I finally got up the gumption to run the Micropod through some steps, I had the pump run on the ABS module and it told me the steering needed centring. I only tried the ABS menu and it has not given me the confidence to replace the ABS module. I have read as many articles as I could on the subject but nothing covered my problem except one article did say that a stuck valve could cause a low pedal.
I do not think that there is air in the system as the pedal is rock hard at the bottom of the pedal stroke.
If I did change the ABS module I would have to bleed the system, the Crossfire manual says this involves bleeding the brakes, bleeding the ABS module and bleeding the brakes again. This means bleeding each calliper three times. I assume that the pump is activated to bleed each line when bleeding the ABS module.
The ABS works fine in the rain and on gravel, do I really need to worry about the low pedal? It is still some distance from the floor.
At my age I want the problem solved, going through the whole process above and not solve the problem would be a real downer. When I was younger I would have done it in a flash.
Any tips out there?

I saw these pages which were shown in the attached files in a previous John and Terry post. CLICK
I think the bleeding is done by activating the pump in the menu on a page not shown which is under the Anti-lock Brakes menu. Does anyone know for sure please.

The ABS on the Crossfire is a Teves ESP Mark 20 system.
