I ordered a 45 deg. silicone hose for mine but it was too short. had to add a pipe and a straight section of hose. Its holding up fine but is leaking a bit. looking for a better fix. I wont use the rubber hose solution as Im sure it would fail at the worst possible time. You know, like when your wife who wants the car replaced is driving it.

Im guessing that we could have some custom made but it would probably cost as much as the dealer.

Use the rubber hose-I had mine on for over 2 years,and most of that was with a tune......just check it every oil change.

My concern with the non-OEM rubber hose is the inside layer deteriorating and possibly coming loose, then some part of it going into the intake manifold.

This isn't as simple as saying "it's cheap, replace it when it fails". Not that I like the OE $120 hose either.. just that I'm going to try and find a silicon replacement.

If you find some silicone hose that fits,please post part#,price and where purchased from.Use the rubber one as a temp. fix if the OEM has a split (like mine did).

Default Had the same problem.....

Hose was split on the top. This was the one going into the turbo intake, right on the top right of the motor.

I was unable to get out so... I took it out and cleaned it really good with some carb and intake cleaner to get the grease off. Then I took some electric tape and double wrapped it really tight. Not my first choice, but it worked. No more hissing sound and no more LIMP mode.

Thanks...

Maybe go over the black electrical tape w/ some black duct tape.......maybe I'll try that-I kept the original one.

Thanks for the help, guys. I just picked up one of the NAPA 8460 hoses. I wanted to replace the clamps and the clerk suggested & sold me some heavy duty ones especially for diesels. I don't know if they'll make a difference but wanted to post that if any other newbies will benefit from the info.

Default One other option

I came up with another option for this intake hose section. I used to have the radiator hose fix. It blew out after 2 years, so I tried to find a better option this time.

In researching this, I found that McMaster-Carr has 100 psi hydraulic hose with a 6" bend radius - Perfect. The problem is their minimum order is 5' and with shipping it would have been ~ $60.

I ended up finding some 2" ID 150psi hydraulic suction hose locally that works great. In Rapid City we have a place called Industrial Supply Company sells it by the inch (.90/in). I bought 8" ~ $8.00 with tax. They also sell 150psi pressure hose but the suction hose seemed a bit more flexible.

The hardest part was getting a straight cut since there are wire supports molded into the tube. I used a chop saw with an abrasive wheel to get a decent cut - with a LOT of smoke.

It was a bit of a fight trying to get it to fit the bend so I used screw clamps to make sure it doesn't pull itself off.

Hopefully this helps the next TDI in limp mode.

P.S. I've got a pic, but am having trouble getting it to show up in this post. If I get it figured out, I'll add it.

Sorry, can't figure out the image posting thing. Maybe I don't have the right permissions or something cause I don't see the "Manage Attachments" button that the FAQ says I should have.

Summit racing sells a 2" - 45 silicone hose that is 6" long on each end. You can even get different colors! Got the angled hose out of it and 2 - 2-3" long interconnecting hoses. Win win.

This is the one I used on my 98', it has lasted years already, but it does sweat a little oil. I just wipe it off every time I do oil changes. It hasn't gotten soft and has never blown off.
