Did a write up on this over on the MK7 forum.
Linky here:-

Slightly technical... :wink:

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?
https://vimeo.com/102644851
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:
-
Thanks to both above... :smiley:
I watched that BW video...fast forwarded that video...ages ago......& some of the info is bad translated stuff so not 100% accurate...plus they say at the oil is for life.....er NO...change every 3yrs...

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?

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?

er one liner.....read the sales brochure??.... :grin:

Golfdave - I’ve been looking at your thread for jack pads and also under body trim.
Do you know if these will fit the CSS?
Looking under my car it doesn’t look to have any more underbody panels than a normal golf?
Fancy them jack pads as the stone chip gets knackered using the sill jacking points

Under body trim...you would be able to fit the full cover engine bay skid tray or the thin areo tray...best from a GTE as allowing more air...
The panel from the rear of front subframe to the cross brace under gearstick...straight fit.....& the rear panel to the passenger side of the fuel tank covering the exhaust tunnel near the fuel tank....
Thats all that should fit the Hatch..& the jack pads should be a straight fit also..
You'll have to jack car up & take some pics to compare to mine for same ares..or dropbox them & I'll have a look?..

Excellent write up Dave. So what's the best setting for the xds on a PP?

Excellent write up Dave. So what's the best setting for the xds on a PP?
whatever you feel comfortable with & whatever the module will go down to...some rare ones (it has been reported) will do off (inactive), & most do "weak"...car can be set to "strong" from factory or usually a middeling setting, of normal/standard..

Cheers I’ll take some photos when I’m next home. I think I posted some ages ago on the clubsport thread but they didn’t really show much of the trim panels.
I’ve been under the car a couple of times and I did notice the front undertray looked very short though - nowhere near the sump never mind the subframe. The mechanic didn’t take it off when he changed the oil anyway!
The exhaust tunnel is exposed right along the car. I don’t think the underbody is any different to a regular GTI
Did you notice any increase in temperature with the larger front undertray?
I had one in my mk6 gti and the oil temp went up maybe 1 or 2 degrees if I remember.
-
Also do you have the part number for the GTE one?
Does that have plenty of cooling ducts? I saw one (assume diesel) and it didn’t have any ducts.
Is it same as mk6 - undertray and 3x additional screws?cheers

Yep you have the standard "half" tray...so choice of same thickness but full length to front of front subframe..."aero" tray..this is just three additional "bolts" to the subframe...you have to still use the 8 black screws that fix the half tray also...
Or thicker reinforce GRP skid tray..additional two brackets to bolt to chassis rails...& a further 4 bolts for the tray up front (7 bolts & 7 screws)
The front exhaust tunel tray wil be a stright fit & adds better areo...
GTE ful engine tray..has loads more ducts....I'll dig out the part number its in one of my threads....
EDIT>>>
Found it...
standard half tray:-
3Q0-825-235-A
https://www.ecstuning.com/b-genuine-volkswagen-audi-parts/front-belly-pan/3q0825235a/
GTE aero full tray
3Q0-825-236
https://www.ecstuning.com/b-genuine-volkswagen-audi-parts/baffle/3q0825236/
Obvious from looking at both photos that the "3Q0-825-235-A" is the standard half length tray.
The "3Q0-825-236" is the full length aero tray (specifically from the GTE Golf).
Neither is the "skid tray" as they are just thin plastic.

That’s great thanks for that
That looks similar to the one I put on the mk6 with a few vents added
Will ring vw and get a price.
I would put the exhaust tunnel ones in too but would be worried about heat
Thanks again

Don't worry about heat many people have done these & VW designed them for the MK7 Golf...even with a full skid tray & less openings in sunny south USA not much heat build up...& I have only seen +3C compared to before on hot sunny day 2hrs drive & then heat soak it..
Do NOT make your own cover to fit between the rear of the front exhaust tunnel cover & the front of the fuel tank.....a UK member on MK7 did....& I warned him not as VW don/t make one.....I was right...3hr drive on motorway he had heat build up & inside the cabin the tunnel got warm....too warm.....basically the air that goes into engine bay via the front try openings, exits the engine bay via the exhaust tunnel...getting hotter all the time..fitting the VW exhaust front cover forces this air around the front part of the exhaust to keep it cooler, then it really needs to exit out & downwards...
so just fit what VW make...

Its not something that I've got on my GTD, but I found the mechanical explanation very interesting and very well written.
I think you deserve great praise for putting in the time to write this up as it definitely is something that nobody to the best of my knowledge has ever done before.
Thank you Dave!

So basically it’s the GTE front cover and the long front exhaust cover I would need for my GTI?
I will look under and check the rear axle and exhaust covers will fit as I think the clubsport exhaust is slightly bigger than normal?
Thanks again
