Thanks for the explanation, and sorry for the panic
(I thought something had gone wrong because my later posts referencing to this thread showed up immediately)
I happen to be admin of a vBulletin board myself, but that is not in English (it's Dutch, actually) which significantly lessens the spam pressure.
To keep out automated registrations I installed a simple 'silly question' system that ask very, very simple questions that anyone who can type the URL can answer, but impossible to guess by a computer. Users report this function as more userfriendly than CAPTCHA, and in 3 years it only let one or two bots by. (changed the questions once they started getting through, clean ever since)
Anyway its interesting to see a anti-spam system in action that judges the actual contents of the messages by certain criteria.
And I certainly hope my post was useful. I see it mainly as the alternative for either coping with or disabling the error light.
For me personally the cheapabs.com repair service turns out much more expensive because of the shipping costs, but if we had a similarly priced service over here I guess I would have paid to have it done.
Regarding safety, I can understand if people think its unwise to 'meddle' with security systems like ABS. However, I reviewed the design of the unit and it turns out it was built with a lot of "fail safe" situations in mind:
1; The two processor units on the print are fed the same input, and process it in the same way. The results are compared and only used if they match. (i.e. if you break one or two wirebonds on the print, the module throws an 'internal error' code and stops working)
2; All valves are controlled by separate processors, that can determine if the valves are working or not. break a wire to the solenoid and it throws an error and stops working)
Another thing to keep in mind is that the repair shops that offer this repair commercially are not qualified by the manufacturer to do it, but still they do and give years of guarantee on it as well, without asking you to sign disclaimers, etc... Even if the whole controller is melted together with the soldering iron all that happens is a fuse that blows and then you
still have your normal brakes.
