First check the bulb is working, if not you have a power problem to the light I should think.

Are you sure its not just something simple like the bulb gone or its fallen out of the back of the clocks?

Hoping to resurrect an old thread,

these are my results, very similar.

Long story short, I removed engine and gearbox, the only thing on the brakes I disturbed was removal of front calipers, which I plugged the pipe's and re-bled on fitting.

At first road test I had the pedal jumping back at me from 10-0mph only. The red light and abs yellow light would come on.

I've fiddled about with the wires and float, the switch seems to work good. The pump primes and clicks of once under pressure.

I have swapped the ABS ECU for a spare, results are the same.

Now the red light (low pressure) no longer comes on when driving but the yellow abs light comes on at random and goes out at random. The pedal has a normal feel, I've covered 128 miles with no further issue.
