ABS = Anti-lock Braking System

This uses sensors in each wheel hub carrier and a magnetic reluctor ring on the hub to sense the speed of the wheels. If during braking one or more wheels are going slower than the others, indicating that those wheel(s) have slowed their rotational speed (loss of traction/skidding) and could lock, then the brake(s) on those wheel(s) are released until those wheel speeds match the others.

Works on all wheels during braking only, to prevent wheel(s) locking and skidding. This is "ON" all the time and cannot be deactivated or switched off, unless the main fuse is pulled. The warning lamp on the dash will flicker on and off when the system has been activated, and you will feel a "pulsing" (quite sudden and heavy) through the brake pedal, as if it is trying to push back into your foot. If the warning lamp is permenatly illuminated, this indicateds a problem/fault with the ABS system, and that the ABS system is now deactivated to protect itself. In this case braking is "Old School" without ABS!

MSR = Mechanical (or Motor) Slip Regulation

This uses the engine's ECU to reduce the torque supplied to the drive wheels to reduce wheel spin, eg it reduces the power output (via the ignition timing/sparks/fuel, etc) of the engine to prevent further wheel spin, mainly when changing down gears on a smooth or slippery surfce. It has also been reported that whilst under full power (from standstill) coming out of a junction it has suddenly cut power to reduce wheel slippage, thus leaving you halfway across the junction now under reduced power! This function can not be deactivated or switched off, nor does it flicker any lights on the dash when it has been activated!

EDL = Electronic Differential Lock

This requires the car to have ABS to operate.

This will use the ABS sensors on the main drive axle (front) to sense if one of the drive wheels is rotating faster than the other. It will then brake that drive wheel until both the drive wheels are at the same speed. This works then the accelerator is being used and the brakes are not. Effectively this works as an LSD and is also known as "Fiddle Brakes" and has been used in F1, with manual versions used in tractors, hill climb racing, and 4x4 trail racing. This is always "ON" and cannot be deactivated unless the main fuse for the ABS unit is pulled. When this is working "Active" there is no light that flashes/flickers etc to tell you it is working!

ASR = Anti Slip Regulation

This requires the car to have EDL, MSR, & ABS to operate.

This will use the ABS sensors to sense if the driven wheels (front on FWD) are rotating faster than the non-driven rear wheels . It will then brake the drive wheels until both the drive wheels are at the same speed as the rear non driven wheels. It can also use the MSR function to help reduce the power to the drive wheels if needed. This works then the accelerator is being used and the brakes are not. There will be a switch on the dash to deactivate this. The system is "ON" all the time. Pressing the switch deactivates the function and illuminates the respective warning lamp on the dash. If the ignition is then switched "OFF" and then back "ON", the ASR resets to default "ON" again! When this is working "Active" the warning lamp on the dash flashes on and off, indicating that it is currently sorting out the lack of traction!!

ESP = Electronic Stability Program (In this case NOT Extra Sensory Perception.. )

This requires the car to have ASR (EDL, MSR & ABS) to operate.

This system uses a gyro sensor fitted behind the lower central dash (usually on the exhaust tunnel) to sense cornering, g-force, etc, etc,. It will also use information from the ABS system, power steering wheel sensor, engine ECU, etc to work out what the car is doing and the current inputs by the driver. It then compares these actual readings against predetermined values and then according to the situation it will either brake individual wheel(s), and/or reduce engine output. All to reduce the amount of under or over steer and keep the car on the course steered by the driver! The system is "ON" all the time. Pressing the switch deactivates the function and illuminates the respective warning lamp on the dash. If the ignition is then switched "OFF" and then back "ON", the ESP resets to default "ON" again! When this is working "Active" the warning lamp on the dash flashes on and off, indicating that it is currently sorting out the lack of traction and stability!!

Fabia, MKI spec combination list

1. Nothing, not even ABS! Only on early pre face lift Classic models in certain engines.

2. ABS

3. ABS & ASR (ASR includes EDL & MSR)

4. ABS & ESP (ESP includes ASR, EDL & MSR). ESP was a factory fit option on vRS version only!

So how do you tell which of these you have fitted?

I'm guessing ESP would have an ESP button on the dash, ASR has an ASR button, ABS would have nothing but you'd feel the pedal pulsing when you're about to lock up, and with nothing you'd just lock up and understeer horribly into the nearest object...

Also, according to fabdavrav's post you can't turn the EDL off anyway, so although you'd got the ASR off via the switch (which means the car wasn't trying to match the front wheel speed to the rear wheel speed), it still would have been trying to electronically match left front and right front. Very useful post that, when I found it, and fabdav has reproduced it here as well as my link, it's worth a read through IMO

Thanks fabdavrav.

That's cleared some things up.

And yes with an LSD although the EDL will still be present and working it probably won't intervene as much as there won't be as much of a difference in wheel speed (front left and right) due to the LSD.

CORRECT!!!!!!!!

@BossFox...

