    Yeah, I've had this in other cars too.

    The rule of thumb may be a bad idea in a Tesla now though. Since a recent software update the fans will automatically turn on to dry the evaporator about 15 minutes after parking the car if you have used the A/C. It'll probably not do that if the A/C was off when you parked ...

    I don't think HVAC is pumping nearly as much air as you think it does. I've been running it for the last 2 days, AC is just as cold as usual.

    I will try manually setting AC to high tomorrow to see if it has any issue with higher volume of air.

    I just brought my model 3 into Costa Mesa service center they wanted $220.00 to do the work!!!! What a joke. I turned around and left without getting it done. I am going to try and do it myself. I was using overheat protection with AC. :(.

    I tried the warranty angle and they said that is not an option. They also told me that three others were in for the same reason today! You know it's a big issue when the only service pricing posted in the service center is for AC cleaning. I should have taken a pic!

    The car uses the forced air HVAC system to cool the battery? It's the same circuit?

    There's a separate section that can be disconnect or connected to the freon loop, which cools the battery coolant resevoir (freon <> battery coolant heat exchanger). It doesn't use cold air (freon <> air <> battery coolant). But it does use the AC system to cool the battery as needed.

    If you look beneath where that aftermarket grill goes, you'll find that while the opening at the top is very wide, it almost immediately necks down to something like half the area or less. So it seems doubtful it will have a negative impact.

    Not an expert in fluid dynamics, but I guess the Tesla engineer must have had a reason to make the funnel as big as it is. ;)

    Wowzers, that price!! I wonder how much that filter lowers the flow rate over the stock one.

    $100 is a bit steep but at least it's for a pair. I'll let someone else be the guinea pig before I get one though.

    Hopefully CFM won't be an issue...

    lol. They want you to replace the filter every 12k miles. So that's over $800 for filters in 100k miles.

    Thanks for posting the invoice. My service appointment was pushed back a month as the filters were out of stock.

    The price of that, $160 mud flaps - it's true - there is a sucker born every minute.

    Thanks for the great post. I tried your method and seems to have worked.

    Last time I cleaned the AC I didn't get to replace the filter as they were out of stock. There was still a slight smell the next day and it gradually got worse. I've cleaned the AC one more time and replaced the filter a few days ago, and this time I can't smell anything so far. Looks like replacing the air filter plays a big role in removing the odor. (big surprise) I'm glad Tesla does not overcharge for the air filters.

    Agreed. I tried the ozone treatment but did not change the filters. It worked great for a few days but has since crept back somewhat indicating that there is some residual funk in the filters.
    Next stop - replace filters and re ozone ftw.

    Well, Tesla charges ~$40 for the filters? I can buy a cabin air filter for my wife's car for $10-15, so you could argue that Tesla is overcharging. :)

    I had same experience as others - I cleaned the evaporator but didn't replace the filters because the service center was OOS. the smell came back. I tried the technique of running on "HI" for ~30 minutes yesterday, We'll see if that works. On one hand, the car didn't get very warm, so I'm curious if "HI" actually heats the filters/evaporator that much. But I was doing it while plugged into a free L2 charger, so it didnt' cost me anything to try.

    Lasted about 3 weeks for me then slowly started coming back. I may run it again since I don't plan on doing the cleaning/filter replacement until summer is over in October.

    Tesla's are $17 each, but the car needs two of them. They're substantial in size. I think the price is quite fair.

    I just did the Klima Cleaner and got the replacement filters from Tesla for ~$34+tax. So far so good...

    Do be careful with the foam cleaner near the end though because I ended up blowing a lot of the foam away near the end of the can as it was only gas left with no foam. Also when I turned on the air vent after 20 minutes I saw some of the liquid leak through gaps at the bottom of the HVAC assembly.
