#173 of 218 Hard shift cluck 2rd gear sometimes. Shift gear valve assembly fault.
Feb 29, 2012 (7:03 pm)
97 C230. 140K miles. Cluck shift sound sometimes, when accelerate at up hill incline.
Dealer said: rough shift only on 3 to 2 downshift. Found transmission fluid dark. Do not understand this -> "performed short test, found stored code for selector lever is implausible, communication with engine module, and reverse/park lock solenoid fault".
Normally would recommend a valve body, but mileage is high. Not confident will fix shift issue without cause clutches to slip. Dealer said : best to replace entire transmission.
But for now, can still drive without much problem.

I have a 2006 C230 Sport that i purchased brand new at the end of 2005 and for about 2 years now periodically when i press on the gas the car barely moves but the RPMS will continue to rise as i accellerate and i try to put it in reverse and it goes nowhere until i put it in park (and it makes a loud thump) and turn the car off and start it right back up and everything is normal. 80,000 on the car and i have changed the transmission fluid and the fuel filter. Mercedes Benz Dealer have not heard of these issues before but i have read similar problems on this Forum. Amazing

#177 of 218 Mercedes Defective 7-Speed Automatic Transmission
Apr 16, 2012 (11:23 am)
Driving my 2006 C230 on I-95 at speed 65 mph, I experienced a sudden loss of power. Fortunately, I got off of the highway safely. My mechanic found that my transmission was slipping together with faulty code 0894. According to the Mercedes service bulletin, "Limp Home Mode," if there is no power transfer and the code 0894 were presented at the same time, then the K-1 clutch is damaged. My car had only 39,500 miles but was out of warranty. I took the car to the dealership because Mercedes promised to help me with the repair cost. The dealer stated the new valave body would solve the problems, so they replaced it. However, it did not make any difference. Finally, they disassembled the transmission and found the blown seal in the K-1 clutch, which was responsible for the clutch failure. They replaced the K-1 clutch along with the new redesigned seal, which indicates that the seal was originally defected. Total repair cost me $4,300 and Mercedes did not give me a penny. Recently, my mechanic tells me there is a shortage of new valve body. According to, http://jayauto.wordpress.com, Mercedes is in a fight with its own suppliers because they produce a low-quality part. If you have problems with your 7-speed transmissions, please report it to: NHTSA. Only this organization can enforce Mercedes to do a transmission recall. In 2011, Mercedes made their biggest profit in their history. However, I don't think they will use it to fix their issues with transmission.

I have a simliar problem. I have a 2007 C 230 sport when I excilarate then come to a complete stop I feel a vibration then when I attempt to excilrate it does'nt want to go even though the RPM has moved. I have to turn the engine off then restart it then I'm fine. I've been told it could be the air conducter or fuel pump. I brought it in to replace the fuel pump which the mechanic indicated the problem to be. However, the problem is still there. He stated that I have two fuel pumps so both were replaced. ????? could you help me if you could thanks.
#179 of 218 2005 Mercedes C230 rolls in Park
May 11, 2012 (11:56 am)
My daughter left me her car in December, when she went overseas. I drive it back and forth to work about 30 miles round trip once or twice a week. About a week ago, I went to the local grocery store and parked the car, placing it in park. When I was getting out, the car began to roll backwards on a really small incline. So, I have to ensure that the parking brake is always on regardless of my location. I was able to drive the car home, as there was no noticeable problems other than the C230 rolling when in park. I drove it to work a couple of times following that. About three nights ago, I saw smoke coming from under the hood when I parked the car at my house. I thought it was rain water that hit the the bottom of the car, as it had been raining and the temperature cooled. Low and behold, it was transmission fluid leaking from some where underneath the car. this afternoon, I put the car on my ramps and intend to go underneath this afternoon to see where the fluid may have leaked from.
For the past 35 years, I've worked on all of my own cars, as well as my friends and relatives. I'm not a mechanic by trade -I am a do it yourself person when it comes to cars. I don't dabble technical issues beyond my capabilities. I have never owned a foreign car, so won't work on my wife's BMW unless its an oil change. I have changed the oil it it (BMW) and on my daughter's C230. I have never heard of a vehicle being placed in park and then rolling on a slight incline. I have also never seen about a quart of transmission fluid leak out from beneath the car like it did the other night. Has anyone ever seen this before or can tell me how a Mercedes goes into park like I've described, and still rolls? I can tell by the 18 pages I just read in this forum, that the C230 is very expensive to repair. Has anyone ever lost a quart of trans fluid? I find it odd, that the car still drives, as I just put it on my ramps.

I found no one who could assure me of a definite fix for the problem so i traded my problems away before it became a money pit even though the 2006 looked brand new with 80,000 miles.
#181 of 218 Merc CE 230 Coupe overheating
May 28, 2012 (2:12 am)
My Merc ce 230 Coupe is overheating. The temperature is reaching 120 in 10 minutes of driving. The Temperature stands still at around 80-90 while driving however when the car slow downs/trafiic signal it increses rapidly.
I stay in Qatar and its summer right now, i think weather plays its role in this problem however the rest of the cars does not get heated to this extend.
If the tempearture reaches 120 i have to either stop on the ROAD or on the road side and wait for it to cool down before driving again.
The mechanics here does not have sound knowledge about why the car is over heating.....
I have to put water every 6 hours to run it...
Your valuable advise or suggestions are highly appreciated with regards to a permanent solution.

Okay...if the car is running all right when you are driving down the road, but overheating when you are in traffic, then you have an AIR circulation problem, not a COOLANT circulation problem. This leads me to suspect that your electric cooling fans are not operating properly.
