I need the chip with the upgraded software for the ECM-HFM. After through investigation, this is my diagnosis. Air/fuel mixture is too rich. This will takecare of the Check Engine Light and code 19.

I installed 205/60 tires and the spare is the original 195/65. What effect will it have on the diff if I install the spare tire?

I recently bought my 94 E320 with 58000 miles. I was disappointed by the engineering on this vehicle. Technology is form the 80’s, especially the electrical and engine cooling systems. I would not have paid $43000.00 for it in 94 but at $10500.00, it is not too bad. Ride is solid, fit finish and quality of materials is better than my Pontiac Montana. My previous car, a 2000 Nissan Maxima was one of the most reliable cars in the world, but the ride was jittery.

Engine Gasket, Both Aux fans and EGR valve were replace by the Mercedes Benz dealer before I bought the car. I replaced the Engine Wiring Harness and dealer is checking with the factory rep to get me a refund.

I have installed an Alpine MP3 CD changer, and as soon as I can upgrade the ECM, replace the Aspirator motor for the climate control sensor, change the Aux fan fuse from 15 to 25 A, my car will be in near perfect condition, well as good as Mercedes designed it!!!

I was surprised to learn that a little rattle form the drivers door was a fairly common occurrence in this model. I had always heard that Mercedes Benzes were built like a tank, rock solid and quiet, but I can hear various fans coming on and off, the AC is not very quite either. Transmission shifts are firm, GM transmission are smoother, but I drove it on a 630 mile and it was very comfortable.

Has anyone tried to install a five speed automatic in the W124? It sure could use a fifth gear. I was surprised to find that it did not have a lockup torque converter either.

But to summarize, I still like this car better than all my previous vehicles (Buick Century, Ford Taurus, Ford Probe, Mitsubishi Galant, Pontiac Montana, VW Passat and Nissan Maxima).
