XDS Strength and Torque Steer Compensation tweaks: GTI

[AdamD]

Whilst perusing a list of popular MkVI VCDS tweaks on golfmk6.com, I came across a couple of more recent discoveries that haven't been discussed over here before (that I recall):

Electronic Differential Lock (XDS) Strength
XDS is the electronic differential lock. On higher HP models (Scirocco R), this is set to 2, whereas the default on the GTI is 0. At 2, the system is more aggressive at applying brake pressure to the inside/slipping tyre.

Torque Steer Compensation (TSC)
Using the Steering Assist controller (not the brakes), TSC will help prevent torque steer on tuned cars. A TSC of 1 is used by default in higher HP FWD VW models like the VR6 FWD Passat.
VAG-COM — Torque Steer Compensation (update: it works!)

The latter tweak in particular sounds very interesting. To quote from that last thread:

Was out on Hwy 1 North of Jenner this weekend. Wife and I stayed at Sea Ranch for a long 4 day weekend,.....enabled XDS and this TCS and spent hours ripping up and down the coast.

Amazing, the car felt like it was on rails!! Coming out of tight turns and hard acceleration and the car just took off straight.

Had a permanent smile on my face, just amazing.

Transforms the car! I will never go back.

I haven't verified that these settings apply and/or take on Australian-spec GTIs, but if they do... sounds promising!

A few people have with Mk6 GTI's have done the XDL change from vwgolf.net and reported that the car feels different when cornering. But i havent seen or heard of point 2 that you have raised.

Would the TSC tweak work for tuned 118 TSI's? Obviously we don't have XDL.

I know this is a golf forum but I have done the XDL tweak on my Polo GTI and it is very noticeable compared to stock. The torque steer control is an odd one though because in my polo I very rarely get torque steer, what I do get though is the feeling of a locked front diff and when accelerating hard from a standstill, wherever the wheel is pointing, it feels tight when trying to move it from its position. I wonder if this is pre-programmed onthe polo...

[Ryan_R]

I've had TS once or twice when TC was turned off

Very curious about being able to "dial up" the XDL... Be nice to tame that inside wheel spinning, a little further.

Give it a go Ryan! By all accounts the difference can be quite marked. You'll want to do before and after comparisons, heavy acceleration in first gear with your hands off the wheel. In a safe environment of course.

Gotta wait for my new clutch pack to be installed and have APR reloaded first

I had problems with ineffective XDL on my MY11 vRS Octavia, so wound it up with VCDS to setting 2, and it made bugger all difference. It still spins quite a few revolutions of the inside front wheel before there's any semblance of braking, but even then, it still allows a significant amount of wheelspin.

So is there a problem with the XDS/XDL on your car, or do you just feel it doesn't have much effect? AFAIK it's not designed to rein in big wheelspin (the T/C is for that, and the last thing you'd want to be doing is putting all that load on the brakes), but rather marginally diverting torque to the outside wheel by increasing the resistance to the unloaded wheel while accelerating with a fair amount of lock on.

Anyone try the TSC yet? It's been lousy weather in Adelaide and I've not yet had time to code my car and go for a hills run.

Apparently ESP can be disabled by disabling the source of information the system relies on (this will result in dash light errors though)

Set Brake Assist to 2 and set Hill Assist to 'early', other XDS stuff not available on my car.

Brakes let go a little earlier now on hills which should hopefully help with DSG jerkiness in those situations. Car starts to roll back a cm but it's easy to catch on the accelerator just like a normal manual.

VCDS description was also interesting in how the car "adjusts torque levels" for hill start assist, which could have something to do with jerky uphill starts on tuned cars with more torque.

Notice any difference with the Brake Assist change? What did you have it set to previously?

[Ryan_R]

Comes on a little bit earlier, still very easy to use. Was on 0 - Normal before. Will keep both settings changed at least for now.

[+] Ended up reverting brake assist to normal setting, as the quick application caused jerky behaviour in slow start/stop driving (i.e. takeaway food drive-thru).
