How do I know if my blow off valve is bad?

Can a blow off valve damage your car?
The simple answer is NO! A Turbosmart BOV or BPV are designed and engineered to improve the performance of your turbocharger system and NOT damage your engine.
Do you lose boost with a blow off valve?
You will lose boost by getting a new bov only if you install it wrong or if you get a bov that doesn’t hold as much boost as your previous bov was holding. If you get a 1g bov, it should hold between 17-20psi before it starts to leak. It is not adjustable. If you get an adjustable bov it may be able to hold more.
What happens when a diverter valve fails?
Car is running rougher than usual Among the most noticeable signs that the air diverter valve is damaged is your car running sluggishly.

How do you check a diverter valve?

Can a DV valve fail on an Audi A4?
The DV that comes stock in the B5 A4 works just fine for a stock setup, although it is made of plastic and can fail over time. An indication of this is if your engine won’t hold boost like it used to. Without a boost gauge to monitor your engine it’s hard to quantify this, but the loss of power should be noticeable.
