button once...you have control of the rear wheels, and the computer will do everything it can to keep you between the ditches. Good for drag racing.
Twice....you have control of the rear wheels, and the computer will not do as much to correct you. Something you can use while road racing, or running the autocross.
Three bumps(or hold it down for a few seconds).....and the car is all yours. No help from the nannies, and I see no real need in this, unless your father happens to own a body shop.
Driving in rain I would leave all the nannies on. Don't hit the button.
Don't know about the paddle shifter....mine only comes in a stick.
Nannies....another word for your 'watchful mother' the computer.

Everytime you start the car it starts with Traction Control (TC) and Active Handling (AH) both ON.

If you press and hold the TC button for 10 seconds you turn both AH and TC functions off. No electronic controls.

If you press and release the button once you turn off TC but leave AH on.

If you press and release the button a second time you are in Competition Mode which turns TC OFF and reduces the AH interference.

 

Traction control works to limit rear wheel slip. It does this by controlling engine torque and rear brake application. If the Electronic Brake Control Module detects excessive rear wheel slip it will send a message to the Engine Control Module telling it to reduce torque. If the torque reduction is insufficient the EBCM will also apply one or both rear brakes. The system is set up to allow both rear wheels to spin a fair amount but if just one spins it intervenes quite quickly.

Active handling is a function of the EBCM which assists the driver in maintaining directional control of the car. It uses the lateral G sensor, the yaw sensor and the steering sensor to detect if the car is responding properly to the driver's input through the steering wheel. So if you initiate a turn with the steering wheel and the car doesn't respond as quickly as the steering input indicated it should (understeer) the EBCM will apply a single brake to yaw the car further in the direction you turned the steering wheel. If it responds quicker than indicated by the steering input (oversteer) it will apply a single brake to reduce the yaw rate so the backend doesn't come around on you. For understeer it usually applies the inside rear brake and for oversteer it usually applies the outside front brake. Inside and outside refer to the position of the car in a corner. The side toward the turn is the inside and the side away from the turn is the outside. Comp mode is a special feature of active handling which opens the dead band (the spot where the system will not react) and allows the driver to throw the car around some more.

Always leave everything on for street use. You can turn everything off at the autocross to see what happens and learn to handle the car. AH on and TC off for dragstrip. I'll let others address HPDE.
