LightRobin

have a fabia mk3, always just jacked from the folded edge, no issues as of yet and the cars been jacked up countless times this way

mk3 began towards the end of 2014, and i believe mk3.5 is the 2017-ish facelift, with a new infotainment, but the owners handbook would be the best place to consult for making these changes, as for the lights i know some specs have a "coming home" feature that leaves the headlights on for a few minutes after you get out of the car which might also keep the interior light on, my car doesnt have this option though

i wasnt even able to find the master cylinder on any of the usual websites, only on skoda-parts.com which sell at dealer prices from my experience. Maybe its the same part on older generations of polo/fabia but that would take some looking in to

while i cant help with the lights not coming on, you should be able to change the way the doors unlock in the cars infotainment settings, in my mk 3 its in car settings > opening and closing

Hopefully not, a new master cylinder will run 274eur not including installation (brake fluid ect) 🥴

Thanks for all the help with the brakes but what about the clutch noises i talked about, any ideas what those could be?, would it most likely be just the clutch and throwout bearing or could the gearbox itself be on its way out?

tried this, brake pedal seemed to feel the same This makes perfect sense to me, as well as ruling out the brake fluid being the culprit since ive had the pedal feel soft just after startup, (cold brakes)

yes, inside the cabin, theres a rubber boot where the brake pushrod goes through, its looks damp around that area, not dripping or anything, i didnt think too much of it

i tried looking through the side of the reservoir, also tried illuminating it with my phones flashlight to see it it helped but i couldnt fit my phone close enough, i couldnt make out a clear brake fluid level, the fluid level was just above the mesh filter when i took the cap off which seemed fine to me

Just one extra thing that just came to mind, very very rarely when I go to press the brakes the pedal will get stuck, and once I keep pushing it makes a loud *click* and begins to move again, completely forgot about since it hasn't happened in ages, also I decid d to take a quick look at the master cylinders from the footwell, the boot on the brake master cylinder looks damp and has some dirt stuck to it

Any other symptoms it caused/how would I diagnose to make sure that's my issue?

No it was clean on the inside and I wiped the area around the cap down before opening, the fluids looked good but the little filter cup refused to come out (wasn't seized in place or anything, I'm just guessing it has to be oriented a certain way to come out, played with it a bit and decided there's not much point) so I didn't get to look past that

Are the cheap brake fluid testers on Amazon any good? They just tell you the water content of the brake fluid and are very accurate from what I've heard, id want to avoid going to a garage out of pure laziness 😛

Hmm, my handbrake seems to hold well, I'm not sure what you mean by sheaths tho (I'm not 100% familiar with drum brakes but have a good idea) it is worth mentioning that when I went to work today (yesterday now) the brake pedal felt much much better than it did when I made the original post, could an issue in the drum brakes cause the pedal to feel soft seemingly randomly?

I've only owned that car since April (150000km), there no service record of it being done, I took a quick look at it and it looks clear and clean

yes it should be exactly the same, the polo and fabia share almost everything including engines, suspension, brakes, ect

Car Details: Year: 2015 Mileage: 166000km Engine: 1.0 mpi 44kw (60hp) Engine Code: CHYA Transmission: 5 speed manual So recently ive noticed a couple of clutch related noises, the first of which is a loud rattle when the clutch is up in neutral, seems to happen on and off as it sees fit, seemingly at random, sometimes it will rattle very loudly, sometimes it rattles just a little, sometimes it runs smooth as butter. My guess is throw-out bearing, although it could be a number of bearings in the gearbox. Also releasing the clutch quickly will cause a loud rattley noise too (think the clutch plates colliding) , so thats what we can refer to as noise 1 in the rest of this discussion. Noise 2 is moving over the somewhere in the vicinity of the clutch pedal itself (Right Hand Drive) , off and on it will make a "ploop" kind of noise just as I release the clutch, no noise when pressing it in. Best way I can describe the noise is think of covering the lid of an empty water bottle with the palm of your hand, squeezing it to pull a light vacuum and the pulling your hand away making a hollow popping noise. It happens on and off but I seem to only notice it when the car is cold, and goes away when warm. It is worth mentioning that today I was doing some other maintenance on the car and when I took the brake fluid cap off, the rubber inner lid was folded over itself in half, perhaps this has something to do with Noise 2 and more likely something to do with the next issue I will discuss. So my final issue id like some advice on is about the brake pedal, to me it feels way too soft and I can feel it bottom out with not all that much pressure. The front brake pads have plenty of life left although I have never checked the rear drum brake shoes since o bought the car at 150000km. To describe the feel of the brake pedal, I can push it just over half of its travel with almost no force, and it applies almost no braking in this zone, then it feels a bit harder for the rest of its travel before reaching a hard physical stop (if i push it down quickly i can hear it hitting something so it brake pressure stopping me), also when i release the brake pedal, the pedal seems to hesitate and lag behind my foot moving up. Turning the engine off and pumping the brake, it does build and hold pressure, and becomes rock solid as it should. It could just be me but it also seems that the pedal is firmer at some times than it is at others, originally i though it was temperature but on cold start earlier today it was soft as could be. Thank you so much for reading all of that if you made it this far, all thoughts are appreciated!

The pulleys on alternators actually have a one way bearing/clutch in them, so I'm thinking something may have gone wrong in there but who knows, it's the only other thing on the belt and the sound goes away when the belt is removed, also yeah I did check the belt, it looked fine. I should add that nothing visibly moves/shakes when it knocks, also it being loose wouldn't be affected by engine temperature (since it only knocks when warm)

Just a little bit of an update, changed out the belt tensioner today, fixed the rattle but the knock is still there, perhaps I'll try changing just the alternator pulley since the alternator bearings feel smooth and tight

the tensioner on my car looks like this one, same with the belt, https://skoda.7zap.com/en/cz/fabia/fab/2015-797/9/903-903030/ although thats for the 1.2L model

any ideas what i could do to test if its the alternator or the tensioner making the noises? also the tensioner at the link you sent looks different to the one in my car although the engine code and model year is the same, weird also why would it make noise only when i rev it in neutral, no noise if i hold constant rpms, no noise when decelerating, super weird

You read my mind, I was just looking for the part number for that, thanks

Bois we've had a break through, went and got new spark plugs today and got to work, changed them out and got bummed when the engine still ran the exact same, the old spark plugs were in pretty bad condition anyway so no biggie. The I decided to take the alternator belt off, which in my car actually has a tensioner even the the service manual says it doesn't, anyway took it off and boom, no more foreign sounds, engine runs perfectly, first time hearing about an alternator knock 🙃, now I'm not sure if its the alternator or the tensioner but my bets are on the tensioner seeing as how the belt is loose enough to squeek when cold, mad at the fact that I changed the rod bearings over a bad tensioner pulley but we live and we learn, just glad to have come to a conclusion, thanks for the help and suggestions

Just did a bit of research, you are indeed correct, it has a MAP sensor

I haven't tried unplugging the oil pressure sensor, will add to the list of things to try tomorrow, This engine doesn't have a turbo Also I put 5w-30 in it when I changed the rod bearings
