Leaking ABS Controller Unit !!!!!!!!!! 850 1994

Sorry Billy Dee....wrong information.

The ABS ECU and ABS Modulator Unit (hydraulic pump) on a 1994 Volvo 850 are NOT located beneath the master cylinder. Therefore a leaking master cylinder (never heard of this on an 850) would not drip on them. These ABS units are well to the side of the master cylinder. You are also confusing two different problems. Yours seemed to be a bad ECU unit, but the original poster was describing leaking brake fluid without a malfunctioning electronic problem (yet).

Your suggestion about seeking out a salvaged part is prudent, however, regardless of whether or not it's the ECU or modulator/hydraulic unit.
