    Hi melo my name is george,i also have a 2001 c-240 and my warranty is up in 3 wks i know the price is around 2300.00 can. But think if we have a problem later on it will be heavy, think a b-service it costs $500.00,well let me know about it.Thanks

    ...regarding tail lamp bulbs. My 2000 C is due for servicing next month. In nearly five years, I have only had 1 bulb burn out (bottom right tail light on passenger side). I am on my third bulb (less than one year). The light is out for a few moments when the car is started (and the "light out" lamp glows on the dash). After a few miles, the bulb comes on. The outage seems to be random. Perhaps a bad connection?

    definitely take the car in to an authorized MB service center B4 your coverage expires! The worst that can happen is there will be nothing wrong with your car, and you'll get it back clean. If nothing's obviously wrong, tell them you had a sporadic engine light or something so they can look for a code under warranty. That way, if anything IS wrong, fix it while it's still free, and if it isn't covered, take the non-covered repairs to the indie on the cheap, but make sure they know what they're doing. Ask around.

    As far as a B-service, that covers almost everything prior to an actual tune-up at 100k miles, so it's worth it. If your car is on the flex-service system ('98 or newer) it won't need a B-service again until after its next A service, which is less than half the cost of the B. Take good care of these cars, and they'll last you a long, long time.

    The small wrench symbol that counts down miles to service, does anybody know how to reset it, without going to an MB dealer?
  • stroudmanstroudman Posts: 192
    If it was't reset by a mercedes tech, that means you probably haven't taken it to one...BE CAREFUL letting any else around a flex-serve mercedes! You should be able to use the menu buttons on the steering wheel (arrows) to get to the wrench screen. Once there, press the reset button to the left of your instrument cluster and hold it until the #'s reset.

    First of all, thanks so much for all your honest insight and information. I have a question - in the next month or so, I will be trading my Saab 9-5 in for either C240 or C230. In your opinion which is a better car? I split my driving 50-50 city and hwy. I like both cars, but I like the idea of a V6, but I love the looks of the C230 and the idea of more horses. Thanks!
  • stroudmanstroudman Posts: 192
    If you plan to buy new, the 230 is, IMO a better value. But be aware of something - the 230 will cost you less at point of sale, get you much better gas mileage, and be as fun to drive as a 3-series, but much smoother. What you have to take into account is tire wear. "16 all-seasons on the 240, quiet, durable, rotatable. The 230 comes with staggered-width "17, Z-rated tires that you will get a maximum of 15k miles out of. You can replace them with a harder tire, but the cost of ownership will slowly catch up with the 240 over time b/c of the tire issue.

    -Otherwise, one's definatley set up aesthetically to please the lux-minded folks, the other the sporty, youthful crowd, so whichever suits your wants and needs...they have 95% same DNA.

    That makes sense - thanks. BTW, what state are you in?

    Does anyone know what the B service consist of? I have called MB 3 times, and I get 3 different answers. The only thing that is consistent, is it includes and oil change that I can do myself for $50.
    Does anyone know where the fuel filter is and how to get to it; while I have your attention?
    Is getting a Platinum Extended Warrenty (bumper to bumper more or less) worth it ($2500)?

    Don't use anything less than premium. The higher the octane, the more stable and the more it can be compressed . So your car is set up to compress premium to a certain point before it ignites. A lesser octane would cause a premature ignition, before your car is ready for it, causing damage inside the cylinder.

    I use mobil 1 in my c-class because it is recommended by mercedes and is factory fill in
    all AMG vehicles. No problems, I use 10W-30 and it works just fine for most of the year. Then maybe 10W-40 later.
  • ehanekomehanekom Posts: 1
    I wonder if anyone could help me with the reset procedure of the wrench light on C180 1999 model as it does not have the controls on the steering wheel as mentioned with the C230.
  • jcolbyjcolby Posts: 5
    I will own a 1995 C220 tomorrow. Has anyone used an OBD diagnostics tool with this or other Mercedes? Any recommendations on a particular one? The price ranges are from $130 to $1,695. I don't want the most expensive nor do I want to get one that is inadequate. Are any of them adequate for a Mercedes or does Mercedes have numerous codes that can't be diagnosed by a third party diagnostic tool?

    I don't want to be a rocket scientist, just be able to tell, for example, when it's the mass air flow sensor that's causing the "check engine" light (which it is right now, by the way, according to a mechanic). Does something like that require special calibration that has to be done at a shop? :confuse:
  • jcolbyjcolby Posts: 5
    I figured this out by getting a subscription to, which is a good deal. They're the only ones who carry model-specific manuals (on-line) for Mercedes.

