Center cap falling off

[akarol]

Hey guys,

I don't know why but my rear right center cap on my 2003 Audi A4 stock wheel keeps falling off. I've tried about 5 different caps without any success. They usually stay on for about 3 days and then they're gone. I don't know if there is a specific method for placing them on. I just align them and push it in. Am I doing something wrong? The rim itself seems to be intact, so I doubt it's something on that end.

Any help is appreciated.

are all the plastic clips around metal ring inside caps still there?

Like JMVant is alluding to, there is a metal ring that goes inside the cap. Without this metal ring, the cap will continue to fall out since it produces tension between the cap and the wheel.

The center caps I'm using are brand new. The metal ring and all clips are intact. Am I supposed to just push it in or do I have to twist it a particular way? Also, to remove it properly, I place the "key" in the hole and do what?
