Hello All,
We had the "Check Engine" light come on last month on our 96' C280 with 79k on it. We took it in to a Mercedes independent in our area and had it looked at. Well it turned out to be an Oxygen Sensor, the mechanic showed us the junction between the wiring and the sensor body and there appeared to be a tear between the protective layer of material, so we had it replaced. He also had his exhaust measuring equipment hooked up and operating. The problem is, about 20 miles after the replacement, after shutting down the engine, you get a strong sulfer-ish smell from the exhaust pipe. Not sure if this is related, but the gas mileage has never seemed great in this car with mostly highway cruising(haven't calculated mileage yet, as the car is not driven often). Anybody have any suggestions and thoughts? Ross ------------------ 96 C280 |

It's normal. Look it up in the archive for
a tech answer. Mine does it and other posts indicate it as normal. p.s. Benzmac recommends to keep an eye on the wiring harness at the thermostat. A general point of problems for these cars. cheers. ------------------ 1979 300D 133K miles 1989 300SE 1995 C280 |

If the O2 sensor did fail, it will take a while for the adaptation to calibrate the fuel mixture again...The shop should have reset this after making repairs, but if not, it will reset after a while.

Thanks Donnie,
The weekend is coming up fast, guess its time for a long nice drive to the coast to put some miles away. If any C280 owners are out thier with high mileage numbers, I would be intersted in seeing some numbers? I saw a 98' last week(I think, had the sport body kit) and the car already had a grill badge awarded? Thanks, Ross ------------------ 96 C280 |
