Oil filler and dipstick on 1.4 petrol

[Ridge]

I read quite a few threads about this, but most of them dealt with the 1.4 TDI which has a different part.

The 1.4 petrol has a combined oil filler hose and dipstick part. 8Z0115302R. Costs 250 € in Ebay. Pretty expensive.

I noticed that there's some oil below the oil filler hose. I haven't seen an oil leak myself, so maybe it's older. But now I noticed that the oil dipstick has actually snapped off from the metal connector pipe from the engine. I think it can be carefully put in place, but certainly the black middle connector part is missing.

Rather than purchasing this expensive part for a high-mileage A2, I was wondering
a) Can either the service hatch oil filler hose or dipstick cause a vacuum leak for the engine? I don't have any symptoms except maybe higher than usual fuel consumption.
b) Can these pipes be just plugged or do they have a secondary function? I read that someone had put a blind plug on the 1.4 TDI oil hose base. And then just use the second oil filler directly on the engine. Same for the secondary dipstick place. I don't know what to plug them with yet, though.

1- Has it snapped of from the top where it connects to dipstick, or at the bottom? Take a picture if you can. Mine is leaking very slowly from the bottom and snapped from the top where it connects to the service panel, so I'll need that part later too. For now I'd blocked it from top and removed broken dipstic too, as leaving it open can cause EML light and debrish can cause damage. Obviously you wanna know the oil level, so keep read on how I do it.
2 - Cars until 2001 can have a "hidden disptick hole", which allows you to have a simple metal dipstick, same as Polo 1.4, which doesn't brake and clearly readable, which is a really blessing. Your car might have it, so check it. I like the service panel idea, unfortunately most dipsticks were difficult to read and the plastic end broke off a lot.

This image shows the connected 2nd tube and dipstick already, so look for the same location but a bit lower. Should be a metal tube with a plastic cover on top, which you can simply remove. If that's permanently blocked, your engine don't have it anymore and you'll need a replacement. €250 euros seem really extreme, upgrade your account to market place and one of the breakers might be able to post you one for much cheaper.

I was going to write that it has snapped at the very bottom, but looking at my earlier part picture, it seems like it has snapped at the middle where the part changes from plastic to metal. So the metal pipe that I'm seeing at the bottom isn't actually a part of the engine but a part of the dipstick pipe.

I have the hidden dipstick hole with an orange plastic cap so that is a good alternative.

That's very useful indeed and that part might not be broken, but came apart? Either way that has to be sealed, oil will possibly leak out slowly otherwise.
Is the oil change due soon? If so, it's a good time to remove that piece and inspect it, as you gotta drain the oil first to do so.
I'd blocked off both front oil filler and dipstick holes due other issues, so as long as you got the 2nd dipstick option, and don't mind removing the hood sometimes, you don't really need them.

Oil change was last spring so due soon. What did you block them with? And I assume you blocked them next to the engine at the bottom.

I'd blocked both from the top, to get them further away from moving parts and the oil. As a temporary solution I put solid, non-fluff string of cloth, which only fit when I twisted them in, so I know they won't move up or down, needles to say, that'd be catastrophic if they got into the engine bay.
I was looking into a solution to remove the Y hose completely, and block it with some kind of plate, but it has to be custome made. A simple EGR blank plate won't do it, as it needs a seal too.
