Alright guys i just recently bought a 2001 Beetle 1.8T and when i got it all the vacuum lines were brittle and some broken off. So i wanted to know if anyone had a picture of under the hood showing the vacuum line connections so i know where what hose goes as i bought some replacement hose.


Any help will be greatly appreciated. Thank you

Here is the basic vacuum hose diagram:

If you post photos of your engine, we might be able to help with specific hoses/connections, that are disconnected or unclear about. Then, we can see where you are at and maybe help get you back on track.

You might go ahead and print out the above hose diagram and we can go from there. Thanks.

A quick look at your posted photos; doesn't seem to show anything out of place, that I can see but it is hard to see where some of the rear vacuum hoses go to. There does seem to possibly be a nipple coming off the turbo inlet hose; that is blocked off or maybe not (are all the nipples coming off the turbo inlet pipe; connected to something)? Did you print out the vacuum hose diagram with the label page and trace each hose, to make sure they are connected correctly?

Here is a older thread; that has some photos and areas marked where things go, that might be helpful:

https://www.newbeetle.org/forums/questions-issues-concerns-problems-new-beetle/12670-important-vacuum-line-information.html

If after you inspect all the vacuum hoses and confirm things, if some connections, are questionable; you could post a picture of those and we can double check those connections for you and post photos of those areas, if needed.

Also, to make things clearer; you could do a basic drawing of the hoses/connections with the various part labeled (e.g. diverter valve, n75, N249, etc.) and we can confirm, that way as well.

Hope this helps.

PS: your secondary air injection pump and hoses; look like a rigged setup with rubber hoses and clamps, which makes sense, as the stock hoses crack/fall apart. There are some affordable way to get this setup back to a stock; if you are interested in doing that. That way you can get rid of the rubber hoses, zip ties, secure the pump correctly with the original rubber pump mounts and get things organized, back to factory install. The mounts are not expensive and can be purchased online for cheap:

I have used sump pump discharge hose; which is black, ribbed, flexible and installs into the factory ends from the stock hoses and it works excellent, they look close, fit the same as the original vw hoses. I bought this hose by the foot, from my local true value hardware store in the plumbing area but it can be purchased, at any hardware or home improvement store. It cost me $7 and I sealed the ends with electrical tape (you could epoxy it as well) and it works fine, still secure, not cracked, and it is a number of years later. I like to keep things stock and find; it is easier to work on things that way and the air pump, is vibrates less and isn't as noisy, when it is correctly installed in it's bracket with the rubber mounts. I had to do some funky hose repairs as well; until I got some silicone hoses that lasted longer and the sump hose, which finally fixed the poor quality/crack prone, secondary air injection hoses.

Yes on the main intake hose coming from the filter housing there is a nipple that has been plugged but it was like that when i bought it and i couldn't find anywhere that it could have went

And yea i printed off the diagram but it did not route anywhere near how it was already in the car and some of the routing points on the diagram i didn't see

Yep the Secondary pump hose was a hack job from previous owner but i have had a hard time finding replacements but if it can be done at lost cost i definitely want to do it as it looks messy and i hate the pump just basically hanging there.

On my car (2002 1.8T Turbo S: AWP engine code); the "nipple" off the turbo inlet, has a 45 degree check valve on it, then a hose which connects to a metal pipe, which goes to another rubber hose, which finally connects to the vacuum jet pump. Keep in mind, there maybe slight differences; in how the vacuum hoses and routing is, as my car is different year and engine code, compared to yours.

Here are some photos:

Comparing the photos, it looks like they plugged off the nipple; as the second metal pipe, it was supposed to connect to is no longer there. My car connects as follows: turbo inlet pipe, 45 degree angle check valve, small rubber hose, connection to metal pipe, small rubber hose, last connection, to the lower connection of the suction jet vacuum pump. The suction jet vacuum pump, is the small plastic piece; that is to the left of the fuel pressure regulator with a total of three connections to it ("Y" shape).

I can post a 2003 beetle that has a AWV engine. I do indeed have a 2001 Beetle with a APH, but my son is at work with it. I can post a pic of them later. But heres the 03 engine......

sorry, it was late last night before my son got home. You are correct saying they are different. The APH has that a single vent tube going to the PCV valve, as the AWV has two(two metal lines).

By looking at your pictures of seems like you have the diverter and regulator valves plugged in the wrong holes of the intake. Don't know how much it would make a difference though....
