I have a used Skoda Fabia Mark I azq 1.2 and recently during inspection I’ve discovered that the hose marked on the image is missing.

Looks like it was there but it was broken and lost, as there were broken hose ends with marks of glue attached.

I couldn’t find any information online about this exact hose, what is it for and what does it affect? I’m going to temporarily fix it with regular hose just to seal the system from unfiltered air. But does anyone know if this part could be bought separately? All my searches were unsuccessful. What part number does it have if so?

Thank you!

The function of the pipe is cold/warm air intake. I can't see the pipe listed separately on the parts diagrams which makes me think it might be integral with the cover.

After further checking, the pipe is definitely a moulded part of the engine cover.

Wait, is he talking about that little vacuum pipe? Doh!

I guess you mean the narrow one, not the fat serpent?

Isn't it a filtered feed to the EGR valve?

Goes to the stub on the side of the EGR, via a flexible rubber hose that pushes onto a spigot just near the serpent mouth end of the narrow one in your pic.

Can't see that little pipe listed either but any vacuum pipe that will fit would be fine.

Oh, thank you all for the explanation!

 

Yes, I'm talking about the little one, I said it's a hose because it's elastic and detachable. Anyway I couldn't find anything on any diagram either.

 

Because my lack of experience I couldn't figure out what was its purpose. Now it's much more clear.

 

Looks like my temporary solution had just turned into the permanent one.

Vai até o toco na lateral do EGR, por meio de uma mangueira de borracha flexível que empurra uma torneira próxima à extremidade em forma de boca de serpente da torneira estreita na sua foto.

 

Sorry for digging up an older post @Breezy_Pete , but I've been looking for exactly about this for months. Same Engine AZQ. I've searched a lot, and the few manuals I've found, has not a Air / Gas recirculating system Diagram, to check the full system and hoses.

At a shop where I went to make a compression engine test long months ago, the mechanic removed the pipe that was supposedly connected to EGR, telling me that that pipe wasn't doing anything there. And I, without knowing, let him do it. I was only able to see, that the hose was around/near the EGR and the Engine cover.

So, Now I'm missing the tube, but worse than that, is that I've researched everything online and haven't been able to find where the tube connects. I suspected it would connect to the EGR, but I haven't found any documentation or information anywhere about it that confirms that.

So, does the missing hose it will connect to the engine cover socket marked in the photo, and then connects to the EGR fit socket ?

Yes, that is correct.

Many thanks. After several months, and plenty of searches, I finally got to confirmed information :) I didn't wanted to "test", since it could be not how that hose should be connected.

Just by curious, did you have any clue, about what can happen, due the fact of not having those hoses connected ? My car act a little weird, and I suspect that is something related to Air / E.G.R, or mix poor/lean. Can this be related ? tks

I do not think it will make any noticeable difference.
