Sometime when I used the automatic, it would run about a minute or two then stop.
Mercedes Benz has changed air conditioner relay and air conditioner blower it still doing the same thing.
I need to know if anyone of you has ever experience a problem like that C240 03.
thanks
Control arm bushings may not be urgent, but they could eat up tires if they were really bad.
Thanks

I have a C230 yr 2000 and my directions are listed on page 84
here is the directions for 2000 C230,since yours is two yrs newer than mine it may not help you but it may help someone with same yr as mine:
1. turn electronic key in steering lock to position 2
2. within 4 seconds press button "0" twice. "located on dash just below +,- buttons"
3. the present status for days or distance is displayed.
within 10 sec turn electronic key in steering lock to position 0.
4. Press and hold button "0" while turning electronic key in steering lock to position 2 again. The present status for days or distance is displayed once more.
Cont. holding button "0".
after approx 10 sec a signal sounds, and the display shows 10,000 miles for approx 10 sec.
FSS now is reset.
It took me a couple of trys to get it to work and reset my FSS.
Thanks
My 2003 c230 coupe is scheduled for another B-svc. I'm no longer under warranty so I'm considering going elsewhere instead of the dealer to get it serivced. What does a b-service consist of and do I need to get everthing done or can I just get an oil change? Thank you so much!
My '08 GL with Macadamia MB-tex interior is experiencing severe discoloration on the seating surfaces. A friend who had the same interior on an '07 experienced the same problem, although I incorrectly assumed it was unique to his. Now another friend with an '08 model is having the same problem I am. In all cases, complaints to our dealers were met first with denial that there's any problem, then advice to use a dry cleaner strength solvent (which apparently is now difficult to obtain).
My dealer told me the problem is blue jeans. The rubbery nature of the seating surface apparently picks up the dye in the jeans, darkening the material. It's only taken 3 weeks for mine to look awful. This isn't from new, unwashed jeans either. Just my and my wife's regular duds that have been through the wash plenty of times.
I'm interested in hearing if any other owners are experiencing this problem. I think it should be considered a defect and a remedy should be provided at Mercedes' expense.
The only thing major I had over the 8 yrs to have fixed on my car was a feul gauge sensor $400, I did learn at my recent oil change at the MB center that the front flex disk has some play in it and I will have to have that replaced within the yr ($370) but overall no problems here with my 2000 c230 kompressor MB and it has 130,000 miles on it.
I agree with one of the previous posts, every brand of car will have some cars that are made that have problems but not all.
Anyway, from reading up on this car, it seems there are lot of problems with this line. They also seem very expensive to maintain. How reliable are these vehicles?
Are folks compromising just to have that Mercedes name?
Did the dealer offer this to you when you purchased your vehicle?
Thanks
Or....the sensor is out of whack...
Merc 2002 C320
Caused by failure of Convenience Feature (CF) Relay K24
This relay is located in the trunk under a plastic cover between the spare wheel and the seatbacks. To access it, remove the carpeted cover over the spare wheel and then remove the black plastic cover held by three large flat screw-on nuts. The relay lays horizontal on the right side. It has two very large wires attached (red and pink). It unplugs from the harness, but the clips holding it in will have to be pried away from the relay.
The Mercedes Part Number is molded into the cover. It probably isn't as expensive as some of the other MB relays, but unless it has been redesigned, it will just fail again in a few years or less. I suggest repairing it or asking an electronic tech friend to help.
If you are capable of soldering PC boards, the relay can be repaired easily. Using two small round-blade knives, pry off the relay cover. Examine the PC Board near the plug-in base at the center. The solder connection from Terminal 2 to the N/O contact becomes de-soldered at the relay due to high current heating the etch. I suggest scraping off all the green solder-resist between the relay contact pad and the plug-in pad (only about 1/8") and flow solder over the whole area between the two points. That helps dissipate the heat. Usually that is the only solder connection that is bad, and the relay can be re-assembled.
Restarting the engine will often make the light go out for awhile, but in the end, it will drive you nuts. You really need to get to a dealer to fix this problem - there are no "home solutions".
Then MB tech replaced a wiper sensor and a relay switch. Works fine now.
