I think the robotic arm that installs muffler pipes is hitting something while it is moving. Maybe VW will see this on site and go out and look for a place by robot that is missing paint from being hit. Ha Ha. Would like to know reason. Nothing is close that would need extra clearance. Maybe if you straighten pipe you will 10 more hp?

@ DainBramaged not sure the gap is back far enough or central enough to be the 4WD system as its to the side of the tank, but the prop must fit somewhere, revised saddle tank perhaps on the R?
Found a better pic of the underside, it looks like the aftermarket exhaust companies use it for the extra exhaust box in some cases. I have also arrowed a fixing that doesn't do anything.
In this last pic you can see a 1.4TSI with the exhaust area covered with a panel fixed to that spare fixing location on the tank, also another cover further down near the exhaust downpipe which is missing from the GTi. It could be that its missing from the car for the photo in the first image, but I don't think I have it either. Perhaps that one isn't advisable on the GTI or R but it possibly indicates some areas that could be covered with VW original parts if someone wants too further smooth flow underneath. Whether its for Eco reasons or less lift at the rear on track, small incremental parts add up I guess.

Keep going, post some more for those of us who do not have a car yet. Like learning about things most people do not look at!

Here's how it looks on 4motion Golf. Fuel tank is filling that empty space you have on fwd Golf in order to free space in center for driveshaft. Sorry for bad photos

On a road car, at stock ride height, road legal speeds, negligible
It's just there to look cool so kids can say "I have a rear diffuser like on an f1 car" XD
The parts linked for mk5/mk6 cars will probably not fit. All mk7's are bluemotion as standard as they have stop/start. Bluemotion is actually is the official name for the GTI!
The forward part pointed out by Emmett looks like 5Q0 825 229 C. I cant say for sure as I cant get a good view of it from the photo. There are different versions listed for the A3 quattro. It costs about £15 if somebody wants to try them. It says you also need the following parts to mount it:
N 038 549 4 Qty: 4
N 909 747 01 Qty: 2
The rear trim is the following part:
5Q0 825 206 D - For cars with beam rear axle
5Q0 825 206 E - For cars with 4 link rear axle
And you need the following mounting parts:
N 909 747 01 - Bolt - Qty: 3
N 909 591 01 - Speed Nut - Qty: 1
N 903 350 05 - Clamping washer - Qty: 1
N 038 549 4 - Spreader rivet - Qty: 1

Hmm......will have to look under mine again, & if there are gaps which can be covered using OEM parts........even more interesting!
Just ordered the rear trim panel to start with.
The part number has changed to 5Q0 825 206 K - For cars with 4 link rear axle. Total with fixings approx £14. Will see if it fits around the GTi thicker exhaust, or becomes an ornament in the shed.
Thanks again

Hello all. I'm the guy who started the mentioned threads about the Mk.V/VI aero stuff.
Thanks for the parts list. Looking forward they'll fit on the GTI.
These came with the same heavy cast steel arms as Xenon-equipped Mk.V GTI and all ED30 and ED35.
All 4WD have a pretty different rear section with a two-half "saddle style" fuel tank both left and right and zero space for a muffler near the tank as EB mentioned. If they have a center muffler, it's located in the tunnel.
Interesting picture, thanks !!

It's still the same design as on the Mk.IV, Mk.V and Mk.VI. A little front "skirt" with a gap and two "NACA" vents in the undertray, supplying airflow to the gearbox.
I never damaged any. However, all the plastic stuff is pretty cheap.
Same for me.
Which R came with aluminium control arms? The Mk.V R32 and Mk.VI R did not.

No, it's for a center muffler some FW models come with.

It has been a while but I thought I saw different rear control arms on a mk6. Maybe not aluminum, but I remember noticing that they were different and bulkier. Different car, but the Ford Fusion has rear aluminum arms that look good. FYI.

Not yet sadly, but I'll probably gonna get one next year.
Golf and GTI Mk.V and Mk. VI, Jetta, Tiguan, Passat 3C, CC, Audi A3 8P, S3, TT 8J incl. TTS
and TT-RS, don't matter if FWD or AWD - it's all the same.
On the other hand there are at least six different front control arms for the above mentioned
platforms, three of them steel and three made from alloy.
There's just one single rear control arm for any kind of PQ35/36/45/46 cars around there.

Its hard to see what kind of engine undertray it has in the picture above, but wouldn't it be a bit weird to stop the undertray before the sump, then have the panel covering the exhaust front section to improve air flow? Not sure...
Anyway here is (I think) an MQB platform underside (SEAT Cupra) probably the best pic i can find so far.
