I'm from California now living in Cabo San Lucas. I have a 1992 300E great condition, checked out by reputable Mercedes mechanics prior to driving it to Baja.

Upon driving to Cabo and setting up my home. My check engine light came on. I brought it to a mechanic and he could not find any problems. Know one has the fdiagnostic tools down here to check the computer area network / diagnostic module.

I really need to turn the light off ASAP. It freaks out my wife.

I followed your instructions: Below are the results.

3-Hold the button down for 2 seconds, and count the number of flashes by the LED.

I had 10 flashes

4-Hold the button down for 6 seconds, the LED should stay lit for about 1 second (this indicates the code has been cleared).

I held down for 6 seconds, but the LED light was on the whole time it never turned off.
Did I do something wrong ?

I'm so frustrated can you help me. I'm not very knowledgeable about cars and feel like a idiot, So It would much appreciated if your could dummy up your answers.

thanks
