No they shouldn't, I still know much older cars with original factory door seals never treated to any special treatment, as I've seen threads here and as a matter of habit I've used various stuff on the Fabia seals seals, Gummi Pflege is just German for Rubber Care so don't pay extra for any stuff just because the words are in German. I don't more likely to be some water held in the seal because of the hole but not enough to really get inside other than splashes, might freeze of course..

The leak at, with, in the area of, the rear door on my wife's 2015 Fabia rear door is I believe because of a seal inside the door (panel) same as the one from the Mk1 Fabia which was made many years before so no improvement, or successful improvement(s), made by VW in the time between. I've had much older cars than this, British made too(!), not "German engineering quality", that didn't have such a problem. I've had split door seals on 20+ year old cars, and others older still without split door seals. This is the Mk1 problem I believe is the issue on my wife's 2015 Mk3 rear door - (not a split door seal as with OP). - https://www.youtube.com/watch?v=0PjhoU1gEwk Note: I was wrong he doesn't do a vid on door seal removal.

VW do use a number of lower quality parts. Leaks on the inside of the rear door are common, hopefully yours is a god few years away from that if it arises.

Personally I very much doubt it'll be covered by a warranty but costs nothing to ask the provider. I would guess, don't know, the seal would just be pull off and push back on, possibly needing the heel of the hand or small rubber mallet, you might have to raise some plastic trims to tuck in but I don't know. A plastic pry tool would help with this or suitable spatula if you can get it in and out of the kitchen (I keep a couple of old ones in the shed for such jobs). HatBoYHarvey might have a video on this on his YouTube channel for the Mk1 to give you the general idea. - [ ETA: sorry, I was wrong there isn't a video of this ] HTH.

Part shows 2 /2017 in the dots, a locating raised part and the wings that keep the clamping clips with the cover, or should do.

2 years! Yet a "lesser" manufacturer like Kia can give 7, says something about VW's confidence in their products (given the quality of some of their parts you can see why) and how much they care about their customers really. Kia are no longer that much lower price in the UK but even when they were they were still quite good and longer warranty than the likes of VW and Ford. Neighbours have 18 and 20 year old Kia Picantos and next to nothing goes wrong with them or parts to replace despite being "cheap" cars from an "inferior" manufacturer to the (incorrectly perceived) higher quality of the likes of VW products. Out of the cars I drove, 17 year old Kia Picanto, 1 year old Nissan Quasqui, 7 year old Vauxhall Corsa, 8 year old VWŠkoda Fabia Mk3 1.2 TSI 90, I much preferred to drive the 17 year old Kia Picanto 1.1 (4 cylinder na). Problem with a new car, or newly restored or painted car, is you can become too precious about it despite it only being a lump of metal (and lots of plastics for modern cars) and the first dinks and scratches cut the deepest (as PP Arnold told us, and Rod Stewart and others). I've had loads of examples of this over the years and decades. We have to consider ourselves lucky that we can be so concerned about such unimportant tings as all these things can be sorted and replaced, or perhaps later just accepted and almost forgotten. Don't wash the car often and you will see them less, I can assure you of this, and the car still goes on, and lasts . 😁

I thought there were Škoda marking on the windows but with second thoughts I'm doubting myself, might be a false memory, too dark and cold to look outside now. By 5 years old you'd want to see on top of the annual "services" which are little more than engine oil and filter changes and look-see for any chargeable work which not even a proper engine service let alone whole car service, brake fluid change, spark plugs, cabin filter!, I'd like to see engine air filter elements changed at least with spark plugs but more often personally, air-con service if someone else is paying for it. If it was like it when you bought the car then the tyre should have been changed or condition noted on some report, depends how bad it is of course and if it was ever seen or tyres even checked in reality. Tyres are best changed in pairs of two (front or rear) or set of four or five. Unlike the engine relatively, tyres are one of the important parts/components on the car they effect the braking (the most important system on a car), steering and suspension systems, safety electrics (lights, horn. blower, wipers, etc.), windows and mirrors (and reflective number plates) (see and be seen) all more important than the engine (and transmission). No problem, see if the following can help, I reduced the size of the image or perhaps you can reduce it in camera's setting before taking the photos, having hi-res images is good for close up zooming but you don't always so much detail as 10mb or a lot less. I have also cropped the photo and added circles before rum4mo posted and said about your missing catches, good job the muck was holding it up. Orange circle is for what I guess to be some sort of locating slot I've never noticed before.

