Se hesitating when "on boost" leaky bov?

[dnz]

Whilst out in the car yesterday I noticed my car was hesitating/holding back when on. Boost and doesn't seem to have as much power as it's supposed to, it only does this intermittently and it's only started doing this a few days ago. I've read in a few places that it could be the standard recirculating BOV leaking thus losing boost pressure,

Had anyone else had a similar problem?

Also any ideas where I can buy a replacement BOV from and which ones will fit?

Is replacing it a big job and could it be done at home?

Thanks in advance

I fitted a Turbosmart Kompact Recirc Bov a few months back, much better, car pulls stronger so I think the original was dodgey. Also just fitted an AEM Short Ram Air Intake, fantastic mod - car has much more power and the Turbosmart keeps the noise to a minimum!

Don't forget to check your wastegate too...

A boost gauge would be a very handy thing to have and make diagnosis much easier. Cheap and easy to install
