Hi,

Does anyone know how to replace the AC filter on mk4?
also are there 2 filters or just 1? i suspect there are 2 since there is the air flow system or what ever that called that supposed to clear the cabin air
can't find youtube videos for mk4 there are only videos up to mk3

thanks in advance

If you mean cabin filter have a look for your model and year on the Mann catalogue, also shows fitting instructions which come paper printed in the box with the filter. Choice of three qualities of filter too. - https://www.mann-filter.com/en/catalog.html

HTH.

The Fabia Mk4 has a single air-con (pollen) filter located to the rear of the glove-box.

If you refer to this forum discussion

and scroll down to my posting of 26 April 2024, you will find guidance on how to fully lower the glove-box so that the 'box' that contains the air-con filter can be accessed.

How to open that 'box' should be obvious and make sure you follow the fitting instructions that should come with a replacement filter as to which way up the filter should go.

(And make sure you get a good quality replacement filter!!)

I notice that a similar enquiry was made here

When referring earlier to the 'box' that encloses the air-con filter, I said "How to open that 'box' should be obvious" - but (having just done it) that may have been a mite simplistic.

The front cover of the 'box' hinges at its bottom edge and the next photo shows it partially hinged down. To open the cover when it is shut, the two 'flaps' I have arrowed in green need to be pushed firmly downwards (this can be done one flap at a time and it should be plain when the flap has unclipped) Then the cover can easily be removed.

This next photo shows the air-con filter partially pulled out and the directional arrow on the filter must point downwards.

In my 2024 Fabia Mk4's case, the Skoda-factory-fitted filter is branded "VALEO", but, as it also carries VAG data, it may not show in a VALEO filter retail catalogue.

The VAG/Skoda part number is 2Q0819669 and it's visually obvious that the VALEO filter in my car is the activated carbon type.

A 'genuine' Skoda filter is advertised here

https://www.skoda-parts.com/spare-part/2q0819669-cabin-odour-filter-skoda-39407.html

but GOOGLE-searching on 2Q0819669 should identify suitable (and less expensive) equivalent filters from Bosch, Mann, Mahle, etc.

There's not much simple from VW engineers, for various reasons it's usually beyond them.

I had to go into the internetweb to work out why I failed to do that "simple" task on my daughter's 2019 SEAT Leon Cupra - it started to look a lot like I was going to break something - proper "stupid" design.

To be fair to VW engineers - on the (UK) MK3 Fabia the cabin filter change is very straight forward, easiest of the very few different ones I've changed.

Still a pain in the knees and back getting into the front seat passenger footwell for oxygen-thieves like myself.

It would seem from previous comments in this thread that no owner (except me) of a Fabia Mk4 car has actually replaced the air-con filter.

Once it is realised that (as is commonplace) the filter is behind the glove-box, replacing the filter should be no more than a 5-minute task start to finish even for Mr **** Diyer.

It's like having sex while free-fall parachuting - it will be a lot easier after the first time but, if the procedure involved and any risks are not understood, it's something best avoided doing.

Interesting to see the photo with "cheaper"/cheaper(?) brand Valeo filter fitted from factory as last VWŠkoda Dealership cabin filter change on my wife's Mk3 it was a VAG labelled filter (now gone to the "recycling" (tip, hole in the ground)).

That factory one and that Dealership fitted one for my wife's car, appear to be the more expensive type of filter, rather than the less expensive "paper" types.

In the photo there's a nasty bit on one of the fantastic-plastic pieces of car, DIY adaption or VW's not so finest work, and some right rough finish to another (Temu) bit, obviously out of sight out of mind build philosophy.

It was DerekU that gave all the details.

Do you have any idea why you get duplicate " Quote in your posts.

To quote a section of a post you can highlight the bit you want to quote then you should get a black box with "Quote selection - as an example -

Sorry i taught i was replying to him, so DerekU if you see this thanks!

Regarding double qoute i dunno, i just click on the qoute button, maybe a bug?

I would love to have a replay button without qoute as quoting is not always required not sure why there isn't one

You can give a shout out to a member by putting an @ symbol at the start of their members name, example - @nta16 = @nta16 or if you Quote them in your post.

If it's a bug it must be with your machine or programs/Apps as it's only your posts, I have a recent bug with downloading pdfs from posts but others don't so it's not the Briskoda site with the bug.

I don't know what you see on your machine but I just use the white reply box under the last post (bottom of page for me) or top of the thread page there is a button which is a green box with white text "← Reply to this topic".

Hope that helps.

For Skoda Fabia Mk4 owners who like videos...

Although there is currently no online video describing replacement of the cabin (pollen) filter of a Fabia Mk4, the replacement procedure for a VW Golf Mk7 is similar as shown here (LHD car).

The front cover of a Fabia Mk4's filter-box has two retaining 'tabs' (not the Golf's three) and these can be unclipped by hand fairly easily without prising them with a screwdriver (as iI've seen suggested on other videos).

It's perhaps worth mentioning too that, when moving the glove-box upwards from fully-down to its normal position (2:30 time in the video) a degree of brute force is unavoidable.

This comparison test of cabin filters may also be of interest
