For my M104 (93 300E) when using the make-it-yourself reader, after reading a code, wait for the flashes to stop then hold switch for 8 seconds and release. Then read next code and repeat. You don't need to wait to long after the code finishes flashing or you will have to try it again. After you have gone through all the codes this way and depending on the pin, you should get 1 flash saying that pin is clear. Look around a bit on the forum, but if yours is the 16 pin connector mine has, that way has always worked for me.


To check your wiring harness, cut back a small area of the outer wrapping near the MAF and the one running across your fuel rail. Inside should be nice colorful wires well insulated. If they are old looking, bend the spot you are looking at and make sure they don't crack. The old stuff will possibly fall apart in your fingers, depending on its condition. Mine was bad enough on the ETA that it was mostly corroded copper and dirt inside the outer wrap.

Wire Harness Date

You might also look at the production date of the wiring harness by removing the battery and looking fo a tag on the wire harness in the vicinity of the OVP connection. The production date will be "Fertigungsdatum" (aka the "production" date) FYI - There may be two dates on the harness part number tag - the other date is the design date.

Could be wiring loom. Especially with all those codes and symptoms.

Thank you everyone for your input.

I just checked the date on the wiring harness and it says "03.04.02" so it appears to be a new one . Next step will be to clear the codes and see which ones come back.

In the mean time, any guesses as to what might be the problem?
