Afternoon all. I have a 2022 Superb 2L SEL Estate. It’s only done 1900 miles.

It has a slightly weird issue. Shortly after the AC is turned on, there is a loud thump/clonk from behind the glovebox area and the AC noticeably gets less effective. It will clonk again shortly after switching the AC off. When it’s on, and you go into reverse it will also give off a loud clonk again. When it works, it’s brilliant - icey cold - but post-thump, it’s just a bit limp.

It’s in warranty (just) and will be going in in a few weeks time. But would be super helpful if I can point them in the right direction!

Sound familiar to anyone?

Cheers, James.

Hmm, remove the pollen filter and see what’s happening

Put a bit of cardboard underneath the pollen filter then pull cardboard out and filter at the same time

Then have a nosey inside the fan blade underneath, sounds like something is restricting it, hopefully just a leaf Or so, have a look up too if something is there like a leaf

Thanks. Will google the pollen filter later. I presume it’s behind the bit of foam stuffed up under the glovebox?

Just took a quick video.

Behind this?

Ah. This.

That’s the one, the reason for the cardboard underneath is to stop any crap falling down on top of the filter/area from falling into the fan

Once you’ve removed that had a look around and hopefully you see something obvious

The thump is an odd sound, could even be a flap issue which you can reset by following this

If neither successful then get it booked in whilst it’s still in warranty

I found the culprit behind the pollen filter. It’s the flap you can see engaging here.

Nothing obvious that it’s catching on though. Least I can show them what it is now.

I don’t think it’s the big flap that’s making the noise it’s the other bit which is jaggerdy

At least you’ve found the problem, weird as your car is new, it’s almost like that bit should have some foam over it to soften the sound

Please come back here when it’s fixed and what they done to fix it, just in case it happens to others 🙏

Thank you, mate. I think you’re right. I’ll try and have another look tomorrow.

I tried the reset a couple of times and it doesn’t help, unfortunately.
