Hi,
Has anyone experienced this problem? I have tried everything to find the
cause and still nothing.
At low speeds (1st or 2nd gear and low engine rpm) when I go over a bump
in the road the brake system warning comes on in the center console
check system. At normal speeds >40kmh and at any engine rpm (even on a
dirt road) the light never comes on. This light normally indicates loss
of hydraulic pressure but the steering and brake system feel fine.
Could the Hydraulic pump be getting weak? What should normal pressure
be?

1994 S4 Six Speed, 180000Km

Cheers,
