Cabin filter Tesla or OEM BMW

I’ve had my i4 for over two years. Maintenance costs have been $0 but BMW gives you three years of free maintenance. When I have brought it in, all they do is inspect the car, top off wiper fluid and replace the in cabin air filter.

I change my cabin air filter every 6 months on the 3 due to this SFL humidity. Can get 8-9 months with our Y.

I've just hit 40k km on my car. Only brought it in once to change the cabin air filter.

‘21 Tesla Model Y, I’ve needed an air filter change with coil cleaning, another coil cleaning I did myself. Set of tires at 25k miles. Currently at 30 k miles and only other thing I’ve done is refill windshield washer fluid.

I’ve changed the oil in my Tesla zero times in 15k miles, but I did have to replace the windshield wipers, and cabin air filter.

I've had to replace the cabin filter 2-3 times because of this problem. At first the smell would go away after replacing the filter, but eventually returns, usually when spring rolls around.

Production markings on the side of the filter as shown in the pics above indicate that this is a BMW OEM part. I can’t imagine that Halfords would be installing genuine BMW filters. There’s no way that they changed this.

That never got replaced, the filters still look white after 2-3 years in the cars I work on, this looks 5-10 years old.

That was not replaced in the last 5000mi. If you have an itemized invoice, I would check to see if it states what part was installed.
