i have a mk3 16v gti and thought i would tidy up the interior buying a mk4 gamma head unit from the crap yard for a bargain 10 pounds!

. however the sticker on the side which usually has the code printed on it is long gone

. Does anybody have means of getting the lost code if i were to post the serial number stamped on the side?
cheers
