This morning I was worried I was having serious tranny or bearing issues, with a scraping noise at low speeds only. Turned out the second under tray (the one covering the cross brace) fell off at the back and was rubbing at low speeds (and flying off the ground at higher speeds, so it was quiet).

I about had a heart attack when I saw vendor sell a fastener kit for $100+, for about 10 plastic screws with clips... And I used to think Porsche parts were expensive, Audi takes the cake ;-)
My problem is I'm not sure which I'm missing... on the rear of the engine pan basically. metal or plastic ? If I guess plastic, $36 with shipping for 2 plastic screws and 2 clips that cost $0.75 to make. I can't. I just can't. it's rape. Anyone use something else ?

I can already tell I'm gonna miss my lift, this car is low when you are unequipped ;-)

You must have had some work done recently since the fasteners to hold the undertray are pretty snug. The parts to fasten the tray are:

(2) plastic rivets - 8K0863788
(6) hex socket head panel bolts - N90775001
(6) rubber washers - WHT002227

If you are missing the speed nuts for the panel bolts:

(3) speed nuts on the x-brace to fasten to the engine undertray - 8K0805922A
(3) speed nuts (1) x-brace and (2) transmission support - N90610602

Reference for these parts can be found:
