THANKS FOR THAT OLIVE...IVE USED THE SAME MECHANIC FOR 7 YRS AND I ASSUME HE CHANGES THE BRAKE FLUID AS NEEDED..BUT I WILL ASK HIM...MY CRUISE CONTROL WORKS FINE...
SO HOW DID YOU GET YOUR PROBLEM FIXED??DID U REPLACE THE ECU??
I NEED TO HANG ON TO THE CAR FOR ANOTHER TWO YRS IF I CAN..SO HOW LONG DID U WAIT BEFORE GETTING IT SORTED?

I suspect dry joints etc on the ECU PCB.  It will not be related to brake fluid.

Is it safe? Well ABS won't work. Is it legal? Not sure what the law says about inoperative speedo.  Insurance will probably be invalid as well, as vital safety features (ABS, TC) not functional.

Thank u "theboy" one final question........is there any connection with the ecu and the power steering
because when the lights came on today there was a definite tightning which eased off when the lights went out or is this coincidence and something else is wrong..thanks in advance for any final thoughts on the problem...rod

If you have a 6 cylinder model, yes, as it has the ZF Servotronic speed sensitive power steering, and thus needs a speed signal (which is generated in the ABS system).

Get the ABS ECU read with Tech2 - you may be lucky and its simply a sensor fault. Unlikely, but always possible...
