Looking for updates as well. If I can turn my 34MPG into 36 then the $200 for underbody covers is worth it

Yes, it will block the drain pan. But, luckily, it attaches with screws and could be removed in minutes.
As for benefits off the Autobahn......reducing drag will also boost MPG, not just high speed stability. Granted, it may not be much from just the front shield, but for anyone that does a LOT of highway driving it could add up with all the pieces. This is why TDIs are common to have these, to paraphrase "It's the drag stupid"
If you took a hole saw to that pan to get access to the drain plug do you think it would add drag? I fear getting service with all these panels and then a lazy tech leaving them off.

Drag delta induced by a small hole will be in the noise. It might be a dirt magnet, though... to keep that from happening, you could use a plastic plug, like those used to cap tubing, or cover it with tape.

A small hole won't cause significient drag, but don't mind about two minutes work for your mechanic. :laugh:
All the VAG Diesel come with a pan like this - the mechanic will even don't recognize it as a retrofitted part.
Nice idea.
But only appropriate if you do the oil change on yourself.Again, we should not get carried away. ;-)

Whats the difference between R32 and Bluemotion undertrays?
The bluemotion tray does not have the rear most NACA duct, it only has the front two that route air at the oil pan.

Ah, sweet! Can you get it at a local dealer or ECS? Part number? Thanks in advance!
Large undertray from ECS- http://www.ecstuning.com/Search/1K0_825_237_P/ES316855/
It was on page 1 along with all the other part #'s if you need them.:thumbsup:
Not enough to notice, but used with other mods it all adds up. Also a big plus is it keeps the engine bay much cleaner.

+ BlueMotion TDI has some sound deadener against the ugly diesel noise. All TDI come with it.
Fuel milage is hard to qualify. There's almost no effect in town, but on highway undertray + rear
axle cover should increase mileage between 2 and 4 %. Not that easy to notice, but it is there.
Bear in mind the undertray will also keep the engine bay much cleaner as AF-MKVI and others said.
