I have tried to source these connectors with not a lot of success.If you take a close look at the plastic connector there is half of a Bosch part#.I contacted Bosch and they came up with 2 part numbers;1928403137 for the plastic part and 1987280104 for the contact pins.I cross referenced these on the Bosch esi system and it gave me some Vag part #.So I ordered them from Tps,and to my surprise!! they were the wrong ones.At this point I gave it up as a bad joke.Hopefully this may give you another lead.