If you look at the passenger side of the engine bay at the rear and you don't have a 6inch square block that is hafl shiny alu and half black plastic with a black metal cylinder on the side you have nothing...not even ABS......If you so you have ABS at least!!!

If on the row of buttons above the HIFI you have a button marked ASR.....you have ABS, EDL, MSR, ASR

If that button instead says ESP...you have ABS, EDL, ASR, MSR, ESP...

ASR only brakes the front drive wheels.....ESP can brake all four wheels.....as for "stability"

Simples...

Esp is simply awesome!

Last year in the snow with a 267bhp golf gt tdi i couldnt even spin the wheels

I had a mate with ESP, killed the power on a track session mid bend because he had a bit of lift off over steer. I`v no doubt it helps in adverse conditions, but after that moment it got turned off if giving it some beans.

As for ASR, it is very over sensitive, it kicks in way before the wheels are actually spinning. I am capable of pulling away without it kicking in, but its possible to get away much quicker with it off. As someone previously said, it`ll be doing much less work if your running a diff, my mate very rarely has it come on now his is fitted compared to mine.

I have ASR and an LSD and it seems to work very well.

Don't pull away so quickly or if you must control your right foot.. IMO it sounds like your heavy footed and can't drive the car correctly

why do people always do this

i want to remove the ASR. i didnt ask for comments on my driving

sounds like you can't read correctly

Definitely, I was moaning about mine and he said his doesnt cut in much even with his naff tyres. I have a excuse now for a diff, it`ll fix the asr

This is my car with ASR on. What's the problem?

ross' car is awful with ASR too, always turned off, so SE's ain't any different

must be the driving style + tyres

when cornering hard if you slightly lose traction it cuts the power for ages, it's actually really dangerous IMO, i just want it gone completely

Do you know anyone with VCDS?

Worth a try to code it out.

Speak to your mapper to see if it can be turned off....forever

I'm guessing it an ecu feature.

Asr is simply ****

Not quite end of discussion, you haven't answered the orignal posters question.

It seems that you would just have to code to ABS controller to tell it that it doesn't have ASR.

Some info here which may be of some use:

I've got a copy but I'm dubious of applying unknown coding to something as critical as my ABS controller the controller on my car definitely ends in the right 3 digits but I'm thinking they must just be a description of the parts function. The posts you linked to last night refer to the 1C0/1J0 modules which are often found on A platform cars (i.e. Golfs) so even though the last 3 digits match, the other digits are different and my starting coding is 00008 which is way off any of the examples...

Think I'll wait and see what Luke does, see what his starting coding is and what he might end up with to turn stuff off...he's got more money than me to replace the controller if it borks

I'm just having a look through the VCDS label files to see if there's any clues in there.....

edit - It seems that my module is sort of "mismatched". The part number is 6Q0 907 379 AB which according to one label file is ABS/EDS/ASR 5.7 and redirects to the appropriate label file for that particular module.

REDIRECT,6Q0-907-37x-ASR.LBL,6Q0-907-37?-AB ; ABS/EDS/ASR 5.7 *

However, in logs and the VCDS main UI, it reports itself as Component: MABS 8.0 front H03 0001, whereas v8.0 modules in the label files should have a different part number.

I thought all fabs had Asr and abs etc I know mine does

Nope, Techie put a picture up of his interior a while ago with no ASR button (his is a classic I think)

I read it perfectly, What you need to understand is that ASR etc is fitted to cars to try and aid the driver gain control over their car should the car detect it may be going out of control, these aids shouldn't interfere in normal driving conditions and if they are then the car isn't being driven correctly, unless the roads are snowy/icy in which case I can understand needing to press the button to turn it off. I can't remember the last time I had any flashing yellow lights on my dash through accelerating so hard as to break the traction of the tyres, even when I had a fabia (admitidly it wasn't modyfied) but any car can be pushed hard enough to bring on any traction control lights if driven agressivly

You openly admit that it must be the driving style & by driving hard you are loosing traction and therefore loosing control of your car as you are driving beyond the cars limits. Completely removing these driving aids you are risking not being able to recover the vehicle in a slide and potentially killing someone.

I'm glad I don't live near you as IMO you sound dangerous on the roads.

I think its quite funny that some people like BossFox has an LSD and a "modified" (only slightly.... ) car and has NO problems with the ASR........yet the OP openly admits that his "problems" with the ASR might be down to his driving style!.........

So if the OP wants do disable the ASR...let him......and if he decides to stuff himself into the scenery (by his standard of driving and now with no ASR to help out) then so be it (he'll never do that again)....just so long as he does it on a race track and not on the public road where he might kill someone!!!

I think the thing is it's very easy to forget just how much power/torque can be achieved with very little effort and even in a standard car I have found it isn't hard at all to get the little light flashing on the dash (without actually driving out of control) so in a modified car it must be all the more easy to push just that little bit too hard on the go pedal and overwhelm the tyres!
