    I've had one since September. I bought it with 26,000 miles. Car has run really well. We had an issue with the memory on the sunroof not allowing it to close properly. Phil Smart took care of the issue with an update to the car's computer. Other than that, the car has been great. btw...go with at least a C240, as the 6 cylinders are what you really want.

    The car gets consistently 22.4 mpg comblined between highway and city.

    cool..thanks for the advice..I actually picked it up yesterday. I ended up upgrading to the E320. Both are GREAT cars...

    Yeah. If I didn't have to parallel park downtown, I think I'd have gone E-Class too. Congrats on the new car.

    Just had lots of maintenance done to my 2001 C-240. Has only 76,000 miles:

    1. replaced front/rear engine mounts
    2. replaced engine belt
    3. power steering flush
    4. brake fluid flush
    5. coolant flush
    6. replaced side seals
    7. replaced air mass censor

    Does this seem excessive? Because it cost a fortune & I'm wondering if I should consider getting rid of it.

    I'd appreciate thoughts on this...........thx.

    replacing the mass air flow sensor (MAF) is bull. That should be cleaned every 10k for a couple of bucks. Its two screws to get to it, and you spray it down with a $10 cleaner. There is no way that should have been replaced under normal conditions.

    Everything else is typical car maintenece from what I can tell. The engine belt? Are we talking timing belt (in which case, 76k is early) or an accesory belt, like for your A/C?

    Thx for your input. It was the engine belt due to cracking.

    This if my 1st Benz. Prior to this car, I had a Ford & never had to do any of this stuff however, I sold it @ 7 yrs. I was planning to keep this car for 100,000 or plus miles.

    Just seemed like a lot of items needed attention all at once.

    I'm in the middle of rebuilding a mercedes 123 diesel. There are no oil jets in this one as described in the book. Looking further I have found no oil passage in the conrods. The engine was recently rebuilt and the conrod numbers don't match up with the corresponding cylinders, so they might have been replaced.
    My question is how does the oil cooled piston get the lubrication it needs if there is no way for the oil to get to it?
    I,ve posted in other forums to try to get this question answered and am hoping there is some mechanical genius out there that can help me out with this one.

    Any and all help would be greatly appreciated.
    Thanks,

    Hi - welcome to CarSpace!

    Let me recommend that you also post in our Technical Questions discussion. You might be more likely to find that mechanical genius :) there, but we'll see if one shows up here as well.

    Good luck - hope we can help!

    I just bought a motor home and want to tow my 2002 C-240 behind it. Does anyone know if you can do this without causing any damage to the transmission/drive train?

    I recently had the C240 at the mechanic to replace rims and align the car and he said the spark plugs need replaced. the engine runs very choppy at idle and also making a whining noise when i start it up in the morning, until the engine gets warm. how hard is it to change the spark plugs and where would i find out how to do it myself? secondly, does anyone know what the whining noise is? It never happens unless it is cold outside. thanks for the help.

    I belive the noise you hear is the electric air pump for emmissions. It will run for 5 minutes or so and then shut off. The spark plugs are pretty easy to service. Simply remove the air tube across the top of the engine, remove the top cover that sets ontop of the valve cover, by taking loose the 8 allen head bolts that go through the cover then you`ll see the coil packs. they can be removed by taking loose the 10 mm bolts and setting aside to uncover the spark plugs that are down in the head tubes.

    I don't know about 2003 model, but I guess things don't change much, especially for Mercedez. I have a C 240 2001 model and feel so regret. I drove BMW and wanted to try out Mercedez. This was a big mistake. This car has so many problems, ranging from small electrical light sockets to big items like transmission oil crack, accelerator sensors, etc. I've been spending in average about $1000 to $2000 every 2 months or so to keep the car running even though we always have regular services with Mercedez Benz. Every time we bring the car in and out, it's always > $1000 service. We're always in the upset mood w/ this car because things are broken every 2-3 weeks or so. Think twice before buying any Mercedez Benz, just 2 cents.

    I have the same car C240 MB, 2001. It's a piece of junk. I've had so many problems with this car that I want to get rid of it today. We've been spending $1000 to $2000 every 2 or 3 months to keep this car running even though we have regular services w/ MB dealer. Electrical things including expensive sensors are failing everywhere, transmission oil cracks, engines die at middle of intersections, etc. Every time I bring the car to the service, it costs $1000 to $2000 easily. Big mistake. Never MB again...

