Would you believe......?

Last year's MOT, new ABS reluctor ring on f/n/s. This year new sensor on f/o/s and r/n/s. All the lights went out (the three friends!) cleared faults and MOT passed. A week and about 100 miles later, buzzzz of the Traction Control and the three stooges are back. Brake light and HDC switches both ok. Looks like another plug in to see which sensor it is this time, unless any other suggestions............:doh: (2001 TD4)

I think I probably answered it myself anyway in the question. It's the front left sensor air gap. No reading on live datastream so here we go again...............
