If you have a Mercedes of this era equipped with an impulse code reader you will find a little numbered black box similar to the one in the pictured here in your engine compartment. It is located over by the battery and may have a black cover on it that can be lifted off. This is referred to as an OBD1 code reader. (First series of on board diagnostics)
If your check engine light comes on, you can use this little device to read the trouble code or codes. These numbered codes will let you know what part of the engine may be malfunction. Once you repair the problem you can used this little black box to “clear the codes” and reset the check engine light.
