So ... you have been in Gainesville all this time and I just now am seeing you after I traded my car? We STILL need to do a get together regardless of weather I don't drive a beetle anymore.

About the part ... not sure.. going searching.

haha! Actually, I just moved to central Florida, but yes I was there for about 6 years. Funny, there weren't too many beetles in Gainesville that I noticed. Every time I saw one I would ask Ruby (haha, my beetle) if she knew it. Weird? Lame? Maybe, but entertaining. :D

Thanks for helping, I have tried looking several times but I am not even sure what system it is a part of!

Looks like a check valve for the vac. line.See if you can get any numbers off it,then call the parts dept.to verify it.

I'm 100% sure its your brake booster line It goes from a valve in the back of the engine to a big cylinder on the driver side right?

They fail easily, get yourself some good thick tubing from Auto Zone ($4) and patch it up, its going to be a tight fit but its easy enough to do.





another note, that could also be why you're having idle problems, the brake booster line pulls a vac from the engine to aid in braking and if it has a big enough leak it will kill the engine so a small leak might cause sputters/cel problems, replace this first before messing with the throttle body.

Interesting theory! Yes, your location is correct! I had jusssst replaced all the vacuum lines because I thought that was a problem. So, if I understood your suggestion correctly, I should replace the molded plastic piece with some hosing?

Yes, thats what I did. Make sure its a thick hosing though, a thin one will collapse. I think I used a thinner radiator hose but check the diameter of the broken one before or bring it in with you to autozone and they will find you one.

Just wanted to add finishing comments in case anyone else reads this looking for answers...

This fixed about 95% of my problems! I am still getting P0103 and can still hear a hissing (albeit MUSH quieter). The car still stalls when it is really hot out or the car has been running for awhile, I think the hose I have is a smidgen too big (1/2 inch). I am going to get a slightly smaller hose today after work and hope for the best - if there is not a slightly smaller hose, I will probably clamp the hose I have.

The hose I have is very thick walled so I am afraid the clamp will not do anything but I think it works fine until the rubber expands wtih the heat. If this is the case, a worm clamp may work and then the stalling may **hopefully** be stopped for good.

Just for good measure, I cleaned out the throttle body and cleaned the MAF. I have not seen any indication that I need to re-align the throttle body but I have had instances of this before ... not needing to reset things I mean. It may be because I have an early 99, before they changed a lot of the electronic programming. For instance, I do not need to go to the dealership to reprogram a new key or need a radio code after unhooking the battery. In fact, when I need to reprogram anything, I just unhook the battery for 20 min.

Okay that was long and mostly unnecessary but I wanted to post the possible solution because when I am looking for solutions I find a lot of unsolved questions and it is frustrating. Thank you to everyone that helped me with this!! I have my fingers crossed about the hosing but if it doesn't work, I'll probably post on this thread again.
