Don't hit the track without these 5 OBD11 tweaks (mk7 GTI)

[@boostedbliss07MK5]

Do you have a video actually showing how to do any of these tweaks? Left out the meat and potatoes....

[@driftozphotography]

i know this is an old vid but your wrong about the XDS it has nothing to do with rear wheels. The XDS electronic differential lock improves the traction and handling of front-wheel-drive models. In technical terms, the XDS system, initially developed for the Golf GTI, is an extension of the electronic differential lock (EDS) integrated in the ESP system. As soon as the electronics detect excessive unloading of the inside wheel of the driven front axle during fast cornering, the ESP hydraulic system builds up braking system pressure in a targeted way on this wheel to restore optimum traction. This way, the XDS acts as a limited-slip differential to compensate for the understeer typical of front-wheel-drive cars during fast cornering.

[@takikolokithi7943]

True ! Xds applies only to frond wheels

[@kwa_nguyen]

awesome video mate. Keep it up.

[@trackhackau]

Thank you! Appreciate the feedback!

[@michaelw6277]

XDS applies the brake to a spinning inside wheel to aid in allowing torque to go to the drive wheel with traction. The effect is the same as if you have a limited slip differential, although it is weaker than a good limited slip as brakes are easily overcome by the engine and hamfisted throttle input will overpower it. It works extremely well on my Mk6 GTI and it definitely has a hugely positive effect on corner exit.

[@trackhackau]

I've tried it both ways, low and normal. Verdict is still out. VAQ works pretty well though.

[@michaelw6277]

@@trackhackau I'm sure VAQ is next level great, especially when combined with XDS. But as my car has XDS alone I can only really comment on that. About a year ago my ABS control module failed, leading to XDS not functioning. Prior to that I always thought XDS probably wasn't doing all that much, but having driven without it on a purely open differential showed that it does an awful lot more than I originally thought. I'm not sure if you can easily disable both VAQ and XDS via scan tool, but if you can it might be worth trying just to see how each contributes. One of these days I'll install a proper mechanical limited slip differential, but at near stock power levels the GTI really doesn't need it as XDS is surprisingly effective.

Nice video, good tips!

[@trackhackau]

Thanks mate. Appreciate the feedback.

[@onlydavid]

About the “Increased Traction” setting on Golf Rs, I feel like this actually slows the car down by reducing power when a wheel starts to slip. I’m just not so sure about it.

[@trackhackau]

Hey mate, I don't have an R so can't comment from experience. But I do know that the haldex doesn't reduce power. It transfers power. What reduces power is the "Starting vibration" option. This by default kills power in 1st and 2nd gear. This mod (it is believed) just increases the pressure so the haled responds faster and with more pressure. If you are getting excessive wheelsman in an R perhaps you need to get your Haldex looked at. It's not uncommon to have pump failures. Or it might just need a service.

[@ZZGTKING]

Thanks, I was always complaining that the brake pedal is not that linear

[@trackhackau]

You’re welcome!

[@ZZGTKING]

Track Hack BTW what’s the VCDS access code for straight ahead brake stabilization? I tried all kinds on the internet but get no luck :(

[@trackhackau]

Should be one of these 11966 37202 31857 28183 44595 24435 15081 18573

[@ZZGTKING]

Track Hack Tried all of them today, no luck...

[@christianmagana329]

will doing these tweaks in obd11 pop a td1 for the newer models? great video btw, i would love to try these out but i still want to keep my warranty for now

[@trackhackau]

It won't cause a TD1. Only a tune will do that.

[@christianmagana329]

Track Hack awesome👍🏽

[@tss996gt3]

Thanks so much for the info! I was wondering though how safe it would be for casual street driving to disable brake stabilization, I hope ABS and EBFD would still activate. I'm also wondering how much of a hit to casual driving comfort vs control would change if I disabled the torque limiter and brake/throttle smoothing. I really don't plan on tracking my car, but I still would think disabling ESC, setting XDS to weak and setting the diff to increased traction would improve driver engagement enough while still maintaining comfort and safety, what are your thoughts on this?

[@trackhackau]

All the changes are totally fine for street driving. You won't even notice them. Doesn't impact ABS at all. Stability control is also not impacted when it's enabled. Torque limiter you will only notice from a dig. You will either fry tyres more, or wheel hop more if on factory mounts. After doing this video I've read up more and I think leaving XDS to normal may be best. I've changed mine back but I'm waiting on my next track event to test more. Theory is that it acts as a pre-load to the VAQ. But either is still fine. You won't notice it on the street unless in the canyons etc. None of these changes will compromise safety in any way. Always drive within your limits though, especially on the street.

