Hi, thanks for your write up golfdave. I'm part way through following your guide. Front tunnel cover and MK8 rear aero covers fitted so far, noticeable difference in noise already and a jump in economy on my 1st commute. +4mpg was a shock but it must be down to other factors too.

The MK8 axle cover will fit perfectly once I order the right bracket instead of the left 😖 but I'm having trouble with the rear exhaust cover 5Q0 825 206 K. Has anybody else had an issue with this panel being too short? I've got a 2016 GTD DSG with sport & sound pack and my panel is 35mm too short and does look like it will also foul the exhaust if it did fit. The side body panels appear to finish in the same place as other pictures found and I cant find any other part numbers for different panels or fuel tank that might be causing the issue. The only thing I did notice was that my engine code isn't listed in control data which I assume is down to the exhaust placement?

Am I the only one who's had this issue? I can't find any reference of anyone else having the same.


Can't figure out what the problem is..... 🤷‍♂️ ...either wrong part given to you, or part letter has changed....parts as listed for the rear exhaust tunnel cover..

Quote from first page in thread:-

This item covers the exhaust area where it bends around between the fuel tank & the rear wheel, by joining onto the fuel tank & the big under tray for the side of the car. The part code is 5Q0 825 206C, although ETKA says the product has been superseded by version "K". The item still has "C" moulded onto it, & is stickered over with "K" on the ID sticker! ETKA describes this rear trim as "production ceased 2013, replacement part is K".

Got the problem thank you. The labels say 206 K but the moulded part no. is M which is listed as a sports van part and 30mm shorter. Fingers crossed TPS will sort it out. So glad I'm not going mad.

I have after much delay fitted the front LCA aero covers (5WA 407 118 and 5WA 407 117) to my MY19 Mk7.5 GTI.
A bit of extra work involved cutting two channels to clear the cable ties for the RS3 brake ducts.
Nice snug fit though.

I used the black plastic push rivets, part number, 8E0 825 267

You will need four of them.

Finally got around to installing everything today. A couple of comments:

The stand-offs for the front skid/aero guard are a pain. Removing the lower fender liner and then the horn made them go a lot easier. I planned on installing an iSweep Front Lower bar, but it did not clear (I'll be putting this up for sale soon if anyone wants it. Clears the SuperPro LCAs with RS3 ducts without issue. No issues with the Audi jack pads either.

Big thanks to @mech23 for the mid cover. The rear exhaust cover did not clear the ECS rear chassis brace kit. I had to notch the cover, and put the screw holders on to the main underbody panel, so the exhaust cover was on the bottom. Looks like it will hold.

034 RSB, Stern rear Chassis Brace, Rear aero covers - no issues at all

Overall very straightforward install. Thanks @golfdave for the great guide! Going to the autocross track tomorrow to test everything out. Now I just need to figure out if I can justify $650 for the Verus rear diffusor!

I did say:- "Now the tricky bit! You need to reach up & with great dexterity, place the brackets on the rear face of the crash bar mounting plates & insert the bolts with built in washers ".

;) ......""& with great dexterity"
has become a bit of a catch phase....in other words fecking damn near impossible!!..😬


& trying to resist scratching the itch that is the Versus rear diffuser.......good luck with that!!...:ROFLMAO:......only reason I don't have one is its only for the hatch!..

Anyway glad you found the guides helpful...!!

MK8 Golf hatch has a short axel tray similar to the below listed MK5 Golf one. However there is a larger rounder end shape near where the tray meets the fuel tank/exhaust. On initial inspection it looks like it will still fit. Part number 5WA-501-713

Hello, I am trying to piece together all the parts for the rear axle cover. I have a 2017 gti, and the mkv cover (1k0 501 713D) seems to keep coming up NLA. Should I look for the mk8 cover? I'm a little confused with the 2 sets of parts required listed.

Thanks,
Brad

Try the MK8 rear axel cover then...when I originally wrote the thread the MK8 didn't exist.....I do try to keep it up-to-date..& sometimes you can find the older parts for peanuts at scrap dealers/breakers yards..

Thank you golfdave for maintaining these articles.

From what I understand, the best mod to do is the rear mk8 shields.

I have an Alltrack so I already have the reinforced front plate. The next best upgrade would be the Tiguan subframe cover.
Is the short center shield worth it? For about the same price, after doing the Tiguan shield, how much pita would be to fabricate a bracket to have the longer shield fit there? For me it sounds like the Tiguan shield is more involved in modification and drilling.

i have a cat there as well, so short or long shield? Or no shield as the best improvements come from the front pieces?

thank you :)

As you have the AWD/haldex system you can only "factory" fit the front reinforced skid tray (you already have), the short front exhaust cover, & the rear lower arm rubber stone covers.

You can as you say remove (if factory fitted) the rear lower arm rubber stone stone covers & fit the MK8 aero covers.

You can if you want fit the Tiguan front subframe cover, but that involves drilling holes etc..

You could instead of fitting the front short "aero lip" exhaust cover, fit the metal cross tunnel bracket & longer bolts) to your cardan shaft bracket & fit either the MK7 plastic long cover, or the all metal MK8 cover.


As you have a cat there an all metal long cover would be ok, as even with the long cover you are not covering the whole length of the tunnel. This allowing for air flow to cool the exhaust.

If you don't want to "bodge" it then just fit the short cover as its an aero "lip", so will direct the air flow better..

Thanks for the reply. My dealer was somehow able to send both mk5 and mk8 rear axle covers even after stating the rear cover didn't exist anymore:unsure:
Is one preferred over the other? Or does one require less modification?

Thanks,
Brad

Well thats a turn up for the books!!

I think the MK5 requires less work...I can't remember as I haven't done it...somebody has done both & its in this big thread..so a bit of a hunt for it...
