Replacement engine cover fasteners
 

I decided I want to put my engine cover back but now I am missing most of the fasterners (the ones that you push a little pin in the middle hole to make it tight), also missing one twist lock faster for the engine part. Are these Audi specific or can I just go to my nearby VW dealer and get them?

Not sure how universal they are, here are the part numbers:
 

Locking screw 8N0 103 531 (these hold down the cover for the battery and coolant tank)

Rivets 8N0 863 788 (various places to hold down engine compartment trim)

Combo (these are to hold down the front part of the engine cover on the 225 and I think on the 180 there is a place in the back):
Locking Pin N 908 011 01
Grommet 06B 103 638
Washer N 906 633 01

these?

Get the 42DD fastener kit. MUCH more sturdy and looks WAY better.

I think you mean these...