    The 1995 Mercedes C220 is OBD-II compliant so I just have to decide on which OBD-II scanner now. They all will read the "generic" codes, I'm trying to find one that will read proprietary Mercedes codes at a reasonable price (max $300). :D

    if you look at the left side of the gauge bezel on your dash instruments, you will see three tiny buttons. Two of them adjust light and dark on the dimmer of your instruments, and the other resets your trip odo. Push it twice to reveal the mileage reading, then hold it down till it resets.

    Being the A-type perfectionist that I am, I am becoming really frustrated by my 2000 C-Class Kompressor's Engine Warning Light coming on due to the "Low Fuel Indicator light" flashing (despite lots of fuel in the tank).

    The Manual says that this is either due to a) me not putting my gas cap on properly (unlikely - see reference to A-type personality) or b) there is a leak in the gas line.

    I have taken it to the MB dealer now 3 times for this issue (2wice under warranty). The first two times they stated that it was just a glitch and they "reset" the system. Then it happens again in a few weeks. The third time they made me replace the gas cap as it was "faulty" at a cost of $125. Still the light intermittently flashes, which then leads to the Engine Light, which I of course cannot reset manually.

    Does anyone else have this problem? I don't have a fuel line leak and my gas cap is ALWAYS on tight. I'm also beginning to wonder if MB knows what they're talking about.


  • jrct9454jrct9454 Posts: 2,363
    I think that the prime suspect is the fuel sending unit, a well-known and common problem with German cars in the last 4-5 years. The supplier [Siemens? Bosch?] seems to have produced the same unit that gets used in several German makes, and they have a habit of failing because [allegedly] of the higher sulfur content in American fuel.

    However, it is precisely because this is such a well-known problem that I have some doubts - surely your dealer has thought about this possibility? If not, put the thought into their collective heads. The most common symptom of the sending unit problem is pretending the tank is empty or nearly so, when in fact it can be completely full - sound familiar?
  • gurekiangurekian Posts: 3
    Thanks for the quick feedback. I'll have to bring it up with them and ask if that might be the issue. The only thing though is that the fuel light does not just light up, but flashes until I turn the car off and restart again. Along with the amber "Check Engine" light it becomes quite the light show when driving at night.

    My understanding is that when the car comes to a stop, engine running, it performs a quick "pressure check" on the fuel line to make sure that there is no leaks, either through the improperly tighted gas cap or through an actual leak in the fuel line. MB has said that they performed a pressure check on the system and found nothing. So is the sensor faulty?

    The car's operation has not suffered at all - just my mental aggravation!

    Can I reset the "Check Engine" light myself?

    My C230K with only 24,000 miles has developed a strange problem.... when cold (meaning "in the morning" no matter how warm it is outside), it just cranks without starting; the second attempt to start makes it run rough at first, then eventually it levels off. After this, drives okay till next morning. No fault has been detected by dealership... any idea what it can be? Many thanks!

    I am curious if anyone can give me any advice on repair costs on Mercedes? I have a 2002 that is off warranty in Feb 2006, and wonder if they "see us coming" so to speak and charge a lot for repairs. I know when the dealership changed the oil, which was part of the Service A visit, on paper it showed $90 in charges. Is that something an owner can do themselves? I am debating about selling the car prior to the warranty expiring, if it will be expensive to work on. Any advice would be most appreciated.
  • jcolbyjcolby Posts: 5
    Has anyone had any experience with this? I just bought a 1995 C220.

    The previous owner was experiencing shutdown while driving. One
    mechanic said there was a Mass Air Flow Sensor diagnostic code and
    several oxygen sensor codes. Another mechanic said there was only a
    Mass Air Flow Sensor diagnostic code. I bought the car and figured
    out what kind of scan tool I needed, etc. Prior to getting the scan
    tool I started the car just to run it a while so it would be easier
    to start later. While idling there was significant vibration which
    seemed to come from the right rear and the engine shut off. Wouldn't
    start again.

    I got the scan tool and when I ran it the Mass Air Flow Sensor
    diagnostic code came up and this came up on the "freeze data": Fuel
    System 1: CLSD.

    I got a new Mass Air Flow Sensor and installed it. I erased the MAF
    code and now everything checks out OK, no codes. When I go through
    the "view data" feature I now get: Fuel System 1: OPEN.

    It still won't start. I put a full charge on the battery to make
    sure that wasn't the problem.

