Replacing cabin air filter and cleaning evaporator fins in 2021-2022 MS

I’m avoiding any water like the plague till I get the sock.You’ve gotta test it with a hose and biodefence mode on

Okay, don’t turn on biodefense but youv have got to test the dam with the hose and wipers. You’ll never know if you put it on right if you don’t.
And I haven’t seen any noticeable airflow reduction in biodefence mode.
But collectively, the dam and the sock are a $45 fix. It’s actually the Tesla way - use low tech and out of the box thinking to solve a problem!

don’t be so hard on yourself. The plastic is garbage. Right one snapped off on mine when the service tech replaced it.That makes me feel a lot better actually!!

Also worth noting: if possible don’t give up on this one as a warranty repair. I was able to make a case and I’m glad I did. This original revision was clearly ill equipped for heavy rain, the repair was very fast, and a mobile service tech simply kept the bolt on part that would have taken hours. The housing and filter snap right in after unbolting one electric (fuse?) that’s in the way.
Do you know if any water collects on top of the sock since it’s not completely tight and flat? I was wondering if just taping the prefilter flat on top of the air intakes might be better as the water will just run straight down. I wonder if it collected on top of the sock if it would eventually seep through or just sit on top until it evaporates?
I wonder when the use of this revision started on the manf line. My S was manf in March of 2023. Would the parts guy at the SC know?
Parts dept would probably not know for sure. Best way would be to look for yourself. Just pop off the upper cover and have a look.

I don’t think the updated part is going to fix the problem. A lot of water enters under the hood and will likely make it to the filters. Other potential solutions are outlined in this thread.
The updated part has certainly helped with my car.
A diversion dam and hydrophobic filter will also help. I still suggest starting with the updated Tesla part.

Just a few drops collect on the sock if they make their way past the dam. They dry up
How long have you had the updated part? I have a 2020 model 3 with same problem and design. The smell would go away or many months 4-8 months when I changed the filters but would then return. I think it takes some time for the mold to grow maybe.
It has been a few months now. In the past the smell would have been starting up again by now. I'm not convinced that it will solve the problem completely but I do think it has helped.
I do have the dam that @MFrunkerOG suggested but have not installed it yet. I suspect that the best use will be an inverted U shape surrounding the intake on 3 sides. I'm currently looking for some crushable material (modeling clay?) that I can use to determine the thickness of the space with the hood closed.
