Correct part number for the alternator is 059903015PX. The tensioner number you have is correct.
As an aside, it's a good idea to update your signature to include some specifics about your car. That makes it easier for others to identify which specific model you're referring to, although in your case you did mention this in the first post - '2005 A8 D3 4.2 TDI (BVN)'