    I have a 2003 C240 Wagon 4Matic with 59k miles and no major problems. The door actuator went out on the drivers door and one of the tail lights burned out....thats it. I have read that they ironed out a lot of the problems during the first two years of production....or at least I hope they did. The car drives very nice and almost feels like our 1995 E320 Wagon. A little more power would be nice but it is just a wagon.

    Can someone provide comments and experience on my recent situation with my C240 4-Matic Mercedes Benz (2005 year).

    When car is cold (I live in the Northeast), there is loud brake scrunching noise when I step on the brake.

    Also, is it normal for the sterring wheel to be tight at slow speeds? It requires "extra effort" to turn. I also have a Toyota and steering wheel is never that tight as my Benz.

    Thx in advance. Ed

    While not 'Benz' specific, the crunching noise, if it goes away after one or two brake applications, could be just a small bit of rust that formed on the brake disc. My Jeep will do that, especially if I park it after driving in the rain, and not drive it again for a couple days.
    As far as the steering goes, it would make sense that if the fluid is really cold, it may take a little extra steering effort until the fluid warms up. I would think it would have to be real cold though. Here in seattle, it doesn't get that cold, so I haven't really experienced the problem you have. Hope this helps a little. I'm sure some other MB folks will chime in.

    I obviously have a leak somewhere because I keep vacuuming out the area behind my passenger seat. We're due for a lot of rain, so if someone has a suggestions on how/where to check and see if I have a clog or leak, that would be great!

    Folks,
    I am considering buying a 2004 MB C240 4Matic with 43,000 miles on it.

    What, if any, negative experiences have people had with this model?

    What is the most frequent repair issue that has come up with this car?

    All responses appreciated!

    Thanks.

Not only the bottom part of theseat but all the way up the back and into the ceiling header. Mercedes Benz has had the car for 5 days and can't figure out what is going on! Help!! :mad:

    Hello all !
    New here...figured it would be an intelligent place...
    Wife looking to buy a used (2004) AWD Sedan. Each has about 68,000 miles on it.
    Prices are apparent differences, will deal with that later.

    Looking at:

    Mercedes c-240
    AUDI A4 1.8 Quattro
    Infinity G35x
    BMW 325xi


    Not looking for a 'race car'. Standard wife car; comfortable; good in snow. She likes these styles, so the Subarus are not a consideration.

    Looking for opinions on each.
    Maybe a quick summary that you may have on each.
    Seeing that it is an Mercedes forum - please feel free to let me know why I should get her the Mercedes rather than the others.

    I look forward to all your help.
    Please be as lively and opinionated as you'd like to be !

    Thank you !!!

    Tooky

    (Will post in the other forums also)

    How much does it cost usually where you service your C240 car for B service?

    I have a 2002 CL. I bought it used with 17,000 miles. It currently has 54,000 miles.

    The transmission fluid is cooled by the radiator. This past Monday (10/18/10) the transmission burnt out. The Mecedez dealer stated I need a new radiator, transmission and gear box, ($7,100.00). I'm looking to see if there has been any class action lawsuits filed for this design error.

    I've been on line and have discovered the standard radiator "Valeo" will break down and allow glycol to mix with the transmission fluid.

    I believe Mercedez should be liable for the correct repair for this car.

    I have read numerous accounts concerning the faulty Valeo radiator that seeps an insidious contaminant, glycol, into the transmission of the 2002-2003 built C class. My 2003 C240 has had numerous problems with this. At 44,000 miles MB put in a new transmission but did not replace the radiator!! Fortunately it was under the extended warranty at the time.
    Now 30,000 miles later at 78,000 miles I had a glycol test performed and I had "LOTS" of glycol in my transmission. Unfortunately now my car is out of warranty!!
    MB dealership finally changed the radiator, torque converter and flushed the system..and the service advisor said "I would fix it and sell it"!!
    I was hoping to drive this car for another 10 years..it is in excellent shape!! However there is no guarantee that other parts of my tranny will give out!
    I've seen many posts concerning this issue and to my knowledge no class action suit has been pursued! If anyone has any information to the contrary, please let me know. I feel a class action suit should be filed because us consumers are getting a very raw deal!!
