F-Hose delete

[CliveH]

... i have a 'custom' N249 delete ... better than the standard one. (the Earl of Wakefield can bear witness to that )

I certainly can, M'Lord and a fine one it is too...

[CliveH]

[shineydave]

David, you have PM

[Harper--D]

Seems fine, it isn't difficult, about a 15 minute job when I have sorted the parts and how to, just remove the y-pipe to give access, cut the hard crinkle hose that feeds to the f-hose (just after the curved bit, leaving a 20mm length of the smooth bit to push the bleed valve on to, move the bleed valve back, and fit a t-piece. The bleed valve fits perfectly over the cut crinkle hose and then you need a reducer from the 10mm end of the bleed valve to the t-piece hoses (8mm ID) I think I have the right VAG hoses sorted, once I have it tidied up I will post a how to.

I have used odd vag hoses at the mo to make the connections, but I have the correct front one on order, part number above.

I cant see why it should be a problem, I will report back after some use.

Everything ok?? Any problems?
Dave.

Looking good Dave, no problems, just made the drive to Corfu (300 miles) and been in traffic etc round the island, no issues and seems reliable in all conditions and with the 45 degree heat here.

I have found the perfect genuine audi hose (off another model) for the rear from bleed valve to t piece, the correct diameters and shape, and the genuine one for the front from the RS4 is on order, I will take some pics and post the part numbers, cost etc when I get back home next week (posting from the hotel at the mo)

cheers
Nigel.

Sounds like a good fix to the dreaded f-hose then.

Anyone else tried it?

Any thoughts Doug?

[Doug_S2]

you will need a hose to go to the other one way valve for the fuel evap system, at the front.

[tdiquattro]

yepthat's the RS4 one straight to the manifold, 078 133 784 BG. should be a straight fit.

[CliveH]

any closer to a "how to"?

[Ads4]

Or a "Why?"

[CliveH]

Or a "Why?"

well the f-hose is one of the weak points in the boost system, and difficult to check for splits or tears without removing it (a complete PITA).

The Samco replacement is a good option, but if it can be "deleted" in this manner, then it seems like a good solution to me.

[Ads4]

Makes sense

[tdiquattro]

Ok chaps its been on for a good while now, took off the hose and checked, no oil deposits at all in the section leading to the N249, everything looking normal, no fault codes in Vagcom.

I will do a write up tomorrow!

Here is what you want to end up with... the blue line is the new route instead of going to the front of the manifold..

Everything is as it should look except the last pic should be of the front single RS4 hose to replace the F-hose, but here it is 2 bits joined as I am still waiting for the genuine hose from Audi. I will take a pic when it comes.
