EDIT: Pretty sure I clicked on Skoda Octavia mk1 section of the forums but brain derped 🙃. Move the thread. Sorry.
I've been looking trough the engine information, engine explosion diagrams etc from Elsa and wiring diagrams and I just cannot figure it out.

What's the connector for on the air hose (pipe between air filter/MAF and that thing that flaps up and down when you press the accelerator)?
I literally cannot find a airhose with the connector on my typical go to part websites, everything that is sold is sold without that connector.
Every OE number leads to hoses without the connector.
But they can also occasionally lead to some chinese crap on ebay or amazon or shady russian websites that does have the connector, but I don't want to buy some low tier hose from some random company.

There's also smoke coming from where the blue line on the picture is which is why I'm considering a new airhose as I was doing the cigarette trick.

I blew in around 2 cigarettes of smoke so quite alot to help find vacuum leaks. Cigarette smoke was blown in from the air filter end of the airhose (took it off the MAF sensor).

Can this be a vacuum leak of some sort? Car accelerates poorly and I get intermittent P0130 faults despite a brand spanking new Lambda Sensor (Bank 1 sensor 1) that has been in use for about a year now (NGK). The fault appears 1-2 times per month.
There was also a puff of cigarette smoke coming from the oil dipstick which I caught by accident as I always check the oil level at the end of a cold engine test/inspection, oil level is roughly half of the dipstick measurement.
 

Oil measurement and the cigarette trick done with engine cold. The car had been turned off for 4-5 hours before I tested and was as cold as the ambient temperature.
Car has lived exclusively in Sweden and was registered there.

Things I've done to the car (relevant to the engine) since I took ownership:

26 June 2023: New MAF.
17 September 2023: New Lambdasensor installed Bank 1 Sensor 1 (precat) NGK brand.

11 February 2024: Termostat (thing that opens and closes depending on coolant heat) and the nearby coolant temprature sensor (Hella branded) on the same temprature housing has been replaced with new ones.
7 May 2024: Air filter change.
28 June 2024: Engine oil and oilfilter change: 4,4 liters of engine oil with specification

VW 502.00 (5W-40)

What's haunting my car?
Thanks.

Need thread moved to correct section as my brain derped.

Connector is a breather heater, I think, to stop moisture in the returning fumes from freezing and blocking the entry.

Thanks.

Alright, that's one confounding issue down.
Now just to find a new one. Which seems near impossible as basically nobody sells it

and VAG did not bother giving a proper OE number to it, so all of them just lead to ones without a connector.

If you tell me the vehicle identification number (VIN) I may be able to find the original part number for the hose.

Did this get resolved @BFQnightmares?

 

I am experiencing on my skoda octavia 1u2 bfq similar lambda problems (P0130) and also the intake pipe (with that what Breezy_Pete described as a heater) has a leaking/broken connector pipe. So i am also thinking to get a replacement part. I think the part needed is 1J0129684CH https://www.lllparts.co.uk/product/1J0129684CH At least if i search online with that code i find images of the intake pipe with the heater element. I have not ordered anything from lllparts but i assume it can be purchased there?

 

I am also curious if you got your problems solved...

Sorry for the very very late reply. Life beens busy.
No, I tried putting some epoxy along the blue line in my original photo but it did not solve anything.
Still have the Lambda codes. According to the inspector who inspected my car I also have P0135

Legit have no idea what the **** I'm gonna need to do to fix this ****, I have like a month left before they slap the car with a sticker that forbids the car from being driven on the road.
Going to do another smoke test to see if something else pops up, other than that and trying to figure out how to use a multimeter (I know **** all about electricity) to test things
I have no idea...

Just sick in general of all these ****ing cars with 5000 trillion wires and electricity and a million buttons and parts, next car I'm buying it's gonna be a old ****ing car with minimal to no electricity I'm sick of this bull****.
