BMW Repair: BMW Wheel Speed Sensor connectors, bmw wheel, wheel speed

Question
I have a '97 520I which I have had problems with the wheel speed sensor wiring on each wheel which have crumbled away.  I am replacing all but have found the connectors (grey plastic plug) connecting the wss to the main loom have also started to crumble causing me concern that i should replace them. Can you advise where these can be purchased as I see they are quite easy to fit. WSS are Siemens S103518002Z.

Answer
What I believe you should do is contact your local dealer to see if the connectors are availabe.Dealers may seem like the most expensive place to go but it would be the correct part.They may be able to help out finding other venders.You might also check a company called Wurth.They have many European connectors.I had misspelledthe company it is Wurth.
