my a6 quattro is 1997 model, ~150000 miles on it. recently admist all the issues will ABS light being constantly on, even after servicing: Service oil sign doesnt go (probably mech forgot to reset codes) it recently just died on me. i would put keys in the engine and lights on the panel wud come on but car wont start, made scary whirring noices but wont start. this happened in morning (outside temp ~46F). the battery sign came on red and voltage on panel showed ~9V. a friend of mine kicked the brakes 20 times put key in ignition and the car started. completely baffled but scared to take it anywhwere that it may die on me and wont start. any advice !!
