Try looking for 'Pulse Generator DSC'.  I can't see anything other than those on Realoem.  They are under the front and rear axle parts diagrams.

I think the DSC and ABS use the same part?

Sorry to bring back an old thread. All sensors now checked. It's not them.

Mention of an ABS ECU being refurb'd on this thread. Does anyone know what this part is and where?

Anyone have any other ideas?

See this image.  Probably under the bonnet near the ABS modulator block.

underneath your air box (3.0 petrol) all the brake pipes go into the abs pump and your abs ecu is the black thing bolted onto the end
6x t15 bolts copious amounts of swearing and it'll come out easily

Thank you both gents. So I went to see Jason and he said don't think it's the module just because the sensors seem ok. Bit of diagnostics later and the steering wheel sensor the culprit. Re calibrated and the yellow light has gone - not sure why it came up in the first place but thanks again Jason, top man! 

And a lot cheaper to fix than and ABS unit too....
