vdc/asc - - is it fiction

OK been driving hard round recent snow and ice in the 2.4 and have never at any point experienced any of the traction control systems activating. Now I'm not hoping that the system has to trip on because I am driving on the edge but but what should I expect?

Anyone seen theirs ever indicate that it has activated? At one point I wondered whether the remap (F1 and DPF removal) actually included disabling it but I'm sure it wouldn't.

Anyone any experience of this? I thought the traction control might limit the engine power when a wheel spins on ice even at slow speed but not a thing happens.

I experienced it a lot recently, due to heavy snow in DK. You can really feel the traction control was working on overtime. The engine and front wheels were struggling to gain the grip while the yellow light on dashboard was flashing like hell. Glad to have those stuffs, wish I could try the Q4 in that weather condition, should be fun.

Floor the throttle on the ice in 1st gear, then you'll feel it kick in. It brakes the spinning wheel first to try and give traction to the wheel with more grip.

You might think it's poor, but it's a lot better than the RX-8 traction control - that just shuts off all the power to the point where if you gain some grip it might even stall the engine!

I have had the light pop up a few times when I have left the system activated on the Q4 and one wheel started to aquaplane. However its the control over the Q4 where you might not see the lights come up. Given that we have white water coming down again, find a large empty snow covered car park. Try some gentle and not-so-gentle manoeuvres with the ASR/VDC on and then off. You will feel the effect but experience no ASR/VDC warning lights come up until you get quite extreme.
At least that is what i experience with my fully working system

On my 1.9Jtdm the difference between everything turned on (default) and manually switching it all off when driving hard is very noticable.

give it a go, I'm sure you'll be able to tell the difference.

I find that the vdc/asc does not usually kick in when driving on ice and snow as i am being gently with the throttle, as you should be. Only kicks in when i am being lazy flooring it out of corners or from the lights.

i think it's quite an unobtrusive system. certainly compared to the heavy-handed nanny-state set up in my old focus, the dash was forever lit up like a christmas tree in that unless the roads were bone dry

If the ASR/VDC light isn't flashing you're not trying hard enough!


Cars are for crashing, thrashing and fixing

Good luck

thanks for all the comments, today looks like a good day to trial. We have 4 inches of frozen slush in Derby.

I disabled the system on a track session last week.
It took only a few minutes for me to activate it again while realizing I am not the great driver I thought I was...
I now think the TCS on the 159 is a very good system, it allows you to drive around the limits of the car and a bit beyond (making you feel like Michalel Schumacher), but steps in right in time to save you from the tire walls.

If you have any doubts about the electronics of modern brakes look at this:
Volvo Trucks - Emergency braking at its best! - YouTube

It had my heart racing, never mind the person driving the white volvo