[@Hatchbacksnerd]

I wish you did another video with all those mods by the vcds

[@trackhackau]

Which ones do you want me to cover? Happy to do more on this topic.

[@Hatchbacksnerd]

@@trackhackau hello and thank you for replying. I would love to see all five step in a new video how to do it with the vcds. Like the xds and esp and the diff increasing. There is no video on youtube Where u can find some one who explaining the whole process so of you can maybe do it one time for all. Thanks

[@sowjoji]

Could you explain XDS a bit more? Planning on doing a bit of autocross with the car and wondering if I should leave the XDS alone to help with car rotation or turn it to weak to help with straight out speed.

[@trackhackau]

Hi Gary, lots of people have experimented with XDS and autocross. The consensus is that having it on strong feels like you are rotating more. It’s actually slowing the car down while doing so. I wouldn’t put it to weak unless you have the Performance Pack with the VAQ differential. As reducing XDS is allowing more work through to the VAQ. To get more rotation I actually play with my tire pressures so I can induce lift off oversteer easier. Rear sway bar is the proper fix for this. I would actually just try all settings on different runs. The theory is never as good as just giving it a go.

[@LoveLikeaHurricane]

Difference between ASR off and ESC sport? I have Mk5 gti and ASR on that car is referred to reduce engine power when the car defects loss of traction.

[@trackhackau]

ASR - Anti Slip regulation ESC - Electronic Stability Control ASR is basically traction control and yes it cuts power when it detects when slip under acceleration. ESC is your stability control. ESC Sport will allow a little bit of play before intervening, eg it will allow a touch of lift off oversteer. Then it will use the brakes on each wheel to straighten you up. Great safety feature, no good on the track though. Perhaps I'll do a video to explain the difference in more detail and the various long coding options available.

[@M-28xD]

Would be nice if you showed up were those options are!

[@trackhackau]

I will do some more detailed videos

[@M-28xD]

@@trackhackau too late now mate. Ended up buying a wave track LSD and a dadason motorshport clutch for my drag setup🤣🤣🤣🤣👍👍👍👍 Still nice if you make the video though. Thanks mate.

[@peterbennpan7288]

So you will have the setting in the infortainment system for diff on and off. If you code the diff to increased traction will this setting always be switched to on then even if the setting in the infotainment system is switched to normal?

[@trackhackau]

Settings in infotainment don't change. Looks the same. I'm not positive what the change does too all settings. IE does it change normal to sport and sport becomes increased traction. My guess is that it only impacts the Sport diff setting.

[@RobH0600Events]

Hey Andrew, how important is it to do the reset procedure for the VAQ?

[@trackhackau]

I wouldn't say it's "important" but in my view it certainly can't hurt if you are beating on it frequently. Admittedly I haven't reset mine in a while and it probably over-due.

[@HaveOneWithHans]

Hey bud does the torque limiter apply to the R or just gti

[@trackhackau]

Should be both. Check and see if the adaptation is there.

[@sparkplug964]

Am I right in thinking that OBD11 can turn the traction control off on a GTI with Performance Pack?

[@trackhackau]

Yes it can. You need to change the way the button works so that long press is off.

[@sparkplug964]

​@@trackhackau I managed to set this up with ODB11 which is great, 1 pass sports mode, long press TC off. But this does not actually turn off the TC, you have to also deactivate the Starting Vibration Reduction in control modules, without deactivating Starting Vibration Reduction, TC will not be fully off. Hope this helps.

[@TheAsheryl]

Same as mk5 gti and mk6 gti?

[@trackhackau]

I don't believe so. They are MQB only.

[@h4xor1701]

Hi! Can you teel me more about the "Starting vibration Deactivation" option? Is this mod effective only when you put the car in ESC Off, or you can not more use the ASR for 'normal' driving?

[@trackhackau]

It’s separate and independent from ASR and ESC sport/on/off. This option stops the car from reducing torque in low gears when you lose traction. It’s to stop you from axel tramping.

[@h4xor1701]

@@trackhackau I've tried to disable the 'starting vibration reduction' but in my '19 Golf GTI PP I can't find anywhere that adaptation. Do you know if it can be coded via long coding istead?
