    Could be a quirky relay but one would need a wiring/relay diagram to see if one relay box controls all these items. If it does, that would be a likely suspect; otherwise, such bizarre behavior suggests a fault in the wiring harness or perhaps at the fuse box wiring. These things can be tough to track down. But try to sniff out the relay issue and also make SURE your battery connections are clean and that your battery/alternator is operating at proper voltages. Any drop in voltages will cause your electric systems to go bananas.

  • Hello everyone, I have a 05 C-230 Kompressor and i would like to know where's the location of the transmission fluid tray and the stick to check the fluids. I recently change my oil and oil filter but i'm having trouble finding the transmission fluid tray and stick. If you guys have the knowledge and pics of the locations it will help me out a lot.

    Thanks
  • I have heard from all MB mechanics that an owner SHOULD NOT change their own transmission oil. It is hygroscopic and water will be absorbed... just like brake fluid Changing oil is one thing but transmission and brake fluid are dangerous to change!

    In fact real mechanical technicians use a suction device to remove all the transmission oil before changing. They are that careful to avoid entry of moisture.

    You shouldn't even consider adding even a little bit of brake fluid from a can that has been opened! I learned that on the first Porsche I owned back in 1965 :shades:
  • I have a 2005 Mercedes C230 Kompressor that has been perfect for the 4 years I had it. However, today the message came up "Taillight Lamp Left". So I proceeded to replace the bulb which had burned out. I took it to the dealer and he put the new bulb back in the board and I drove off. As i was leaving the message still appeared; "Taillight Lamp Left" along with "Taillight Left Lamp: Backup light on".

    We tried replacing the board that holds the bulbs and that wasn't it? The message still appears. Any thoughts?
  • check the harness under the middle console. I had the same problem. a loose wire was the cause. strange thing is I disconnected the battery and it happened again.
  • c230 kompressor failed inspection, seems the air flow sensor might be a problem. check engine light keeps coming on after the computer is cleared it works for a while then comes back on. I replace it from a shop on amazon $100 bucks the machanic is scratching his head... have no idea what to do. help

    2003, C230C coupe. 61,000miles. Battery error every morning for the last 2 weeks. I got new batt. Used a power mantiner that you plug into the lighter so I would not loose voltage while I removed the old batt and installed new. Everything went great. Didn't loose any radio settings, seats or anything else. The only Malfunction is the message "SRS system error go to workshop". The red SRS light is also on. Car drives fine. How can I reset the error and see if it comes back. I have turned the car on and off 4-5 times but message still shows. I do not want to pay MB $120 minimum for them to push a reset button.

    Let me know what you think.

    I think you need to go to a dealer or repair shop and hook it up to the STAR system or some such. This only takes 2-5 minutes. They should do it for free as a courtesy.

  • We have a 2002 C230 with 120,000 miles. I have some electrical problems and not sure if they are related. The big one is we have no low beam, parking light or turn signal on the drivers side. The cable coming into the cluster has 4 functions,, including the high beam which works. I swapped all of the bulbs to the passenger side and they all work. I checked the fuse and it is good. I swapped it out with the passenger side and it is fine. I also checked the fuse box and there is power to the fuse. There is no power to the cluster. Am I missing a connector somewhere? Also the battery goes dead if the car is not driven everyday. We put in a new battery but didn't help. I don't know if this is related. Also have a bad noise through the radio so right now we pulled the fuse for the sound system. Any help here would be great.

    Well congratulations on attempting a logical and diligent diagnosis, first off.

    Yeah you know this all does sound related and I'm here thinking....what component could cause all of this to happen?

    I came up with two ideas, one vague, one more concrete.

    Vague: A glitch in the wiring harness from the headlight to a connector or junction box further up on the firewall.

    Concrete: Your headlight switch itself or the connector that plugs into it.

  • I ordered a service manual that has a wiring diagram. I am thinking it is something little. The headlights went out and came back on a couple of times before going out completely. It seemed like a connector falling off but not sure where to start looking. I can see if I can located the switch and see if there is a connector off. Wish I had the diagram now.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,043
    You might try turning the headlights on and with someone watching start jiggling wires.

  • I'll give it a try. Thanks for the help
  • For the past 5 months, I have a repetitive Check-Engine light from what seems to be a pressure surge in the fuel tank. I get an emissions code, usually gas cap not sealed AND liquid gas on the cap gasket. The tank pumps have been checked and the vacuum valves tested OK. The pump pressure sensors have been replaced and other connections checked. The problem just occurred again. Has anyone heard of a similar problem and what to inspect, test ,etc. The repair shop seems unable to solve this problem!?!
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,043
    Do you remember the number of the trouble code?

