Brake Booster Vacuum Line Hose Pipe with Check Valve OEM for VW

If you get this for your beetle, try putting a little bar soap around the part that connects to the brake booster. It is super hard to press fit into place. Fixed my error codes and the car runs fine now.

Oem equipment, numbers scratched off as proof! Lol work great! My old like didn’t have the nipple on the side of the check valve so I capped it. Seems to work well

It’s a strange fit, don’t know if I’m supposed to bend it or something but it is very small and has to be stretched, it works like a charm though!

I live in California, where registering your car requires it to pass smog. I have a 1999 Volkswagen Beetle. On my OBD2 Scanner, I was getting code P0171 which meant the engine was running lean on fuel compared to air/oxygen it was receiving. The car was getting horrible fuel milage because the car's computer was overcompensating the excessive oxygen with additional unnecessary fuel. The car was also sporadically randomly misfiring. I though I had a bad oxygen sensors (upper and lower) and I also thought I may have bad spark plugs. Every time I visually inspected this hose (the old one on the car), it looked fine. However, when I decided to actually remove it to physically inspect it, it fell apart in the process of removing it. I bought this new replacement hose. Installing it was easier than removing the old one. After installing it and clearing the code with my OBD2 scanner, the car ran like new. I no longer had a code. I no longer had random misfires and my fuel economy shot up. Further, the car passed smog and I was able to register it.

Was a great fit a clamp for the rub hose would have been nice to have, the old clamp was destroyed getting it off. let’s add a small clamp it’s only pennies to add. could have saved me a trip to the store to get one.

Great and on the budget

Not a direct fit for a 2004 tdi but can be modified to work. Works great.

The plastic hoses on older VWs tend to crack at the barbed fittings and cause a vacuum leak/engine codes/poor performance. With engine idling, hood open take about a 3' piece of old garden hose, one end to your ear, other end to the hose/pipe and "listen" for a hissing sound, particularly at the ends where the fittings/connectors are. In a pinch you can tape up the cracked end and put a small hose clamp over it until the new one arrives...
