#138 of 218 1999 C230 Acceleration Problem / Bogs Down
Jun 17, 2011 (7:07 pm)
I took a risk, and just purchased the above mentioned car, knowing it has acceleration problems. It has a rebuilt transmission, as of 20K miles When pressing on the gas, it bogs out, when you let off the gas and press again, it comes back and continues to accelerate. The seller tells me he thinks its the throttle actuator.... Any other thoughts?

Not really sure about the throttle actuator, but you also may want to check your Mass Air Flow Sensor. If thats what it is, you can find them on Ebay for around $140.00 take 5 mins. to put in. If you get it from a Mercedes dealer they will charge you around $575.00 just for the part.

thanks for that. after hours of searching, i get the feeling this may be the problem. i have seen the replacement sensor for as little as $99. looks like i could DIY. thanks for the info. will post update.

What did you decide to do with your tranny slip issue (limp home mode)?

Does anyone in the Altamonte Springs, Fl area know how to work on a Mercedes C230, and will do so at a fair and reasonable price? Need mass air flow sensor cleaned or replaced.

I want to try cleaning the mass air flow sensor but I am afraid I might mess up. What should I do if something goes wrong and I can't get it back on. Would it cost me a lot to find someone who can do it?

Shay, Buy and replace it your self. it takes less then 5 minutes to do. It is right up front just a little right of the left front headlight. (That is if you have a 1999 C230). The first time I got taken for $750.00 from the Mercedes Dealer. The second time they told me it was the MAF I went on to Ebay bought a brand new BOSCH mass air flow for $140.00 and replaced in no time. All it take is a screw driver to loosen the metal band around the hose, then unplug the wire going into the MAF unit and pull it off. Hope this helps

Air Mass Flow Sensor Cleaner is safe to use for all MAF sensors. Increase horsepower, IMPROVE AIR/FUEL RATIO (this is your case), without damaging the plastic housing or hotwires in the MAF sensor. Follow instructions on the can and you gonna be OK. If you decide to replace for new one it is DIY job.
AIR MASS METER - removal:
Air mass meter is located on the rear of the air cleaner cover on the right hand side of the engine compartment. Unplug the electrical wiring from the sensor by turning the union nut anti-clockwise until it is felt to disengage and then separating the two halves of the connector. Slacken the hose clip at the engine side of the sensor, then pull off the inlet ducting. Release the spring clips at the air cleaner side of the sensor and remove the sensor. Recover the O-ring seal. Refitting is a reversal of removal.
Time to do the job is about 10 minutes or less.
