If you want a more detailed explanation on why BOV's are generally bad for our cars ( some exceptions ) then read this..

The Audi turbo system is a closed loop system by which all unused boost that is spooled during off throttle and gear shifts must be re-routed within the system; it cannot be vented to the atmosphere due to the dependence on the MAF and ECU to properly read and interpret air flow dynamics within the intake tract. Therefore BOV's (Blow-Off Valves) are not used because they create a rich air/fuel condition (i.e. less air to fuel ratio) which will damage the catalytic converter, create soot on the exhaust pipes, and cause occasional misfiring (due to the purged air) which will result in ECU miscalculated timing adjustments and other errors.

For Audi closed loop turbo systems, a BPV (By-Pass Valve) or DV (Diverter Valve) is needed to recirculate the purged air and keep it within the intake tract.


hope that helps! welcome to the forums

the 2.0T uses an electronic DV, it cannot be replaced by a forge/baileys or anything like that...

forums : questions are asked, people answer
knowledge base: people search this database for the answers they need, no interaction needed..

For what its worth might as well stay stock on the DV on the 2.0T.

And wtf is happenin in here. I dont check the forums for a couple hours and all this **** goes down. Whys everyone b!tchin lately... were all jus tryin to learn more about our cars, each others cars, and just chill. So everyone just chill. There are noobs who get flamed and then learn and become older members at which point they flame noobs. Yea, noobs have no idea whats happenin... thats basically what were here for... to teach them about there car.. so teach, dont b!tch..... b!tches.

If you really want that sound check out ecs tuning. Forge makes one that works as an addition to your electronic dv specifically for the 2.0T engine.