    MODERATOR --Need help with anything? Click on my name!

    If the emission code is PO455 Evaporative emission control system leak you need to monitor the fuel tank pressure on a cold engine start during the evaporative test.
    The computer is measuring a vapor leak or it "thinks" there is a leak because the pressure does not change AS IT SHOULD.
    To test the car by yourself, do the following:
    1. clear Check Engine light.
    2. fill up your tank TO THE TOP and make sure gas cap is sealed well.
    Run the car until you spend 1/2 of the tank. IF the Check Engine do not reappear, you have fake call from your computer.
    Hopefully, first or second test will help you out.
  • My wife's C230 is experiencing problems with the alarm going off periodically for no apparent reason. Sometimes the lights just flash and at times it will sound the alarm. Can anyone give me a clue as to why this happens?
  • I HAVE A 2002 C320 AND IT WOULD NOT START AFTER IT SAT OVER.NEW BATTERY AFTER A COUPLE OF DAYS SAME THINE.COME TO FIND OUT IT WAS THE POWER SEAT CONTROL BOX UNDER THE LEFT AND RIGHT SEATS.I UNPLUGED BOTH AND IT STARTS EVERY TIME.THAT BOX GOES FOR 900.00 AT THE DELEAR

    I have the similiar issues as SailrPete. My 98 C280 has the cehck engine light on. Dealer fixed wiring, oxegeon sensor, engine rcomputer and valve connect to air pump. All of these fxies are not working. It is still on after about 30 miles of driving (after code cleared). I like to try your advice but don;t know how to clear check engine light. Please let me know how to do it. Should I put a new gas cap. It's still the original one since 1998?
  • kufukufu Posts: 14
    To clear check engine light you need diagnostic tool OBD II auto scanner. You can buy it at AutoZone or over Internet. I use "Actron" model CP9175 for my '98 C230.
    Next thing to do is put new gas cap. It MUST be OEM and only dealer sell it.
    Third, clean up entire fuel system with cleaner recommended from the store.
    Next time when the engine check light is on for any reason, go to the any benz forum and try to get right answer for the problem. Check engine light does not afect performance of the car. Last thing is to see a dealer.

    I have a 2005 C230, message came on for brake to be serviced or changed. Should I use my expensive dealer or can I go to a certified foreign shop. Car is still under warranty. Cutting back on expenses, so I am just wondering if this has any effect on warranty. It is a supercharged 4

    My 2006 would not change into gears. c\s switch would not work. any ideas.
  • Recently received a 2006 Mercedes c230 into our shop. We retrieved a p2188 & p2190 codes. The codes are listed as rich condition at idle at start up, bank 1 and bank 2. The customer says that when he first starts the car, the idle goes up and down a few times, then smooths out. Has anybody come across this and has fixed the problem?

    Two years ago I had problems with my Mass Air Flow Sensor and replaced it. It is going bad again. I had no major problems before this.Is there something that could be causing it to go bad so soon? I supposedly purchased a new one. It seems as though everything on my car has gone crazy. There is no air coming out of my floor vents, all air seems to be coming from the windshield vent. Airconditioner does not cool, windshield wiper does not work and the cooling fan is on constantly. If they were all related I would be so happy and could this be possible?
  • The spring mechanism that holds the rear trunk cover up when opened doesn't work and the trunk will slam shut if not held open. I have been trying to find the name of the part(s) responsible for this. Could it be a bad hinge?

    The ignition switch will not turn after fixing squeaky noise on driver side seat.
    I should disconnecting battery cable prior to unplugging electrical wires.
    I think that it has open circuit in feedback system had to reset.
    Anybody had a similar experience on this matter?
  • corbex23corbex23 Posts: 1
    hey jape well I can tell you one thing my car is in the shop for the same reason right now and they told me its my valve body on the transmission is bad and the news only gets worse it costs me 2100$ to repair its suck I know but have that looked quickly because the problem may only get worse and more expensive!
  • phycmcphycmc Posts: 1
    I have a '00 C230K. The air flow is working intermittently - usually on starting the car the air will not flow independent of the position of the fan-speed dial. Usually after a few minutes of driving the fan comes back on, but it does not always remain on. Is the cause likely a loose connection? Is there a simple way I could diagnose?
