After doing some searching, I have seen that the "TBB" seems to be the biggest culprit of boost leaks when you have a chipped 2.7T. The Samco hose is the sure fix. (or a Bi-Pipe from APR)

My question.......How vulnerable are the hoses at both ends of the intercoolers for boost leaks? I did not see anything here discussing the "must replace" themas in the "TBB". Are these hoses also available from Samco?

Thanks for all of your help in advance!


OOOO

 

The TBB & DV's are the main sources for leaks.

Some times the TBB will look fine, but have a slight rip on the seam, or at the boost sensor.

The IC hoses seam to not have the same problems & seam to be thicker rubber, then the TBB.

Yes, Samco makes an entire hose kit of the 2.7t.

2K,

Thanks for your expertise!If you do not mind, I would like to ask you one more question. My 2.7T is chipped and I do have a Samco TBB and Stratmosphere diverter valves, plus a Milltek exhaust (no downpipes yet!). My 6 speed tranny does not have the chip in it, What are the benefits of chipping the transmission?

Thanks!

OOOO

 

You have a 6sp Tip? ( I don't know a lot about A6's)
Well the trans shifts a lot faster, and will hold to redline, also has a higher redline (to match the engine chip)
I like it, but some don't think it does all that much.

 

Joeski,

What year are you? If prior to 2001.5, the other thing to watch for is the F-hose. It's another common failure point.

 

Southboro....

Great point! I am a 2000 and forgot about that little "F" hose. I have some extra cash laying around (YEAH) and I wanted to put it into some Samco hoses, but wanted to get the crucial ones first.

I am going to check on that "F" hose this weekend!

Thanks for your input!

OOOO

 

TIPs don't have a F hose just an FYI.
