New to the whole seen so may seem stupid please excuse my lack of knowledge hence i have dealt with N/A motors only.

We are looking to install blow off valves on a 2001 Audi S4, can any one point me into the right directions??

I have heard you cant on this model, i hope this isnt true !!

Thanks for the help in advance

 

Audi turbo system uses a bypass/recirculation valve called a diverter. There is no blowoff. There are hybrid valves available that will recirculate plus give you a bit of blowoff for the pshhh but it does tend to confuse the ECU a bit and is not ideal.

use the search and I'm sure you will find tons of information on the forums as this question comes up pretty often

 

So instead of having a BOV into the atmosphere, Audi uses the bypass back into the Manifold??

i think this might explain it much better than I ever could here



-not an expert, just an enthusiast

 

That did explain it much better, thanks for taking the time to find/post that for me.

Now i know where to go from here !!
