For my car, a Jan 06 55 plate 2.0TFSI VW Golf GTi
Original DV 06F 145 710 B
I have just rang Colbournes Guildford, spoke to Sean in parts, who confirmed that for my car, according to Volkswagen UK's national parts database the correct replacement for the above DV is:
Revision D 06H 145 710 D
Furthermore,
Revision G 06F 145 710 G
Does NOT come up as the replacement to use for my original diverter valve.
If in doubt, use the above part numbers to check the correct DV for your car specifically.