    My question is this: I'm assuming that the fuel pump is programmed
    to shut off if the Mass Air Flow Sensor problem isn't fixed within a
    certain period of time and that this is what happened when I was
    idling. Is that correct? Second part of question: is there something
    I have to do in regard to the fuel pump once the Mass Air Flow
    Sensor problem is taken care of? If no answer I'll probably have to
    tow it in to a mechanic- I don't think I want to mess around with
    measuring fuel pressure, etc.

    A family member is considering an '05 C230 Sedan. This would be the first MB to be added to our "fleet". I'm aware that free maintenance is no longer part of the program. That means the routine maintenance will end up being done by me.

    Have any of you done your own oil changes on your C-class? What type of oil and filter do you use? How many quarts does the 1.8 engine use? Is there an easy way to reset the service reminder after the oil change is done, or will I need a tool similar to BMW? Is there a factory service manual available?

    I've reviewed what the dealer will do and charge for the "A" and "B" services and unless I'm missing something, I'd rather peform the routine service myself.

    Thanks in advance for your feedback! :)
  • jrct9454jrct9454 Posts: 2,363
    You're right about the relative simplicity of the "work" done on most of the services up to 60k miles - with some exceptions, most of it is inspect and report [besides the oil changes].

    No, there is no factory service manual available to the public. There is a relatively expensive subscription service for professionals, and as time passes, a service manual for a particular model is usually available on CD. MB is not making it easy for do-it-yourselfers.

    Join MBCA without delay if your family buys this car. The answers to all your questions are easily available from fellow club members, some of whom are in the service business.

    Oil changes are best accomplished using one of the widely available pump devices [e.g. TopSider] to suck it out from up top. Buy only MB oil filters, no matter what the cost. Use only approved synthetic oils - the list varies from one year to the next, but is in the manuals with a new car - it includes all of the usual suspects, such as MobilOne and Castrol Syntec. MB likes to have a big sump [good!] - our V6 holds 8 quarts - the 4 cyl is 6+, I think, but that's documented in the owner's manual.

    I've rarely indulged in this kind of mechanical work, because I haven't the facilities to do it [condo garage] and because our '02 C240 has prepaid mtc. Also remember that there are things to be done that are time dependent, like the brake fluid every 2 years and the coolant every 3 years, but mostly it is a lot of inspections and top-ups that anyone with good lighting and some mechanical savvy would have no trouble with.

    A final warning - during the warranty period, be prepared to meticulously document all mtc work on the car . If you give them an excuse to void the warranty, this can be a disastrously expensive way to try to save a few bucks. At least for the first four years, I would probably pay to have it done at the dealer - but then I don't think it's as expensive as people think. If you can't set aside $400-500 a year for the first four years [a very liberal figure, by the way], maybe this isn't the right car.

    I appreciate your reply - very good points and although I'm a big MB fan, this is the first time I've heard of MBCA.

    Thanks again!

    Hello all,
    I'm looking to buy a car in near future (4wks). i'd like to hav a sporty coupe. naturally mb c230 and bmw 3-series come to mind. i would like to hav ur opinion on what should i go for (other options definitely welcome). my budget is under $20k so definitely used cars i guess. i would like to know if c230 is worth it and what would b its monthly running costs? i hear c-class has a poor reputation when it comes to reliability and maintenance. also with most of the 2002 kompressor models running outta warranty soon, how would the maintenance charges work out after that?

    also i hear mb is no longer producing c230 coupes? should i go 4 soon 2 b extinct model?

    Thanks in advance.
  • I have a 2005 C230 K Sedan

    I am will do the A & B service myself and keep the records for the maintenance and warranty
    5.8 liters of Mobile 1 0W-40 and NO OTHER oil. available online or from your MB parts, MB Fleece oil Filter and nothing else - not too xpnesive
    Get a Fluid Extractor - about $300.00 to $500.00 available on line suck out the oil through the oil dipstick tube or jack up the car remove the underside plastic panel and drain it like any other car

    Turn on the key but do not start the engine. Select the Service A due display on the dash computer and press the reset button (on left of instrument cluster) for 10-15 sec

    No factory service manual for MBUSA until the warranty has run out - 5 years. Make friends with your registered MB mechanic or dealer parts manager and have him order you one
  • Thanks for your reply. Exactly the info I was looking for.

    New to this board--looking for educated advice. We own one of the last in-line 6 MB's--a 1996 C280--which we enjoy and much prefer over the newer V6s that we have also owned. I've heard that it is entirely possible to use regular gas with this engine without damage or diminished performance. Is this correct information? Must we continue to use premium gas with this engine? Many thanks for your advice.