Quick thoughts some new batteries are better than others must be fully fitted well for consistent good operation (I've had a Dealership not properly fit a new battery even though it seems impossible to get it wrong, I've seen a battery in a door bel push fitted with the anti-swallow sticker still on the back of it unseen) change the battery in the other key (always use it as an alternating main key never as a spare or second to get even wear) synchronise the keys to the car (separately) details are in the Owner's Manual for the car. And as others have already posted.

Yeap I almost put that. Sounds are very hard to pin down, and yes they might be two separate incidents. Thing is the damage is from external source. Who knows what gets transported on our roads (and perhaps shouldn't or illegal) to fall out of vehicles and on to our roads and cars. Good thing is you are not in the UK for this, the cards are stacked in the favour of the motor trade and they spend a lot of money to ensure this same for Germany with their car industry it seems but I know other countries don't let them get away with so much, UK lucky to get 3 years warranty out of VW and other supposedly "better" car manufacturers yet they have to give 7 years in Sweden (and Australia I believe). Good luck with them. 👍

First photo is a bit too close up for me but the hidden bits on the car like that can look like a little child has been given the job of making them and putting them there but I suppose if they do their job and aren't seen does it really matter. The cabin air filter cover might just be gunked up with muck/fluff/bits I'd scrape that stuff out, perhaps the filter was never changed ("service" "maintenance" history should say if it has at least been claimed to have been done). The box with dots in it I think will show when the cover was made, it's not unknown for cars within the English motor trade to have parts from other car stock rather than original, not that it should matter on a part like that, assuming it's a correct part, best never to assume, particularly with the English motor trade, but to check. That I think is good, or could be side window. If a window has been replaced it might not have the Škoda on it, as I failed to notice when my wife bought her used 2015 Fabia when I found bits of broken glass their "valet" failed to when I cleaned (a very rare thing) the inside of the car soon after my wife first bought it.

The heater air-con idea might be wrong and it's something else. I could well be wrong but I don't think its anything hitting the fan or fan hitting it as even on lowest speed the fan would be going quicker than the noise suggests, it might be in the area of the fan (or not). As I ran 20-50 year old cars as dallies my wife got much better than me (not difficult) at identifying sounds and their origin locations, she listened and said the die (dice) in a cup thing and that it sounded like something was sucked in and moving around and then perhaps released or got away. The vast majority of luck I've had with the English motor trade over the decades has been bad (or worse) but I wish you good luck. The big ones are owned by the same lots that own the Dealerships and car auctions so .... Of the checks they claim to do well, you'd best check for yourself if they were done where you can. We had a member report he couldn't even get past VWŠkoda history off them, they said the lower price reflected its absence, you do however buy the car on present condition and as claimed. IMO you definitely want an ignition key and I personally would never have proximity stuff (keyless entry) these cars are already German marque over-complicated with intertwined complex computer programs and systems, the less of them the better for me. If you want to list the other tings that are going on with it members here may be able to help you with or about them, I can't stress enough (other members think I overstress this) how important the 12v battery state of charge is on these cars and how unexpected issues can arise from it (lots of threads and posts on these on here that are unexpectedly caused by low state of charge by the owner/drivers don't realise this, at the start at least). Good luck.

Yes but originally you reported noise to the front.

ETA: is the filter cover missing too or just not in photo?

Sounds are very difficult to locate. To me it could have been anything moving or being squeezed, crushed rubbed, only as example seatbelt stalk against something - but you last post suggests perhaps the possibility something has dropped or been pushed inside the heater / air-con inlet, outlet or in-between and someone has been trying to find it and get it out (perhaps before selling the car). If it was me and I bought the car through the English motor trade (gawd help us all) I would take this problem back to them, if they say they didn't know the filter was missing I might believe them as whatever checks they say they do they might not have, of course if they said somewhere that this type of thing is checked pre-sale then that's another you have over them if you want. If bought privately torch out, contortions in footwell to see what' up there and if you can fishing it out, same foe inlet end under bonnet, you could also check the drain holes are clear. Perhaps it's a fantastic-plastic VW part or part of a part broken or loose. " . . . mother's maiden name is . . . " The radio on is distracting to me, but I get your Lego brick, also sounds like a die in a thin plastic cup being shook or blowing around which might (or might not) suggest something in a ducting, the open end perhaps acting like an old horn speaker. If you are new to these cars, a tip, if your start/stop doesn't activate when it should then probably the 12v battery is too low in charge and if not dealt with may go on to upset the computers and they throw up all sorts of unexpected warnings, unseen error codes, and unexpected issues, even if the lights seem bright enough and the engine starts easily.

