Hi,

I brought a 2012 Skoda Fabia in May 2026 and the air circulation button (i think) when you press it or turn on aircon which automatically turn on it makes an awful banging noise

Has anyone had this issue and know what the solution is (other than leaving off)

Also the passenger electric window will open on passenger switch but close only on driver (is that common?)

cheers

Might be the air con compressor. Is it louder in the engine bay? As for the windows it may be a broken wire in door pillar or bad switch (they can get wet if window left open). The drivers side motorised unit controls the passenger side so if it fails both tend to stop working. Breezy Pete fixed my sons for me if its the window motor unit. New switches arent that expensive. Got an aftermarket one on Amazon for less than £10

Alasdair

thanks just wanted to ask incase common before take to pieces, drivers will shut it but not passengers side, aircon still works but i cant use wift left button switched on

The banging is probably due to that flap motor assembly having lost its positional feedback, a common issue for any flap motor on any VW Group over the past 20 or so years!

Or, the flap it is trying to move has ended up with restricted movement.

In its "lowest" form, this just leads to a knocking noise as the servo system ends up "hunting", at its worst, it will have forced apart the motor casing or even broken its mounting frame and some ones.

The weakness in these flap motors can end up being that they are never "exercised" enough, so the potentiometer track and/or its contact end up getting "dirty" as far as being able to make good contact is concerned, so it ends up being demanded to move from its usual clean position to a new position - but the track can be dirty at that point, so the positional feedback control gets lost - and the system ends up hunting back and forwards trying to get to its demanded position which is done by applying a known voltage that has been stored during initial setup - but it can't reach that exact position.

Edit:- no doubt someone will reply with help on how to replace this flap motor or at least help you look into why/what is causing this, I've only had, so far, one car with that issue, and it was a 2000 VW Passat 4Motion - and that motor in a RHD version of that car, was located too close to the side of the car to let me just swop flap motors, so that function remained U/S after it started to fail as I wasn't going to go the bother of removing the dashboard - I think Fabia etc is easier to work on though!
