Which HDi fuel filter - Bosch, Siemens, Mahle - wot??

As motor factor's parts catalogues are generally wrong I thought I'd make a wee post here to clarify the matter. As far as they're concerned they're either Bosch or Siemens, which is clearly bull poo.

Early HDi's seem to have been fitted with the Bosch housing, later with the Mahle, but change-over times are rather confused. This is what Service Box has to say on the subject:

DW10ATED TURBO DIESEL AND BVA (automatic) AND MOUNTING BOSCH AND BOSCH DIESEL FILTER UNTIL RPO 09337 (09/2001) OR DW10ATED TURBO DIESEL PARTICLE FILTER AND BVA AND MOUNTING BOSCH AND BOSCH DIESEL FILTER UNTIL RPO 09337 (06/2002)
DW12TED4 TURBO DIESEL AND BOSCH DIESEL FILTER UNTIL RPO 09001 (07/2001)
DW10ATED TURBO DIESEL AND BVM AND MOUNTING BOSCH AND BOSCH DIESEL FILTER UNTIL RPO 09001 OR TURBO DIESEL DW10TD AND MOUNTING BOSCH AND BOSCH DIESEL FILTER UNTIL RPO 09001 (07/2001)

MAHLE FILTER DW10 (ATED & TD) TURBO DIESEL AND MOUNTING BOSCH SINCE RPO 08975 (06/2001)
MAHLE FILTER DW10 TURBO DIESEL AND SIEMENS ASSEMBLY SINCE RPO 09065 (09/2001)
DW12TED4 TURBO DIESEL AND MAHLE FUEL FILTER SINCE RPO 09002 (07/2001)

(note the overlaps)

As it's all a bit confuddled there's obviously no substitute for looking at the damn things, so here are some pics I just scummed off ebay:

Note the shape of the top (because that's the first clue you get that the factor has given you the wrong one. Again.)
