After following this tread for a long time I finally decided to go ahead and install 3 out of 4 trays. Special thanks to golfdave, I literally just followed your steps, ordered the part numbers and did the install in less than an hour.
I love the result, and should definitely have been in my GTI to begin with!
Anyone noticed an increase in oil temperature after installing these plates?
Still struggling whether I wanted to remove all plates for a cooler oil temperature or keep it closed for aero effect, if any

Further considerations on fitting:-
Forum member “fullyswitched” suggests alternative VW push rivets for Item No.15.
8E0 825 267:- These allow you to pull the centre pin out using a right angle pick or pair or specialized pliers.
4D0 807 300:- These have a three position pin. The centre pin is more or less captive during use. The three pin positions are proud/unlocked, flush/locked, indented/unlocked. Once installed the pin pressure is released by pushing the pin further in to step over an internal notch & now the push rivet can be extracted by pulling. The pin is reset when the rivet is removed.
First, thanks golfdave for the excellent write-up. I am actually in the process of implementing many of the mods he has documented on my 2018 NAR Golf Alltrack SEL, which is why I ended up with all three types of push rivets suggested for the exhaust cover.
I do have one clarification/correction. In short, only use the type of push rivet specified in the catalog drawing - part # N 038 549 4 - and not either of the two alternatives suggested in the above quote. I thought the three-position rivet sounded cool, so I ordered that, but found that the non-expanding portion of the rivet was too long and allowed for excessive play. The same is true of the pick-removable rivet.
The specified push rivet allows for both a tighter and a more secure connection, as the pin is much tighter in the rivet than either of the suggested alternatives.
For those of you like me trying to seal off the engine bay from critters and the elements; VW changed the front left lower fender liner as production went on. My '15 Golf(8/14 build) has no hole(5G0805911AA) towards the engine bay, but my '17 GSW(5/17 build) has a hole(5G0805911AK). There's only a few AA revisions left in the US as they were discontinued and superceeded by the AK revision.
5G0805911AA(pictured is a cheap "oe replacement," not genuine)
I know my gearbox is very close to the liner which is why they cut out the bit....
mind you I might run the part number past my trained parts bloke (at the dealership)..see if it has "replaced" all previous versions...
I didn’t get the nuclear blast version but the thinner version. It has the DSG vent and has drainage holes in various locations. The one I got is 3Q0 825 236C
I was very reluctant to get the heavy duty version as he noticed oil temps going up a tad. I have NOT seen any temp increases since adding the thinner shield it hits 110 in the summer by me so it’s a valid concern for me. The “thinner” shield is the same thickness pretty much every car on the road and others I’ve owned over the years so it fit my needs perfect. It was under $100 for everything
I've noticed about 1deg C increase. I think I'm running the same version as you with the DSG vent on one side.
I've been tracking my Clubsport with the cover on all year with no issues. Ran on the weekend in 28deg C ambient temp and saw maximum oil temp of 125. I'm not tuned. I've hit temps this high before running the standard cover so I don't think it makes much of a difference.
