I have an audi A4 98 Quattro 2.8L
After a high pressure car wash this thing dropped off the car, I'm not sure what they are called, but if anyone knows,please let me know
-what they are called
-where to buy them
and if possible, please let me know if it's possible to fix it myself. and what tools that I need.


This is the side of door. One of them dropped after splashed by pressured water.


This is another one that dropped on the same day

What I should do now? The screws that locked them seems to have badly rusted and I think I need a new set, but don't even know what they are called.

 

the first picture is of the mid door moulding. and the second picture if on the lower door moulding. both can be purchased through ecstuning.com the upper moulding will have to be painted.
