Hood latch 'ball' popped out, can't open hood.
On B6, it was possible to reach through the grill to take 3x 10mm hex bolts out.

Is there a way on the B7 to open the hood?
Only finding references for B6.

 

Very Easy. Jack up car, remove cover. Reach all the way up with finger or use a thick screw driver into the latch assembly (behind the backside of radiator) and push to the passenger side. Confused, look it up on Audizine's b7 forum.
