You're getting those codes where? It sounds like you have the wrong code list. The first thing to do is read all the pins/codes and get the right code lists.

The link below contains a thread that links a 169 page pdf document that covers the codes for Mercedes models from 1988 to 1998. Go to the second post of the link below for the pdf attachment. It should have the proper codes for your model.

http://www.mbworld.org/forums/e-clas...ult-codes.html

I'd attach it here, but the file is too big to attach on this forum.

The pushbutton/LED on the ancillary 8 pin plug is the DM / diagnostic module, which is also on pin 19 of the 38 pin. Look up the DM codes and other codes for a 124.034 at the link below:

Nope, still the wrong codes. It's on pages 35-36, and also here - http://www.startekinfo.com/manual/volumes/e3/8_1/m11.jsp Clear the codes, drive it a while and see what comes back.

19 fuel injectors open/short self adaptation

Don't address your questions just to one person, you want lots of people to participate. Plus you could misspell that one person's name. But go to the Startekinfo site above, find the code, look in the right hand column for the 'remedy/test". It usually points to another step - which in this case is going to be to build the code reader and read the codes on the other diagnostic modules/pins. 4 is air pump related, maybe a vacuum hose. Idle speed control is a system, could be lots of thing, worst case is a throttle actuator. But next step is to build the 38 pin code reader.

I find it hard to believe that so many things could be bad all at once. What kind of shape is the wire harness in? If the ECU is receiving bogus info from it's sensors because the harness is bad, it will start throwing codes.
