As above really?

I normally leave it on and 99 out of 100 times i never no its there but last night on my way to work which is long and short straights and tight turns and tighter roundabouts i was having a spirited drive as you do and decided id turn the ASR off and the car felt completely different. The backend was sliding around everywhere. I expected understeer on the front but didnt really experience it but the entire car was skitish. I turned it back on for the last few roundabouts and everything was back to normal just the ASR light flashing away instead of the back sliding out

Quite simply it cuts the throttle

 

It does this when it detects slip through through rapid increase in speed via the front ABS sensor ring

This is what i thought so why does my car turn into a slide around with it off lol

The only thing I've ever noticed is a crappy lift-off. I always turn it off because acceleration seems really poor when it's on.

Possibly get more "lift-off" back end movement with the throttle doing what you actually telling it to do, with ASR off?

Casual driving keep it on. "On it" turn it off. Get great lift off oversteer and it allows you to push more round corners.

I think im right in saying when it detects wheelspin or instability it cuts off the power.

VW's own Technical Glossary: ASR and its counterpart MSR
 
It is my understanding that only the ASR system can be turned off by the button marked either ASR or ESP

Another reason for switching it off is that, if the back end steps out, on purpose or otherwise, and you need throttle to drag you out of the slide and back in line, if the ASR is left on, it'll cut power and prevent you from doing this, leading to a spin. Guess how I know, apart from common sense.

Makes you think the maf is shot.

I had it hinder me like this once when I hit a patch of diesel when going around a roundabout. Back end went so I pointed it where I wanted it and applied throttle, it started to pull out of the slide but then the ASR cut in and it had another go at throwing me off the road.

Whenever I'm pushing on a bit I turn it off. I also turn it off when pulling out of busy junctions where yu don't have time to dawdle. Last thing I want when I give it the beans for a quick getaway is a computer says no situation.

Nothing worse than bogging down after pulling out into a tight gap.

Its not even subtle either, it dont take a horse or 2

It takes them all and leaves u with a mule

On a few occasions ive gone full throttle out my estate on to the busy main road and the asr has been that violent i think ive stalled

Its not a great system but at least it can be switched off. Most newer cars you cant completely disable it. VW and mercedes spring to mind.

ASR actually uses two methods of traction control, depending upon your speed.

 

Under 25mph it uses the EDL (electronic differential lock) function. So it pulses the brake caliper of the slipping wheel, which diverts power to the wheel with more grip. It feels pretty harsh when it happens and you can hear the high frequency banging.

 

Above 25mph it does what you guys have mentioned. When it detects slip at a wheel it backs off the throttle via the electronic throttle body, until traction is regained.

 

I'd agree with turning it off for aggressive driving because nobody wants unexpected throttle changes mid-corner when you're on the limit!

 

I do find it actually helps in the snow at low speeds though.

 

It's also great at detecting tiny amounts of aqua planing on the motorway at high speeds and giving you an early warning (in the form of a flashing light)!

My old octavia had the EDL aswell but not ASR. You can actually feel it working on snow and it does help. Although ive had my vrs over 18months not driven on snow in it, all the roads have been cleared by the time ive used it while its been snowing

First thing I do when I get in the car and start it.... turn asr off!

I don't need it, and as above in some situations it can actually be a hindrance more than help.

 

My traction control is in my right foot

First thing I do after turning the car on is press ASR don't even think about it anymore

I always leave mine on unless doing a full throttle starts

In normal driving you dont even know its there

All come with EDL, ASR & MSR

EDL is part of the ABS system though, ASR & MSR are run by the engine control unit

EDL system on the 4x4 is more advanced, can increase/decrease central diff lockup ratio, & works to 50mph

If your car is behaving really badly with it turned off I suspect you've got some issue there

What it might not sure

Had wondered about a dragging rear caliper, but i've experrinced that in a 2wd and it wasn't effected by ASR in the way you've described

dragging front caliper ?

but whatever tbe issue is, ASR should have that type of effect

My old octavia was a 2000 model and no ASR.

Both rear calipers are spanking new and the fronts are fine.

Might just of been a cAse of me been to happy on the throttle but the roundabouts are pretty tight, speeds are no more than 25/30 on them really.

I occasionally get a "crunch" noise coming from one of the front wheels (usually left) when pulling away from a stand still.  I think this is when the ASR cuts in as it usually only happens in the snow or when trying to make a quick getaway in the wet.

 

Does anyone elses VRS do this?

forget about the old cable throttle agu's
