95 E320 Check engine - No Codes

The check engine light on my 95 E320 station wagon is on.

Checked for codes at pin 8 & 14 and all appears OK (a single flash).

Any advice as to the next step would be appreciated.

Pins 8 and 14 do not activate the CE light
Only emmissions related codes from the diagnostic module do that.
Simply get those codes from the built-in led/sw on the same box.

The box should have a push sw and led built right into it at pins 2 and 4, respectively....

95 E320 Check engine - No Codes

Thanks Arthur.

I cleared it via pins 2 & 4.

Which I've done several times in the last few years. Guess I was just too quick on the trigger this time.

For general knowledge...the check engine light on this car has come on 4-5 times during that past 5 years or so...almost always after a 250 mile, 80 MPH run on an Interstate.

I'll clear it and it will stay off several months.

Something's wrong, obviously, but I figure not seriously wrong.

Thanks,

Allan Hobgood

95e320 Cel

Arthur,

The codes were 2 & 5.

I had a hole in an exhaust pipe replaced about a month ago...I'm guessing it has something to do with that???

Possible..

A code 5 on a 104 HFM is usually a blockage at the EGR tube , engine intake side.
There is a simple flow test in the archieves .. try " Egr hand vac" and look for my threads..

I have a simple question. Hope it will be answered. I have 1995 E320, SW, automatic. How can i find and fault or code. Meaning if there is any code stored in the memory how to retreive it witout the help of the OBD2.
Pl guide me as what knob to be pressed in the dash or in the engine compartment to know if there was any code stored.
I am new to this car. In my previous BMW 1995, V-8 530, there was a knob which i use to hold for 2 to 3 seconds and the problem us to come in the dash. If there was nothing wrong in the engine that also use to come that there is no problem at all.
The question is that do we have the same system in Merc 1995 E320?
