RE: We are NOT the A4 Forum, NO MORE BOV threads!!!!
Damnit!!! Read the first bloody post, lol.

Here is the skinny.
YOU CAN NOT RUN A BOV ON A CLOSED LOOP SYSTEM, UNLESS YOU GET A ECU TUNE FOR IT! End of story. If you don't want to spend the $1000 to get the car tuned, you can not run it. YOU WILL loose performance, you WILL get CELS, you will loose gas mileage, you WILL wear out a lot of expensive parts (cats, EGT's, plugs).
This will also happen with the Hybrid DV's. less so, but still happen.
So, stock, or just a chip, Bosh 710n. If you want more get the Forge 007. Spending $800 for Hybrid DV's is a waste of $$ to make your car run like POOP!!!

i know im new to audis but im not to turbo cars and i put 2 bov's on my 2000 s4 and it runs fine lost a little mpg but o well and it runs better down the highway the rmps dont surge anymore because the stiffer spring in the aftermarket bov's dont leak boost

RE: We are NOT the A4 Forum, NO MORE BOV threads!!!!
What BOV' did you put on? The issue is just that the MAF meters the air as it enters the intake. The ECU uses this to decide how much fuel to add, when you vent this pre measured charged air into the atmosphere it messed up your ECU. Even if the effects arent obviously negative to you, you MAY pay the price later on replacing sensors and such.
RE: We are NOT the A4 Forum, NO MORE BOV threads!!!!
Its been touched on a couple times allready on this page. If it is 100% recirculation it wont cause problems. Hybrid valves will be less of an issue, but problems can still occur. And complete vent to atmpsphere is not supposto be used in this car. Sure you can install it and your car will run but the s4 is programmed to have DV's not BOV's and you will more than likely be doing damage to your vehicle, even if it is not immedietly apparrent to you
RE: We are NOT the A4 Forum, NO MORE BOV threads!!!!

RE: We are NOT the A4 Forum, NO MORE BOV threads!!!!
Here is a brilliant idea... Instead of wasting money on VTA BOV's which will hurt your car later down the road why dont people just invest in some bigger turbos? Exhaust? 710N's? and MAYBE a chip... and instead of a woosh noise. People would hear a loud whistle and then a quick little snap from the dv. BRILLIANT
