On my VRS Octy, what exactly does ASR do? I know it stands for Anti-slip regulator, is this a posh phrase for traction control?

Also, What is ESP? Which octys have this?

Finally, does anyone know if cruise control can be retro-fitted? How much? Can a main dealer do it?

Cheers Guys.

ASR = Automatic (?) Stability Regime.

It's a combination of ABS (to stop the wheels locking up under heavy braking) and EDL .

EDL, or Electronic Differential Lock, is a bit of a misnomer. What it actually does is compare the speed of the two driven wheels. If one is spinning significantly faster than the other (a sign that it's lost grip) the EDL brakes it momentarily, allowing all the torque to be transferred to the gripping wheel. In order to minimise the shock load on the brake and transmission components, it only operates at low speeds.

ESP is only available on 4X4s - IIRC it's ASR with traction control (throttling back the engine if necessary), but I'm not sure.

Retro-fitting cruise control isn't an official Skoda option (although there were some rumours that it would be available this autumn), but it can be done. There are several threads on the subject if you want to search for them.

other way round..

ASR is anti-slip regulator - its traction control, backs off the power if you are too heavy \ wheelspin.

ESP (4x4's and WRC's) - electronic stability programme - brakes individual wheels to counter oversteer \ understeer, can also reign in power as last resort.

oh and real men turn it off... wimpy blokes leave it on ... and total big girls blouses buy a car with ESP

and those who prefer mineral water and DKNY have esp and 4x4:p

Ignore ffelan, it's getting close to feeding time and he gets agitated.

just eaten actually, was nice FRUIT GUMS! my favourite...

(apart from 4x4's for breakfast;) )

- i was only fishing for Denis.... but guess he is not biting...must be out of season?

ASR is indeed Anti-Slip Regulator - but to call it traction control is over selling it a bit -- it is fairly limited it what it can do -- it only works at speed's of less than 25 mph,and if you really gun it - the car realises it won't cope and gives up.

E.S.P uses measurements taken from all 4 ABS speed sensors,a steering angle sensor and a longitude and latitude sensor -- taking all those readings as well as wether brakes or throttle are being applied it decides wether to drop engine power,brake individual wheels or all wheels.

E.S.P Plus is currently under development by BOSCH -- it goes a stage further by using electric PAS -- which it can over-ride! in extreme cases to assist in rectify skids.

OK hands up I qualify for the "wimpy blokes" in leaving the ASR on , on Sunday . But at Pembrey on the circuit , the right hander down the back straight - which I agree with Paul , was taken flat - going through there I noticed the ASR light flickering on and off , so what was happening there ?

Light still works - as a warning that you may be trying too hard for a "Wimpy bloke" - but it isn't really ment to cope with that sort of running.

And Whats Wrong With Mineral Water?

If I had known that , I would have switched it off and been a real man

That's easy that......you just change your underpants.

....and i thought i was taking the thread in vain.. i do stand by my post though.. asr is pointless and when people understand how little it does it is a bit wimpy to leave it on... esp is more useful for inexperienced drivers / those not "interested" in driving but for the commited its still a hinderence except in extreme conditions

so switch it off. I'll take all the driver aids you can give me for that late, dark, icy, raining drive when the truck pulls out on me - but I'll switch it off for enthusiastic driving.

(that said, ESP can brake an individual wheel which *no* driver no matter what skill level can do, so it is possible to get round tight corners very quickly with it.)

As long as it's switchable, gimme all you got.

That's only because you're not given control over brakes independently.

Rob.

Exactly - until someone does an octavia with four brake pedals I'll stick to ESP

(I've seen autotest cars with two handbrakes tho, one for each rear wheel, they can flick round tight corners incredibly well)
