Annoying Tapping and Boost leak

[Wilkeh]

Well, I've just had my car back from the garage after fitting a new secondary air pump pipe and now the car seams to have developed further problems.

I now have a very annoying tapping noise coming from the front of the end which does increase its speed when I rev the engine.

I also think I have a boost leak, but where can you tell where it's coming from? The car is fitted with a KO3s etc and the turbo's "spool" is very loud but now it seams to get to about 3000rpm and then it changes its pitch and sounds like air is coming from all over and then loses abit of power.

It never really did this before, its always pulled right up to the redline.

Can anybody shed any light? I don't know anybody local that has vagcom im affraid.

take it back the garage that fitted your secondary air pump, they could of left a boost pipe loose or a scondary ai pump pipe, also sounds like they have somthing rubbing against somthing like the aux belt causeing he clicking!