Its a 2002 C230 (C-Coupe...important to note for item #2)
#1 is that in (yellow) turn signal lights that are in the passenger's side mirror, I have two bulbs out (middle two)...assumption is that they're simply burned out and need replacement.
Q: How the heck do I gain access to them to change out these bulbs? It looks like I can pull the mirror rearward (against its spring), rotating it around 90 degrees, but doing so doesn't seem to provide obvious access for service: is the next step to somehow disconnect the tension spring (and not lose it) to then unscrew the hinge mount to disconnect the entire mirror assembly* from the car...?
(* - except for the wiring harness)
#2 seems like a bad electrical ground problem. The radio plays fine (no static) under normal conditions, but if I hit the rear window defogger switch, I get a strong static over the radio.
Defog seems to still work fine (mirrors & rear window). Dealership took a look at it around a year ago and said something to the effect that the suspecte culpret was the wires in the hatchback's rear window glass and to fork over $1000 please. An independent garage suggested that it might instead be the radio antenna's amplifier, which is hidden somewhere in back, but he didn't mention where (headliner?).
Q: opinons or assessment of the validity of these 'troubleshootings'? And if its simply a bad electrical connection, if I can track it down & do it myself. To that end, where to go look for bad connections?
Q2: In bending back the outside mirror for #1, I realized that the static could be from a bad ground anywhere in the defog loop, which includes both of the outside mirrors. Inside the mirror assembly, I noticed two wires connected to the top of the glass mirror, but they look suspiciously tiny for a heating circuit...IIRC, it was two very thin gage wires that were connected to the top edge of the mirror glass - - are these more likely to be for the auto-dimming circuitry and I need to keep looking further to find the ones for the defog circuit?
-hh
Answer 2: How often do you use the rear defroster? If not a lot, I would just live with it or listen to a cd when it is cold out... Although, it does sound like a wire touching. Pull off the dash face plate and have a look around.
I thought I saw a lip on the clear plastic there; will take a peek. Any idea on the model year break-point for when they went to this configuraiton?

I'm in Northern NJ, so needing to use the defog is a pretty frequent in colder winter months, and during a snow event when you get stuck in stop-n-go traffic, the lack of a rear wiper makes using the rear defroster a near-constant requirement for the whole trip home.
I hadn't thought about checking out the radio-in-dash end of things, as it plays fine under all conditions the rest of the time (no interferance from windshield wipers, etc), but I'll add it to the checklist to be thorough.
-hh
I did find something else quite odd in that it looks like my back seats won't properly flip down ... seems to have a new (third) plastic clip thing between the hinges under the knees that's in the wrong position or something. Have to wonder just what the shop did to the car the last time it was in (I had them searching for a possible loose ground on the radio antenna amplifier).
-hh
Thanks for your advice. By looking at other sites including the one you recommended, I was able to develop a list of possible culprits for the gas smell that included the fuel pump housing (turned out OK), a leaky fuel injector (Thankfully, not a problem. That is a very expensive repair), and bad fuel rail seals (Close, but not quite it). The problem turned out to be a worn out fuel pressure regulator that leaked fumes due to deterioration in the unit brought on by cold weather.
Apparently, this is a growing problem in W203 engines and older C-Class models (1997-01) according to the mechanic, so W203 and earlier C-Class owners, beware. Repair costs are reasonable for this problem on a W203--about $135. Parts costs for other MB engine types might be higher depending on engine type and age.
oil service every 10k miles - cost $180 - $300
new brake rotors every 20 - 24K miles - cost $1050
new tires every 20 - 24K miles - cost $800
Is this normal? :confuse:
New brake rotors every 24k is not right. I did 55k on my wifes 240 until I changed them. Dealer was charging about 800. I did it myself. took about 2 hours.
New tires every 20k??? No way. I have 55k on my original tires. New tires for this car are about 450-550. You dont have to buy them from a dealer. Go to a tire store. I going to buy some very soon. These still have an ok amount of tread left.
Looks like this car doen's have a crankcase cap to drain the oil, and I need a oil pump or vaccum to drain the oil out. It's that true? or someone knows if this engine has a crankcase cap and where is it located.
Don't forget the right size socket for removal of the oil canister cap. I believe it's 27MM.
My mother's c230 does this consistently, in various pitches, anytime the fan is on for the climate control. terren272@yahoo.com THANKS
