Rather than continue to support Zombies, I thought I start a fresh thread!

SWMBO noticed the ABS light was on. I read the OBDII codes and now realise that the reader won't show me the ABS stuff... Oh well. Did a little Gargling and found various advice, so cleaned the sensors, the connectors in the engine bay were perfectly clean so unplugged and replugged.
Thing is, I don't seem to be able to find the sensors for sale on line in the UK. Anyone know where I can get them? I'm assuming one of them has gone bad. I don't have a multimeter to check the resistance (90-120 Ohms if you wondered).
