Part numbers for climate control?? Help

[S£]

Guys, Can anyone help with the part numbers for the S3 climate control (facelift) unit.
which part number is for which, as there are a few,
I understand there is one that sits at the bottom of the console when you have the double din HU and one that sits in the middle if you have the single din HU and then there is two different shades of black, one black and one light Grey/balck

Mine sits at the bottom and is the darker black one anyone know the part number?? Pleaseeeeee!

basic part number is 8L0 820 043 but the last digits depend on whether you have heated seats (J) or satnav (K) or heated & satnav (L) or neither (H). Then there's the colour you mentioned, 5PR for Soul (Black) or B98 for Satin Black. Can you not remove it, the part number will be on it.
