#153 of 220 2003 Mercedes Benz C230 - Oxigen sensors issue
Sep 15, 2011 (4:34 pm)
My 2003 Mercedes Benz C230 Kompressor has 54K miles and I just bought it in May and my mistake was putting PLUS Gasoline istead of the PREMIUM and the front Oxigen Sensor went bad. But the car wasn't turnig on normally, I was having issues making it run. When I turn ON the key it just started if I press on the gas pedal. So my question would be if the oxigen sensor would be a problem so the ignitions won't turn on normally?

No, it's just a co-incidence if your 02 sensor failed at the same time you used PLUS gasoline. Your car's computer can adjust for whatever type of gasoline you put in it. All you'll notice is some loss of performance but you can't hurt anything.
As for hard starting with a bad 02 sensor, the only thing I can think of is that a bad 02 sensor may cause the car to run rich or lean, and that might have fouled the spark plugs.
#155 of 220 1998 C230 Seat Controls and Climate Control do not function properly
Sep 15, 2011 (8:29 pm)
I have a 1998 Mercedes C230; have had it for three years. It's a wonderful car, but currently has a couple of major drawbacks; the seat controls started intermittently not working... then they started only working in hot weather... now they don't work at all.
The other side of this is the climate control. When I set to a temperature, or just crank the fan up to full-blast, I can hear the fan working overtime within the console, but little-to-no air comes out of the vents. This makes it difficult in both the dead of summer, and the depths of winter (or vice versa).
On both counts, I've had a Mercedes dealership and my local (and trusted) mechanic look into it. They've said it's a problem with the computer in the central console (the dealership called it a... "convenience" module, or somesuch?).
I'm primarily trying to find out the name of this part so that I can find a replacement on my own. Can anyone point me in the right direction for this? Or give me any other suggestions?
Any help is appreciated; I don't look forward to another winter having to hold a snow-brush out of my driver's-side window to keep the windshield clear.

Did you find out what was wrong.
#159 of 220 CA Smog Issue
Oct 28, 2011 (6:50 pm)
Wife's 2005 C230 Kompressor with less than 50K on it. Mechanics reset and say drive for 200 miles then take to smog. Without fail light comes back on and no smog..again!
Dealership has 'given up' even they dont know what to do. Last suggestion they're going to drain all the gas in the fuel system and put in Chevron with Techron to see if that makes a difference.
Any suggestions, dont have the error codes to hand.

my Check engine light is on solid yellow. Last Thursday12/1 I put gas in my car(premium). Friday 12/2 my light came on. In Oct I had a service B done to my car no problems. Sunday 12/4 I went to autozone to get a diagnostic. they came back with 1. thermostat defective or 2. sensor defective or 3. coolant level is low. I checked coolant level that's ok. I'm hoping the joker at the gas station put the right gas in my car. I was not paying attention. Now i have read blogs saying to replace sensor/ thermostat could run me $200-800. should i wait and run the gas down to see if that was it or what? any answers?

Well, as surprising as it sounds, these trouble codes don't actually tell you what's wrong--they indicate where to start looking, but your car's computer cannot single out defective components--it only indicates systems or circuits that might be under distress. I'm not even sure that the codes were read correctly, but if they were, it might make sense that a bad sensor could light up an engine light. The only way bad gas could cause this is when it causes a misfire, and misfire codes are generally easy to read.
You might also check your gas cap and tighten it up.
There's also a different way to check coolant when hot or when cold. Be sure you are reading the correct level in the overflow tank, depending on a cold or warm engine.
