I have exactly the same problem with my 2005 Touareg. Can someone please tell me the correct part numbers. I was also wondering if I could replace the hoses with flex rubber tubing used on water coolant systems.
Thanks

 

Did you ever find out what items you had to order? I have the exact same problem with both hoses with my wives Touareg

 

I have 2005 and have same problem. I'm in Mexico and very hard to get parts without knowing exact name and part number.
Can anyone please help.
Thanks

 

Hi. It need to change the vacuum pipe, part 7L6 611 917 that goes to the secondary pump. Can anyone give me a hint how to get the connector to the plastic t-junction off, it is quite firm and i don't want to break another part.

 

This link just shows a rubber hose type fitting. Looks like a press on fit. No t junction on the part itself. Does it plug into a t junction?

The top end in this image, I can't get it off of the T piece

 

Do you have your replacement part? Maybe that will show you what part(s) you are supposed to move/squeeze/etc. in order to release the hose.

 

Good point. Yes I have the new part. It shouldn't be so hard, so I will take the intake pipe off to get to the connector better, and see if I can prise it off carefully and with less force, maybe lever it off with a spoon. The hard plastic connector has a rubber sleeve inside, but other than that I can't see anything fancy to squeeze or push. Thanks for your hint though

 

I got it off in the end after removing the air intake duct. The old part was badly cracked around the valve, which I had temporarily patched with tape.

 

Did anyone get a name or part number for this hose, I need to replace mine ASAP.

 

It is noted in the earlier posts above.

 

I have a 2004 Touareg and am having trouble identifying a which vacuum hose to order. My exhaust lit up and the independent mechanic determined that the cannister hose that connects to the manifold needs replacing. I live in the USVI and there is no dealer, so I usually have my sister send me the parts from a Kentucky delaership where she lives but this present issue is baffling me. The illustrations that VW sent are difficult to decipher for me (no mechanical training) and the independent mechanic, who is very good.

The illustrations that the dealer sent were 133-80 and 131-05. It doesn't exactly look like what the hose looks like in orientation under the engine. BTW, the mechanic gave me the number (12-13-23-0503) on the hose but it didn't correspond to a part number that the dealer had in the computer.

I am attaching pics that I took with the 2 hoses that I need identified, hoping that some of the Tregers here can help decipher the parts and/or part numbers that I need. If anyone has access to illustration 131-05, I think I need the hose labelled "8" but I am not sure about the other hose, in Image 188.

All input is appreciated.

The part number for the second pictures vacuum pipe is

1. 7L6611917N

I was able to find it on ebay - VAICO Brake Vacuum Hose V103660 7L6611917N for Volkswagen VW | eBay
