Does removing the rats nest cause any sevear problems with idle, or driveabilty? Thanks for the input.

 

I don't want to steal the thread, but want to join in. I am also having problems getting specifics. I am also very much interested in this. Please help us.

 

actually...it doesn't

i found that my car ran much better with the rats nest removed...

 

And i would love to know what all I remove to get it out....pic?

 

well... i mean its pretty self explanitory to remove. you rerout the fuel lines from the nest directtly to the fuel rails, then either delete the vacume lines, or cap some of them since i think some arent needed.

 

As long as you do it right, removing the rats nest will cause no problems with idle or drivability. I wouldn't recommend doing it on S5 NA's, since you have to do a bunch of rework to keep the 6PI and VDI working, and on S4 Turbos you have to do the same to keep the twin-scroll working but other than that there are no negative effects. Obviously you won't pass emissions...

 

SirCygnus is correct. If you have a NA then the process is easy. Ive fully finished my nest removal, only 3 vac lines, not including the ones for teh dashpot and the cold start stuff.

You pull the nest, run new fuel hose to its correct fittings, then run teh vac line from the pressure regulator to the other side of teh UIM. You can throw all the other crap out.

Now if its anythign else im confused and unsure other than a S4 NA.

 

soory for asking these but here in pr we dont use this word rast nest, and i really don't know what the rast nest is, can someone tell me, and sorry for not knowing

 

The rats nest is the bundle of hard metal lines underneath the intake manifold. All the vaccum lines and teh fuel lines run through it, its rather ugly to look at and can eliminate a lot of headaches in teh future.

 

Turbo is no harder.

 

Thanks for the boost in confidence about this. Having to remove the UIM to get to this stuff is B.S.

I would greatly appreciate pics (after removal) or specific threads for me to check out.

Thanks.

 

You are in for a world of fun with this car.
