Yaris Mk4 Air filter intervals

[Cyker]

My Mk4 had its 2nd service recently ( 1.5 years old, already nearly 20k miles!!!), and I noticed some slightly anomalous things on the service sheet:

1) They changed the cabin air filter as part of the service!! Yay! Previously this was a check-only item and attracted a fee to change so I'd just buy one and DIY as it's dead easy.

2) The air filter was not changed... I was going to go yell at them but noticed on the service sheet it's now a 4-year change item?!?!? Is that right?!? When did that change?? On all my previous cars it was every 2 years (And believe me it needed it as it'd be black by the 2nd year! Now they're using this weird red-coloured rubber concertina thingy rather than the white cotton/paper air filter I'm used to in the old Yarisesisues so I can't tell if it's actually dirty or not... it's certainly a lot cleaner-looking than I thought it would be...! I guess the engine not running most of the time, esp. when stuck behind stinky diesel busses, helps a lot...)

Have a look at the PDF i sent you sometime ago

4 years for air and 2 years for cabin filter is extreme. If me I will check and get them replaced by myself. This is what I have done to my gf car at one year old and 7k miles , just bought a new cabin filter and replaced hers., fresh air immediately noticed. She doesn’t need to wait two more years for new filter , she will probably return the car before they replace it. 

[Cyker]

I wonder when they changed it... I'm sure it was 2 years for air filters and inspect and replace if needed for the pollen filter (Hence why I'd do it myself) so it must be a fairly recent change!

 

[Starensis]

With the emphasis on the global environmental impact, I would applaud the longer change intervals. Just need oil and filter to move to 20k and eliminate the 10k intervals.

[Cyker]

Yes because shortening the functional lifespan of the whole car is definitely worth the trivial environmental saving of a few filters...

 

[flash22]

I did look it up - every 10k miles or 2 years what ever comes first for the cabin filter, Air filter - inspect every 3 years replace on the 4th, plugs replace at 60k

I’m sure Synthetic oil and improvements in designs and materials, won’t mean shortening the life span of any car. This IS what manufacturers are being challenged with every day. 
 

They simply cannot bury their heads in the sand like some…….

Of course it will - Any VW owner who opted for the 'long term service interval', i.e. 20k/2yr miles, will tell you. In fact am I right in thinking VAG quietly stopped the long service intervals because it was causing such reliability problems?

The primary direction of current oil research is to reduce CO2 and improve efficiency, and they do this by being thinner and more slippery, but the fact is crankcase fumes will eventually cause the oil to become acidic and they can only put so much neutralizing agent in to stop it doing that before it can't neutralize it any more - This is why Toyotas that have had regular oil changes last so long, and ones that don't start to go wrong, as the acidic oil starts to damage the engine, especially the achilles heel, i.e. the timing chain!

Trying to reduce waste is an applaudable endeavour, but you have to look at the whole picture - If a few less oil and filter changes causes a car to fail at 80k instead of 200k the gains from saving the oil and filters is totally wiped out, and I'm sure we've all felt how much smoother a car runs after it's had a service - What is the impact on efficiency when running on really old oil vs changing it more regularly...? (I wonder if anyone's done a study on that actually...?)

 

Ironically long oil-change intervals was something diesel engines would have been better for, as the fuel also acts as a lubricant and the carbon that the oil absorbs and makes it blacken so quickly actually improves its lubricity, but alas that ship has sailed...

My mk3's handbook say change air filter every 4 years or 40k miles whichever comes first. Don't remember the timescale for pollen.

Fact is, once full BEVs hit mainstream - with no other options for ICE, some of the servicing sundries will disappear anyway. I certainly would only service my car to Manufacturers recommended intervals. If that was every 20k, with 60k on air filters and 100k on plugs, I’d be quite happy to do that.

VW - well, they’ve always been a pile of 💩.

Interesting... they must have changed it after the Mk2 then I guess...!

