replaced the oxygen sensor. Check engine light went off, but on 1999 Mercedes-Benz SLK230

there is a little green light to the right of the headlamp switch that stays on. And the two red lights to the left of the headlamp switch flash and beep when i am near automatic doors or police radar. Computer problem???

I know, I laugh every time it starts beeping cause there is always a police car up ahead. Ok, your suggestion was to seek a diagnostic test?
