I just purchased a set of f & r molded flaps from autopartswarehouse.com for $52.00, shipped. They are made by Power Flow. The fronts fit perfectly.
The rear require some cutting. Make a template before cutting. I don't think anyone makes rear flaps for the wagon without some mods.
Model # : Type 1 for front
Type 2 for rear

 

I was thinking of removing mine from my 2007 Waggie...if it looks good I may sell them...I'll let you know, if you still need them.

 

If mine wasn't a lease, you could have mine for free! I hate them. They scrape on almost all speedbumps.

 

I have a sedan, so it's not a solution for you but I'm with R36. Even with the most modest drop (OEM Driver Gear springs), I must scrape those suckers 2-3 times a day. I think a lot of times people think their cars are hitting the bump stops or fender wells, it's actually the damn mudflaps. My passengers are always like "WTF was that!?"

buy them new from the VW dealer ... its just $100 and comes with detailed instructions ...

 

Or buy mine for 1/2 that...

 

Your post was the kick in the pants I needed. Pulled those suckers off this past weekend. I will have to revisit some of the dips and bumps I know too well. But as far as looks go, man it looks clean with those plastic buggers off!

I have the same issue with mine, even if my drop is the original 15mm sportsuspention. Maybe there is a way to gently cut them in order to maintain the function, but loose the horrible sound? A 10-15 mm shorter mud flap might be the sollution.
