Does anyone know the right Condensor Drier for a VRS?

Because I'm changing my Air Con Compressor this weekend, I'm been advised from various sources to change the condenser drier as well.

Only problem is, it seems that there's several variants & I want to get the right one.

Firstly, I tried Eurocarpart/Carparts4less & they say they cant get it, but told me that the OEM part number was SAD012.

I've tried ebay & they seem to stock three different types - Hella, Delphi & Valeo.

They all look similar but I have no idea which one is right.

For example, there's two Hella ones listed on ebay, ones ~£28 the other ~£38. Both say they fit the VRS but it looks like the installation caps are different. FindPart.org lists that both these Hella driers fit the VRS. So confused!! :( :S

I really don't want to get one from a dealer, as I've been quote nearly £90!!

Does anyone know which one to get??

Thanks.