You have mixed the images in with your text but I take it the last two images are of your rear brakes and they do not look good possibly the bits of whatever very hard stuff you got stuck in the brakes causing the noises you had and have. With a zoomed-in look at the images front disc(s) images (first and second) to me and I am NOT a mechanic or expert, don't look bad if there is anything then it might possibly be from where and how long the car was parked up before your purchase, and/or after. Rear, well, they are as they clearly show. You could try your warranty but I am not sure they would accept the damage to rears. If there is still any debris in the rear(s) then it does perhaps need to come out, If you want to take the wheels off you could use brake clean to clean things up and perhaps who knows if you spray enough on you might flush out some tiny bits to loosen others. If taking wheels off these cars with stupid wheel bolts instead wheel studs I recommend the use of at least one but better two "alignment tools" to stop the wheel slipping and causing you possible injury (I done my back in for years with just the wheel slipping off 25mm to the ground, bloody silly bolts lack of studs). If your braking efficiency remakes good (much of which comes from the tyres, same for steering and suspension) then you could perhaps put up with the squeal and see if it reduces with more use of the car and brakes. If you believed the old saying, advertising and marketing about German engineering is/was good or high quality then you might have learnt now that diminished many years back. On my wife's 2015 Fabia changing the front pads and discs was the easiest I have ever done on a car, not that I have done many, and the rears were the second easiest I have ever done, a car 10 years younger might have more to it I do not know but I would imagine not a lot more if any. But you may not want to go that route for several reasons, in the UK the VWŠ Dealerships what a lot of money for this simple work and may well only offer the same quality of parts already fitted to the car already but I have no idea about your country.

@Marty_ro my wife's 2015 (hatch) also has a Bolero but the Driver "assist" displays less than your phot, do you also have the follow-the-car-in-front traffic-train active cruise control? I thought the 2D and 3D were joke references is there a difference , but then I have never understood why the "virtual cockpit" name. / term / description is used. We lost our broadband and telephone service all this morning, good job we don't rely on these computer systems in our cars. 😄

Maybe or maybe not, could just be a coincidence but to be sure have a good look at the brakes wheel side and inboard sides, all four if you have rear discs too. If you want to take the wheels off you could use brake clean to clean things up and perhaps see better, who knows if you spray enough on you might flush out any tiny bits. Brakes can get squeals and sometimes the squeals come and go. My wife's 2015 Fabia Mk3 has a trilling whistle from the brakes disc(s) touching pad(s) but it comes and goes. When I changed the front pads and discs I thought it would be lost but it returned, could be a number of causes but it is not enough to worry about or cause anything noticeable.

If you're not 'peterziherl' on OBDEleven forum then this was his final reply to his thread - "Twice they installed a steering wheel with the same defect, only the third time they ordered a new one from the factory (waited two months). Now it is 4,000 km and there are no more errors, and the system works flawlessly." As at post of Apr 13, 2022 at 7:20pm. Before that on the thread member 'massimo23; put about the trouble codes in opening post of the thread, including B17B8F2 - "These errors are found in VW TPI and the fix is to replace the steering wheel touch detection unit 5H0959542A with 5H0959542E." So personally I would ask the Dealership if there has been an update on the TPI for the change of part code to let them know you know about this in case you next get someone there that wants to start any run-around about it all as some at these sort of places can. Sorry I've no idea about extended warranties, as always you could go through the T&Cs and the fine print to see what is excluded and might be interpreted as a possible get out of jail for them. Many agreements even from very large companies that should know better and can easily afford to get things right can have errors and omissions or be badly written so giving possibilities of unexpected interpretation from either (or more) parties and often certainly not written in plain English (or even translated to). I would get the change done ASAP as November will soon roll round and if you need a replacement of the replacement (I don't know only saying) it might be out of warranty period only the part is covered by its own warranty and arguments about garage getting paid by who(m?) for the labour, and scan (do they ever no do a proper diagnostics other than a scan?), and wots a scan from them now £150 or summat like. Good luck.

