I am diagnosing some TPMS issues, codes, etc, and have pretty much gone through the entire system. I'm still getting a fault for a bad antenna although I've replaced it, and it's showing it's receiving power/voltage, as well as the control module.

Question: Are these antennas interchangeable, specifically 4E0907277 and 8E0907277?

4E0 is what my car (2008 A4/B7 S-Line) originally had, and 8E0 is what I replaced it with. The 4E0's have weep holes where water gets in and corrodes the circuit board (REALLY dumb design🙄). The 8E0's do not have weep holes, and is why I went with it. Yet compatibility with my TPMS control module might be my issue.

Any insights?

Thanks!
