The VAQ diff is computer controlled and it's integrated into the ABS system through the BCAN, so in stock form on the PP GTI it isn't very performance focused like the exact same unit found in the GTI Clubsport S and Seat Cupra 280 is (both of which broke FWD Nurburgring records with this setup too). : Great article! I just thought that comparing a track built MK7 *insert cheesy smile* with a mechanical diff to a minor bolt-on street focused MK7 PP with the VAQ diff was not quite a fair comparison. Have you made any headway yourself about tuning the PP diff? Do you mind sharing how you did it? : I recently did an article about the PP diff which you pointed out has the potential for a lot of tuning.

So if you're adventurous, this might be a hack for you.īrake stabilization tweak. Nevertheless, I've come a long way since that first track day. In fact, I don't even think it always occurred to me how much rotation was happening. I've personally had people come up to me before telling me they thought I was going to spin, but XDS kept the car in check. Trail braking can get you quite a bit of yaw, yet the XDS system can really save your ass and make you look much better than you are. I can personally attest that learning the MK7 on track was a somewhat wild experience.

The same goes for a less experienced drivers too, with XDS+ and ESC on, it can make even a Novice Driver look like a hero on some less technical tracks as the system works pretty well and keep you in line if you are pushing the car at only 80% or so. But if you are on a road course with a non-track worthy tire, the XDS+ system can help create a little more rotation to "artificially" fight understeer. I disable the system completely when I'm on track tires as I have found that it makes for significantly slower lap times. : I like XDS+ for the streets, I hate it on the track, but that's my personal opinion as a track enthusiast. For a track (circuit) car, do you think the car would perform better with or without it? Besides adjusting the ESC button, do you know of any other XDS tweaks? : Diff or no diff, the XDS/XDS+ system also seems to be a hot topic.

Fortunately, we can adjust the intensity level of XDS (how much brake pressure is applied to the inside wheels) as well as disable it completely. On track it can be an unmanageable system you are fighting. On street it can be a life safer, by adjusting the car's yaw, as well as helping it to corner harder. As you can imagine, XDS helps rotation, but at a cost of less driver control, and more brake use. The main difference between XDS and XDS+ is the actuation of the front wheel only for the former, vs the front and rear for the latter. The precise, one-sided build-up of brake pressure makes cornering even sportier, quicker and more accurate." - en./en/innovation-and-technology/technical-glossary/elektronische_differenzialsperrexds.htmlįor more information also check out: en./en/innovation-and-technology/technical-glossary/elektronisches_stabilisierungsprogramm.html

The impression when driving is similar to that of a limited-slip differential in toned-down form. The level of pressure applied ranges from approximately 5 to 15 bar. This improves traction and reduces the tendency to understeer.

XDS applies pressure from the ESC hydraulics to the inside wheel to prevent it from spinning. However, XDS responds not to loss of traction but to the unloading of the front wheel on the inside of the corner when cornering fast. From VW directly: "The XDS electronic differential lock is an extension of the familiar EDL function.
