I have had this car for about 6 years now, lately it has been starting rough. Once warmed up it runs perfectly fine. I replaced the air & fuel filter, which seemed to help but not totally fix the problem. (there did seem to be a lot of water in the fuel filter.) I cleaned the butterfly on the throttle body and the one to the air filter box. This seemed to have corrected the problem for a short period of time, less than a week. Now it is back to starting up very rough and will not run well until warmed up. I appreciate any and all suggestions.

 

Not sure what that is but mine does the same thing. I know a few people with a C230 of different years and we all have to let it warm up for about 3 minutes or so. The guy I bought it from said that this is just how Mercedes are. This is my first one so I took his word for it. I have gotten used to it so it doesn't bother me.

 

Not sure about it being normal, as the dealer mentioned it as an issue to address the next time I had it in. It only did it for the last 10 months that I had the car... which at this point is kind of a non-issue now. Some guy plowed into me the other night and totaled out the car. I will say, what I did do, cleaning the throttle body, and the butterfly at the air intake, also changing the fuel filter, did help.

 

I am sorry to hear that.. I hope you are ok and they got the guy. Some people need to go back to driving school.
I will try your suggestions. Will you be getting another one? This model must be pretty good. I called every junk yard in Jacksonville yesterday to try to find some speaker covers and a few other simple interior parts and no one had a Mercedes C230 between 97 and 2000.
Again, hope you're ok..

 

MAS air sensor on its way out.

 

What color is your interior, I am about to have a load of interior parts as I will likely not fix the car.

 

It is grey.. That would be cool.. But sucks that it would happen that way..

 

How would I check it to see if that is the problem? There are no engine lights. Would an auto parts store be able to pick it up on a computer?

 

MAS sensors usually don't throw a code until they're shot.I don't know your mileage situation,I would say the life expectancy is between 60-80k miles.If you are having rough idle problems or sluggish acceleration,these are the most common symptoms.

 

Oh it is a bit above that.. 180,000. Besides the few minutes that I have to wait for it to warm up in the morning it drives great. Now that you mention it though the idle does sound a bit off. I just looked it up. Does 300 dollars sound right?

 

Too high ....google "autohaus" in AZ for OEM parts.

 

yeah that is almost half the price.. Thanks..

 

Sorry about the accident. Regardless, how do you know the fuel filter had water in it?