Sorry, totally me misunderstanding and perhaps taking offence with your "sorry if this offends" I just took that the wrong way, I make many mistakes every day, probably every hour, that was another one I did put on my opening line that I could be wrong with it. I dislike macho male types but I was dragged up on rough council estates so the black wolf sometimes slips out unnecessarily. My personal (ex, I hope) troll is in this thread so perhaps I'm more briskly but that's no excuse to jump to conclusions with others. Please accept my apology, I misunderstood your post and was in the wrong with my wrong thought and interpretation.

I'm not so sure you are sorry, you seem to me to be more adversarial but I could of course be wrong about this, I'm not offended by you asking questions why on earth should I be. No one, sorry, I put it badly, what was in my head didn't get fully typed by me, I meant others have said their battery is good when it isn't. I will edit my post to make it clearer. The batteries are not charged to 100% every time, I meant each time of recharger use which would be very occasional especially over the cycle of charging and discharging of use of the car particular a start/stop car. We could also discuss 100% of what for what 100% is and when, and percentages overall, but why complicate simple things like what recharging that used to be just average driver maintenance, rather than it being stuff left to garages now or just replacing, good for the economy it might be. If I've missed anything, and you have already witnessed I can before, I'm not the best typists even one-fingered, please just ask.

That's great if you do 25 mile journeys and you have checked the battery's fine, Thing is it's not the same for all owners/drivers plus some are like teenagers living at home and not paying any bills with their electric use whilst driving and parked up. Plus of course you have a 2018 built car those with say 2019 and later may have much higher use. A number of times over the decades I have been told the battery is good [ ETA: - by others with a problem with their cars and I look at the cars - ] but when I check it isn't, loose battery terminal clamp(s) particularly after a battery has been replaced, by Dealerships, garages and retailers nowadays, but also often overtightened by someone with more muscle than finesse, or of course the battery is just in too lower state of charge for what is required. With modern by the time the battery won't started the car it has been severely depleted sometimes, depending on previous use, abuse and neglect by owners, drivers and those supposed to be serving and maintaining, may be beyond reasonable use recovery. Lights can look bright enough even when the battery is in a lower state of charge than the computers like. If you or anyone else doesn't want to buy or use a battery charger that is fine I'm just trying to prevent owners becoming part of the statistic of the number one cause of breakdown callouts and having all sorts of unexpected warnings and issues with their VWŠkoda.

I just zoomed in on the image and get a fright. it has "ITALY" on it! :yikes: 😆 It's an "Ambient Air Temperature Sensor" according to VW Parts 820 820 535 B. Certainly surprising but not totally unexpected that it should be something at a tangent given how over-complicated VW's computer systems are, possibly they out-"Simply clever" themselves sometimes. Or it might be something physically related rather than (only) computer. Well done to @hayeksbane on finding that and possibly learning how complex these things can be, but if you had a spare one you might already know a lot..

Thanks. You have already done well and a lot better than some other VWŠkoda owners who have replaced their batteries at 3 and 4 years use with newer models, VW in the Owner's Manual for my wife's 2015 Mk3 Fabia has to replace battery older than 5 years and IIRC it dropped to 4 years for newer models. ETA: I would expect the battery to last a lot longer with use of a battery charger maintainer particularly if the battery is recharged to full each time of use. 26k-miles in 6 years is a low average annual mileage but not as low as some but of course battery drain and longevity does depend on the use of the car and how much electric is consumed and returned to the battery by the alternator in car use or if an appropriate battery charger maintainer is used in accordance with the car's Owner's Manual and charger maintainer's instructions for distress and preventative rechargers. You could possibly get a lot longer out of your battery by recharging it fully now, as described, previously, and occasional as required or when you feel full rechargers. Or just replace and 'code' in a new replacement battery when required.
