Ok, I posted this in the TT section, but it seems that no one is ever there.....


I was looking into a BOV for an '01 TT 225 quatro. I heard that BOV's for these cars can be bad, and that diverters are better. Just wondering exactly what would be best.So far its stock, but a chip may be added later. I like the sound of a BOV, but donr know if a diverter would make that. And, what brands would be easiest to install on this car? I know some will bolt right up, and that would be a plus. Any help would be much appreciated.

...Mod. pointed me to another topic....

Personal experiance stories would still be nice though.

It's an ongoign debate. Most people agree that BOV's on Audi's are not appropriate as they cause you to run rich.

ya, thats what I have heard from several different people. But what about diverter valves? Whats the real benefit to that over the stock stuff? Is there any point in upgrading this kind of thing on a TT in the first place?

it's basically preventative maintenance. If the DV is holding boost then there is no need to replace it. Most people replace them as peace of mind.
