My ac makes very weird noise

Sounds like a flap struggling to open / close to me?

How could I fix it it’s driving me nuts been like that for a long time

I cured a similar noise on a Peugeot climate system some years ago by spraying copious amounts of WD40 type lubricant into the air intake (after the filter) and operating all the various control options on the climate control. Whilst the car didn't smell too good for a few hours it did fix the problem.

 

I'll add that the vehicle was only worth a few hundred ££ and the quote to take the dash out in an attempt to fix it was more than the car was worth - you might think differently with your 2017 vehicle..........

 

 

And where do u spray it in

The only code for air con is this sensor and also how do I replace that

Into the air-con pollen filter box (it's behind the glove box - remove filter first) as the air is drawn past it'll carry the lube around the system.

I can't imagine a sensor would be making the creaking noise.........

I know but it’s malfunctioning and I would want to replace it 

Remember I did this on an old motor so do your own research before proceeding on the Superb. 

 

Sounds like a sticky / squeaking electric damper / flap in the vent system. Or the damper / flap is scraping the duct - perhaps when it operates going from outside air to recirculated air. Spraying said WD40 or something similar into the ventilation intake might do the trick but is a bit hit & miss. If you can narrow the noise down to a more specific location then applying WD40 or similar might be more effective especially if you can get a long straw to get to the working parts. I suspect a bit of digging & investigation will be needed to expose the offending item.

Give this a go

 

@Danoid I have tried calibration and I can still hear the sounds.
 

Hi Any solution how to get rid off this A/C vent issue? anyone?

There is a factory recall regarding this kind of noise from vents. It involves disassembly of whole front panel and flap gears lubrication. 

Anymore information you can offer would be great? 

I don't know the exact TPI number, but I did go through the same thing recently.

My car still had valid warranty, but the dealer mentioned recall.

Mine does this. 2016 model. It is annoying. I popped out the centre vents and the top speaker panel (has no speakers under it in my car) and sprayed a silicone spray which shut it up for a few months. But now it's back. 

I have the noise too. It sounds like un lubricated plastic gears grinding. Creaking. But too scared to go for a open dash job as I am almost sure it will rattle.

I have the exact same issue on my 2017 skoda superb groaning and creaking ac flaps when changing airflow i have raised the issue with skoda they can have a look unfortunately whole dash has to be removed they were willing to go halves on the cost but no guarantee what they find once said dash is removed its a 4hr job of which i have no doubt i'm assuming 2hrs each way at a cost of £400 said they'd knock it down to £200 but if it is something simple as lubrication i don't want to be coming back in 6 months time with exact same problem i've seen its not just the superb its others too i did receive a years complimentary warranty but it doesn't cover this unfortunately 

Skoda fixed it with spraying some lube. I don't know what kind but without removing the dash. 

Did they remove the dash?

Without removing dash
