The PP demands a kind of "recalibration" from your mind. It's diff is electronically controlled

The diff on the performance pack equipped Golf GTI is mechanical not electronic...
No no.... he is correct.... the Golf is the worlds first front wheel driven car to feature a Electronically controled Mechanical Diff. E-Diff.
The Ferrari F458 has a E-Diff too albeit a different type  :grin:

No, the stuff I have read shows the difference between the standard and performance pack is the addition of a mechanical diff (bigger brakes etc.) - the electronics remain essentially the same. The diffis not electronically controlled, the electronics operate on the brakes as a part of the traction and stability control programme.

I would say this is a way better system and a shame the Golf R didnt get VAQ with Haldex, XDS+ kills the brake pads / discs and heats them up quicker during sports style driving.
The Golf R will probably understeer just like all the previous generation Haldex systems  :sad:

I stand corrected; however, I should be very interested to understand exactly what the electronics are controlling and how because... your (pistonheads) graphic states "Electronically controlled, hydraulically activated" which suggests something other than direct electronic control of the diff...

As stated, they are sufficiently vague, as to how the control works to make their statement ambiguous...

The VAQ is essentially a transverse derivative of a HALDEX system. And yes, it's electronically controlled. The ESP sensors are predicting the car will slip, then an electronic signal is sent to the hydraulic pump which activates and pressurize the fluid which in turn is coupling the diff's plates to the exact amount it is needed to share the available torque to the wheels. It's a Porsche Torque Vectoring System in the front wheels. That's a VAG part-sharing byproduct which suits us!!! :smiley:

so does it need regular separate  oil changes like haldex? Anything said in the service book?

I don't have the service book as I do not have the car yet... But it's the usual bussines. Long life engine oil? Pah! Non changeable gearbox oil? Come on... I doubt it says anything. Of course I will be changing them at 80000km, as exactly was stated at the first generations of Haldex equipped vehicles (Seat Leon 20vt4, Audi S3 mk1 etc)

Bit of a promo video by an Aussie VW dealer but the CSG paintwork looks lovely in this one
