If anyone can help me i would be very gratefull!

I bought an A3 1.8ts about 3 weeks ago and at first it was great, i would pull away then the turbo would kick in and i would really feel it.

Then....it started to hesitate and the boost would be intermittient. So i replaced the, What i think was the Diverter Valve (a bosh one, which is at the top back of the engine?)...and now the car is alot smoother but i cant feel the turbo kick in like it was? and i dont think its because ive got used to it. cos you just know when it used to kick in.

Would a faulty diverter valve make the turbo over boost? which would explain the car pulling so much at first?

Please help, i dont wanna waste my money paying for a rolling road test? by the way does anyone know how much this is?

Thanks For any input

Check your MAF and your DV. Which DV exactly did you get?