Same for my auris but these intervals are too long indeed. Since I do a bit of mileage I check often and I can tell you that for uk best to change cabin filter at 10k miles max or 12 months because the pollution levels, you will be surprised how dark they become and even not clogged with debris or leaves the tiny particles definitely restrict air flow plus the smell they emit it’s not pleasant or healthy for sure. For the air filter I do 20 or 30k miles max although if it’s dirty engine won’t get cancer but we can, pollen filter is the most important in any car. 👍

[Mojo1010]

The MK2 wasn't a hybrid so engine works all the time. MK3 & 4 hybrids so not on all the time, I think hence the longer mileage/interval. 

I changed the both the air and pollen on my MK3 at 4 years old with 38k miles on the clock. Air filter was dusty but not black. Pollen dusty, has some dry leaves on it but wasn't too bad. 

 

 

 

 

 

[Cyker]

Is the 4-year interval only for the hybrids then...?

Mk3 had non-hybrid versions...

I used to keep a cabin filter in-hand and change it if it looked dirty, as I got a bit paranoid about it after my first Yaris (The one that came with a filter full of dead wasps!    ), but as I'm usually running the Mk4 in recirc I don't think it'll get dirty so quickly...

Hmm I wonder if they do the charcoal ones for the Mk4...?

Is it easy on the tsport to change out the cabin/pollen filter?

As for some reason the "mechanics" who I have asked to change cabin filters on other cars I have owned seem reluctant to do so.

So I assumed it was very difficult and expensive on par with disarming a ww2  bomb while wearing a blindfold, judging by the pained expressions on their slack jawed hollow eyed faces.

Was that not the reasoning behind using paper insert engine oil filters instead of the screw on canister type? Less throw away material, i.e. the steel canister in addition to the filter medium.

From what I've read on here, that's reverted to screw on canisters, in some instances, with newer variant versions.

Feel free to change engine oil and filter every 20k miles. I most certainly will continue with 1 year or 10k miles, or more often, whichever car I own.

Personally, engine air filter and pollen filter, annually.

If I remember correctly, the engine air filter was an inspection at two years. Going back 6 years here. One of the things which I caught them (supplying main dealer) out with. It hadn't been touched. How do I know? I "booby trapped" the cover!

As I mentioned - I will follow Manufacturer guidelines with servicing, however, the less we service, the better for us and environment.

Good question, just looked it up, pop out the glove box press the tabs and slide out the tray

Tray - 88548-52010

Filter - 88568-52010 (Mahle LA 109, Hengst E2930LI or E2930LC (carbon)

Do check that it does actual use a filter first

It's really easy! The two hardest parts are a) Knowing where it is (Behind the glovebox) and b) Getting the glovebox out (You have to open it then push the sides in by quite an alarming amount so that the 2 thick tab thingies that stop the glovebox just falling out when you open it are released... then the whole glovebox will just fall out so you can access the slot the pollen filter goes in.)

The Mk1's had a carrier for the filter, but in the Mk2 onwards the filter just slots into the slot 'naked', as it were

Engine air filter has been 40k/4yr since introduction of 10k schedules back in 1999 with VVTi engines, the only exception being GT86 at 30k/3yr

Cabin air filters are 2yr/20k ( Soon to be every 10k/ 1yr with new carbon Activated filters coming from August )

Hybrid Battery filters are the latest filters every 10k/1yr for C-HR MC 2019, Yaris HV 2020, Camry HV, Highlander

As long as the dealers fit the things the right way round, as I found out to my cost when I replaced mine and got a magnificent improvement in my A/C when I fitted one the right way round..

[Cyker]

The filter has a massive arrow on the side with the word UP written next to it... even my dealer couldn't get that wrong!!  

 

[Mastermariner]

Changing the cabin air filter is very simple. Put a car mat on the floor to kneel on.  There's a small retaining bar on the side of the glovebox, squeeze the end of the retaining clip together and slide the pin out.  With the glovebox open, at the bottom  you will see 2 plastic flat hinge pieces. With the glovebox at about 45 degrees lift up the whole glovebox and they will pop out.  With a torch look in and you'll see a flat filter retaining bar, release the clip at one end and remove, slide out the old filter, check that your new filter goes in with the arrow on the side pointing UP. Replace the cabin filter retaining bar, glovebox and pop in the glovebox retaining clip. Taking it easy it's about 10 minutes.

Only if the word 'UP' is printed. I find many other filters have the arrow pointing in the direction of air flow, which is down!
