if the abs module is seeing a brief period of low pressure at the sensor ( i assume it has one internally) by the trapped air being compressed, it would/could throw a code.

1st rule of diagnostics is: whats the last thing you touched? in this case, bleeding the system.

I didn't (want to) see it this way, but you are absolutely right. Problems started with a lot of delay, but the last thing I did .... months ago ...was changing the brake fluid. What doesn't fit is the fact that the ABS light does even when out on a straight road without touching the brakes. In this case the pressure inside the system should be constant. In other words the assumed sensor does not see a pressure change.

But you're putting me on a lead ... it's not much work, and the fluid is cheap. And it's due for a swap in a few months anyway.

At least you have fluid. Seems rare in my local community.

I insist on a detailed, prompt explanation!

Been thinking of doing [maybe] a brake system flush. Unconvinced, but it would be a first for me in about 40 years. Every time I am keen on getting some DOT4 brake fluid for the little beasts, no stock. (*sigh*)

Didn't mean to get you somewhat excited Gecko.
