Now, my 1.9CDTi 150 is still ill despite having the mass air meter and vacuum hose replaced.

The local Vauxhall dealer is taking it in on monday to hook it up to the computers. He says it could be anything, but I was wondering if anyone can give me some ideas of the costs involved for replacing the following (including labour):

1) EGR valve
2) Swirl valve
3) Turbo

Thanks in advance.
