MY09 MKII vRS 2.0T CCZA Intake manifold error

Hi

I have been driving with the P2015 error for a few months but things seem to be getting worse.

I want to replace the manifold with a new part from US or the UK (because we get ripped off in Aus)

2 questions

1:  Is this the correct part number for my engine:  06J133201BD

2:  Anything else I should be aware of (or should buy)

I'm going to pay a local mechanic to replace it,  way to risky for me to do it with my limited skills and tools!  :)

Thanks for any advice.

Cheers

David
