improving aerodynamics with OEM parts
Richn83:
I believe his was on the plastic clip like yours.

Anyone able to provide an ETKA exploded diagram from the rear end of the new Passat blue motion? I had a poke under one the other day and they had a half plastic half metal rear tray from the rear axle through to the back end of the body it sealed off the exhaust and right round the rear was wondering what could be done to mod it on to the GTI!

Found just this:

Thanks Bruce, I actually ended up with 12 instead of the rear part for the golf, it is a bit of a pain as I think it will just about foul the exhaust but plan to try fitting it once I get a second bracket and have some heat shielding I dont have a picture off it at work, but the lip up that should go up to the rear axle frame is right where the exhaust comes through.
The part 21 could well be the right part, the diagram doesnt look as big as what I saw under this car, but the diagrams arent always as up to date as the parts I guess the different PR codes might determine the size based on exhaust and saloon and estate. I need to get back under the rear end of a bluemotion and take some pics I didnt feel I could in a public car park as the owner might turn up and wonder what I am doing under his brand new car! :ashamed:
