VW New Beetle Blaupunkt Code

Hi fellas, I have recently been doing up a new shape beetle that I got cheap its a Christmas Present for my girlfriend , anyway I ended up buying a cheaper still donor car and pinched the original stereo out of it as its better, I need the code and dont have any paperwork for it. I have tried online loads of Code Generators but none of them seem to work.
Could Anyone help out please.
Details on stereo are as follows:
theres 3 numbers
815 7 548 229 360
then what I think is a part Number 1 C0 035 186
then what I believe is the serial number needed but I may be wrong
VWZ1Z3Y5072222

Many thanks in advance if anyone can help me out
Cheers
and Merry Christmas to all of you
Paul
