Thanks for the interesting write up.

I have a PP with this diff and have actively researched and followed as many articles as I can find.

I assume you have seen the Borg Warner video?

Thanks for the clarification of the XDS settings and interaction with the diff, that was very helpful.

Thanks dave.

There is so little information from VW on the VAQ and how it works.

I still think that Borg Warner video would make a good cure for insomnia. :grin: 18:30 to 33:30 is the most exciting 15 minutes. :huh: :grin:

golfdave, while we are analysing videos.

What do you make of the DAP;  "Increase the Traction on your MK7 GTI Performance Pack"

https://www.youtube.com/watch?v=3xlZ6gghqGY&t=119s

<lock electronics>
<acoustic measure wiring logic>
<increase traction>

I haven't changed this on my own car, what does it do?

The only thing I can think of is increasing the oil pressure from the pump, pushing the clutch pack together?

Cheers.

nicely done! thanks for posting

i tried watching that video a few months ago and it bored the tits of me too!


wonder why did they fit this if it heavier, more complicated, less robust and more expensive than a normal mechanical diff then?

Thanks...

er big cheap deal from Borg Warner??...buy 1,000,000 units get at 50% price??....

that's my only assumption...other than the usual sales pushing from the manufactures to the car brands whose marketing depts. say we can sell this & up-sell it as "X"...

I just find more & more marketing BS these days.....& having to dig down to actual facts takes more work as its getting buried...even the BW video is full of powerpoint middle management BS & padding......what they actually said on technical stuff could fit into half the video...

VAG seem to like the adjustable modes on their cars so I suppose this set up gives the ability to offer various modes where a mechanical diff is what it is.

The golf diff is really subtle in comfort or sport. I’ve felt it get a bit confused now and then on bumpy roads coming out of corners but overall it’s really good.

Very impressive research and write up golfdave. Unfortunately a bit wasted on me as I was getting lost just after the "Why do this" heading :laugh: Is there a one liner executive summary for numpties please?
