Does anyone know what are these vents under front seats?
The look is not so good and every time I notice them I feel BMW could have done a better job of integrating them properly. Currently, they just seems to be jutted out cheap plastic.

Did anyone notice same in their X5?

AC vents. Almost every car I've ever owned has had the exact same setup.

HVAC ventilation. Here's Audi's solution to rear floor ventilation, with aftermarket vent covers shown:

Yup, I think that's one design BMW hasn't changed in 20 years. Its a good thing I never sit in the back seat

[Qsilver7]

Floor vents for the rear seat passengers (#9 in the diagram of the air vents...there's one on each side {left/right} although only 1 appears in the diagrams illustration). When you direct the IHKA air distribution to the floor vents...these are the vents that send the air to the rear passengers.

The illustration below is from the e38/e39 era...but the design architecture is the same with floor vents for the rear passengers being located beneath the two front passenger seats

Whats wrong with them? They're efficient and do a job well lol

They are but when you notice them, they look like some cheap plastic that was over heated and contorted. Been that way since my first BMW. Probably the same part number

Wait till something gets stuck in it and you hear it rolling around. Happened on my X3. Had to take end piece off to stick vacuum extension in to suck it out.I couldn't get to it with it on.

Wonder if you can buy vent covers like the poster with the Audi did.

Apparently: https://ebay.us/ixHnAL (or this, same thing, for 1/4 the price: https://ebay.us/6cROGR).

[denniss]

you must be 4' tall to see these. i am 6'4" and i never see them as my seat almost all the way back.

This was the final fix on my Audi vents:



Don't know if BMW has similar, but guessing.

This looks neat!!

Its more evident under passenger seat. I never noticed it on my previous car as the seat construction was lower to the floor

It does cover the "ugly hole in the floor syndrome," but as someone mentioned, more to keep the assorted wildlife on the floor (marbles, M&Ms, purse contents, coins) from finding their way into the inaccessible HVAC ducts under the carpet. At least the BMW vents are somewhat raised off the surface - Audi's were flush with the carpet.

It looks good esthectically but will diminish the air output to the back seat riders, if you care. Looks to the eye to be about a 70% reduction of air flow. If this becomes an issue, meaning your back seat riders complain that they can't get warm, their feet are cold, yada yada you can alway take a dremel tool or exacto knife to it or just tell them to sit still, sit quietly, do it now and do it in a happy way and enjoy the plushness of the G05.

I mean hey, drivers rule!

Guess you learn something every day, I thought those vent were from the subwoofer… They personally do not bother me

Hasn't really gotten cold enough yet to see, but reduction will depend on air speed out of the vent, and I expect the air flow is pretty slow. The effect on the Q7 was basically nill, although the covers look like they would constrict air flow substantially. They do serve the very practical purpose of not allowing dropped objects to find their way into the HVAC ducts and under the floor. I expect the actual reduction will be closer to 10-15% at max heat, although I don't have a flow meter to measure. Not enough to make a practical difference, since it's a closed system and whatever reduction there might be will result in increased flow at another vent, but fluid dynamics was never my strong suit.

Just followed the Ebay links from a previous poster:

There are several vendors, and they all look like they're from the same place in China - I just found the cheapest that looked substantial.

My concern would be increased noise by making a “hiss” sound when the air is moving through the holes.
There is a advantage why most floor vents look like a open tube with smooth bends.
The open smooth design of the floor vents is to lower ambient noise and increase maximum air flow.

For example, half close the B pillar vents behind the front seats on our new X5 and you will hear them instantly when the air is flowing through them. Open them all the way up and they are silent.
