[urq] Check System Control Button

[Max Hoepli]

Hi all!

I have a 1986 Audi 5000 Quattro, the little button for checking the warning lights in the middle of the dash does not work when pushing. The warning light indicates "OK" when I first turn on engine, the corresponding too low fluid level warning light for the hydraulic oil and for the windshield washer at different times has lit, the warning lights were correct after changing steering rack and adding washer fluid. When slamming on brakes one time triangle red warning light lit, installing new hydraulic oil accumulator solved that problem.
What could be the problems be. Please respond to all.
