Crackling Sound in A/C

[Simonyet]

Hi guys,

Does anyone get crackling noise after air conditioning run for about 1 min?
Or when you turn A/C switch off and turn back it on after a while.
The noise is like a popcorn, check this link:

I don’t think so. Because it is so cold

I've had both my previous 2014 and current 2017 F15s do this. The 2014 did it more frequently whereas my 2017 only does it randomly and can't be replicated.

Only difference between them was the 2017 has rear A/C where as the 2014 did not.

The good news is that I've never experienced any issues resulting from strange noise, nor lack of cooling performance beyond the normal sub-par cooling compared to other cars.

Nothing to worry about.

I have the same crackling occasionally on a 15 50i. No clue what's going on either.

Have you go to bmw workshop? I went to air condition specialist this afternoon and they said it needs to open the dashboard

I would not open the dashboard....the net outcome will be "working as designed" and there will be an introduction of new creaks and rattles with a strong chance of broken plastic tabs too....

Just enjoy the nuance of the F15 platform, the rest of the build is pretty solid.

I'm just leaving it alone I told my mechanic about it and we pretty much agreed that the ac is still working and just leave it alone for now unless something else happens.

No I haven't went to have it checked out as it goes away quickly, I will have to try and record it and take it to the dealer, but really not in a rush as its not a big problem.

[JMAN1111]

Will the dealer cover this? If not does anyone know how many hours of labor the evaporator takes? I have a 50i.

Have this same crackling from the vents for the first minute or so after starting the car.

I have it too when changing from cold to warm or warm to cold

I think they won’t since it is not a campaign. I went to independent bmw workshop a few days ago they said there is no electric movement in evaporator.

Any idea what it is or where does it come from?

is it possible that the sound from heater exchanger? i see the diagram, the heat exchanger location below the middle air vent. a bmw enthusiast told me that he has a similar experience in his E46 and it came from a heater flap that perform to close and the rubber around it already obsolete.
