My garage guy didn't tell me the fault code – but he is sure it is the ABS pump. It needs to be rebuilt or I need to find a working one, because it's lighting up the ABS light so my car can't pass an MOT – despite being lovely in almost every way. Feeling very depressed about it. I've tried breakers, eBay, etc. to no avail.
As Wurly says, you only have to bridge 2 pins in a connector under the driver's side dash and the car will tell you what the error is; it's far more likely to be a sensor but follow this link to a visual tutorial of the same.
1. Use this link to locate/setup the jumper:

2. If you can't find the jumper, as I did, it may well still be located right behind the stereo which is where it would have been from the factory. If this is the case, move the centre console that has the handbrake/cup holder etc. All you'll need is a cross head, it'll take 2-3 minutes to remove the centre console.
3. Once you've set the jumper, use this link to determine what the error code is:
4. Turn on the ignition, but do not start the engine. The ECU light will remain on, on the dash, and then the corresponding failure section will flash, in your case the ABS light.
5. You'll have 2 sequences of numbers, for the ABS section each sequence will be quick flashes, so count the first sequence and then the second sequence. There'll be a 5 second gap at which point it'll either repeat the first error code if indeed there's only one error, or, it'll move on to the second code. It can store 3 codes at a time, but it's unlikely yours will be more than one.
6. I'll hazard an educated guess that it's a sensor and not a catastrophic failure of the pump, however, the code reading will confirm this.
7. Once you've finished reading the codes, or doing the remedial work, you can remove the pin from the jumper. However, if you're feeling clever, fit a toggle switch, as I have, so that you can turn the code reading on and off at will without having to mess around with a pin etc.
Out of interest, is it just the ABS light that comes on or do you get other warning lights, 4WS for example?
