Right guys

Rather than just fit limited slip differentials like renault and ford do, VAG have developed the XDS equivalent which essentially is an electronic aid that brakes the spinning wheel giving traction and applies brajkes as required to help the turn in.

Previously ive never been an advocate of it as my inside wheel would easily spin on tight hairpins on track

A bitof research from Hurdy and it turns out that VAG have 3 settings that the XDS can be set on.

Setting Zero - Soft The Fabia vRS is set here as standard.

Setting One - Medium

Setting 2 - Strong

Mine has now been set to setting 2 by Jabbasport via the VCDS cable and laptop and ***& me its better.

Massive improvement in turn in, the inside tyre doesnt spin up no where near as much as before ( and onsider the really cold weather as well) and you can feel it tug the car into a tighter line on corners now.

Massive improvment and at No cost

You can also change your brake assist for stronger initial response to the pedal

Changed a couple of the settings in VCDS today, took the car for a spin and the difference is superb.

Changes made.....

In VCDS Select Control Module, go to 03 ABS Brakes, then 10 Adaptation, go to Channel:

Channel 09 Brake Assist

There are 3 settings for this

0-center (stock setting)

1-small

2-hard

I changed this from the stock 0 setting to 2 and this has made the brake pedal more responsive to smaller inputs. Feels more positive in use, especially under enthusiastic motoring.

Channel 36 XDS

There are 3 settings

0-center (stock setting)

1-weak

2-strong

Again I changed this from 0 to 2 and this one mod alone makes the Polo into a different/better beast under hard driving. It acts almost like my ED30 did with the Quaife and yet doesn't feel as fidgety. Seems more planted around bends and that much better to push through the corner on exit. This mod comes with a five thumbs up...

Someone near me fancy activating for beer tokens

Definetly needs the brakes on the higher setting i think, will get it changed up at my dads work when its in gettin the anoyying double press lock thing fixed : )

Im doing the brake settings tomorrow

Hmmmm .......

Word of warning. I researched a bit more on the yank forums about this. Some were scaremongering about CV joints snapping.

Essentially the drive shafts are still being driven whilst the brakes try and slowe them down to stop spinning. So theres quite a lot of shear being applied to the driveshaft/CV joint.

SO IF YOU CHANGE IT and something goes tits, there is a warning here. Im happy to do it still lol

Brilliant Simon, will have to visit Simbo for a play, not tommorow with all the snow forecast and yorkshire meet on Sunday

Is that with the harder XDS setting, the higher brake setting or both mate?

Al

Not sure if the pre-face lift had the XDS at all. the facelift does.

Carl checked his and it was already on setting two

nice one sy will have a play at weston where Jason can plug in for me

edit: might go for "meduim"

Great find!

Exactly - only so much you can do without a proper LSD!

I wonder how they could tell who done it though. Just act ignorant and say its how it come. Plus i don't see how they could argue the warranty claim as its a setting that VW have put on the car.

Exactly. If it broke I would just turn ot back to zero.

VRSPowered

The warning was reference the XDS settings

With the amount of mistakes they make doing final checks and the wide variety of settings people get their cars with I'm sure some people have had it on 2 from new

From what I can see with the XDS mod this is just applying more brake to stop the inside wheel from spinning,this will put more heat into the front brakes which struggle to cope on track.

But is this any different to normal operation? After all the torque is transferred through the diff to the other wheel (which of course if the point). Whereas accelerating full-throttle (with traction) and at top speed, all the torque is being loaded on the CV joints with nowhere else for it to go.

Also isn't this exactly how Audi's Quatro system has worked for very many years?

No idea. I was just pointing out the scaremongering so people could make a decision whether or not they wanted the risk

This is true. You have better fluid already, just throw on a set of decent pads and you'll be fine.

From what I remember Paul saying about his track work he thought the XDS was a root cause of his brakes over heating after some hot laps as he wasn't actually using the brakes that hard.

Still cool though. Had a feeling something like this would be possible. Just like changing steering weights.

Any more news on this? By that I mean who has had it done now and has it been an improvement, any problems etc

not at weston yet , end of march, but I will see if someone can alter the settings on mine, just to medium mind, not hard.... just to see

Just had mine done at the NW meet, feels a lot more twitchy and responsive.

Corners a lot better.

That's on a 5 minute test, needs properly testing.

which setting did you put it on?
