Hi! Does anyone know how to reset the computer to get rid of the O2 sensor light on a 1993 190E 2.3? Here's the info i have so far:

"There is a small computer inside of the car that triggers this light. It can be reset Or removed. The computer is under a plastic cover under the passenger side carpet (floor), it looks just like fuel pump relay. has a reset button on top that can be pressed to reset. Disconnecting battery won't reset."

I took apart the carpet, but could not find a button to reset...if anyone has pictures or diagrams, that would be great..thanks!
