1997 Mercedes Benz 420sl V8 Two Wheel Drive Automatic 133000 miles
Intermittent warning lights all come on at same time, They are " check engine" plus " low oil" plus " ASR". These problems do not really exist but 3 warning lights come on together and stay until the engine is turned off. After restart and driving a short distance, they will reappear. Local dealer has not been able to find the problem.
