95 C280

Problem:
Car would start and run just fine, until I would slow down to almost a complete stop then accelerate hard (like when making a right hand turn onto a busy street), then it would stutter, and sometimes even backfire, engine would then run very rough under load and at idle. Turn off engine and restart and problem was corrected.

Problem Cause:
Faulty Ignition Coils.

Solution/Description:
Check Engine light did NOT come on with this problem. MB Shop was not able to find problem. Dealership was not able to recreate or find the problem. Finally after 3 months and several trips to the shop, the car would no longer start. It would crank and crank but get no spark. At that point, the dealership FINALLY detected that 2 of my coils were shot.

The c280 has the inline 6 so there are 3 ignition coils, I replaced all 3 for a cost of around $800. Car works perfectly.

Had exact same problem. Replaced one bad ignition coil, rubber ends on all three ignition coils, and all three spark plug wires. Car runs better than ever!
Ignition Coil: $86.00 (wholesale from dealer)
Rubber Coil Ends & spark plug wire set: $55.00 (Bosch from Autohausaz.com)

Thanks for the solution!

Wow after reading this forum I must say I feel very pleased and lucky with my 1995 C220 Esprit (called SE in Canada) - considering I picked the car up from local public auction at very little money.

it's got 213xxxkm on the clock and it's ticking strong. the only issue with it is that the cruise control is termpermental (works like 10% of the time) and high beam flasher only works when the stalk is pushed forward (i.e. no passing flashes, but regular high beam is ok)

From the way things look I think I got myself into a very deep money pit..... Currently it's at Mercedes getting its SRS light reset (I snapped the coil connector behind the steering wheel by mistake and replaced it with a new part, SRS light is on ever since) they might charge me a lot of money to repair it - oh me so doomed.

anyway paranoia aside here is my finding:

Problem: Car randomly stalls when stopped at the light. with one or more of the following:

- engine check light does not light up when in "test" phase - key in position II ignition off
- ABS light on
- speedometer points at 0 and odometer does not advance
- idle speed randomly drops below 500rpm but if you are alert and you put your right foot down the idle will come back up

Problem cause: faulty OVP causing ECU to be unable to read in MAF sensor readings

Fix: replace with a later model German made OVP. Austrian units are known to fail.

Problem: rough shifts (up and down shifts) in all gears
Problem cause: transmission vaccuum module might be faulty. In my case the PVC straw (<- yes straw) that M-B put in the car simply disconnected from the vaccuum module

solution: check for leaks in the vac system (in my case shove the straw back into the vaccuum tube at the transmission) or a new modulator is required.

I had the same problem with intermittent seats. I replaced the relay in the trunk and it fixed the problem.

Make sure the vehicle is off and no keys in the ignition, and you can carefully pry the plug off the relay. Just be careful not to break it. Replace it at your dealer, about $30.

Should fix it.

 

[n0alpha]

I read here that it is the relay in the trunk under the plastic cover, I tried to take it out and it is very hard. Does anyone know how to pull it out. And how much for the new one.

The part number is: 0015420219 (this also can be used to replace older part 0015424419)
And it's just a generic relay used for many different functions on the car. Costs about $29 at the stealership or $14 at www.autohausaz.com

2002 C230 Kompressor

-----------------------------
PROBLEM: Certain gas pumps will not fill the tank.

CAUSE: Unsure of cause. Possibly back pressure or something.

SOLUTION: Try another gas station, drive the car some more before filling tank (seems to help), pump gas with nozzle slightly out (about .5"). Last solution always seems to work.

Any ideas why this happens, and am I the only one with this problem?

PROBLEM: 6-Disc changer tray stops working after long periods of use. Car will automatically switch to Radio while playing a CD.

CAUSE: The Disc changer tray has overheated and tripped a sensor. Running the car for long periods, on a cold day with heat on, increases chances of problem.

SOLUTION: Open the glove box and remove the Disc tray. Turn off car heater. Allow at least 10 minutes of time for cool down before inserting the Disc changer tray, and attempting to play CD's again.
-----------------------------


-----------------------------
PROBLEM: Multi-function display quality decrease.

CAUSE: The multi-function display decreases in quality a lot from heat build up, and direct sunlight exposure while the car sits.

SOLUTION: Simply blocking the MFD with something to avoid direct light exposure does not to help much. It seems that heat build up mainly effects the quality of the display. Storage of car in a cool environment will prevent the problem.

Another common problems among the W202 vehicles is the Motor Mounts. According to the MB tech's Mercedes Benz never built a beter mount so that is why it has to be checked with in a year or so.

I had mine changed two years ago and today one is failing and the MB tech recomendation is to replace both mounts.

The soonest you feel your car vibrate or a rough idle check your mounts. You will loose some power since the engine is a little lower than normal. The soonest you replace then you will feel the difference in power and torque as well as quiteness.

Mercedes Earlier C Class C280 Instrument Cluster / Dashboard / Speedometer Commonly Failing

Regarding the instrument cluster needles getting stuck at 0 and then springing up to their proper place after a few minutes of driving, see this thread:

Odometer is not illuminating

I just bought a '99 c280 with 104,000 miles on it. This is my first Benz. It runs well so far. However, my odometer does not illuminate very well. I can barely read the numbers. Is this common? It looks like it's going out. Is there a fuse, do-it-yourself, or quick fix to this problem? Any suggestions/help is appreciated.

Just next to the speed meter on your odometer there are (+) Plus and (-) Minus buttons. press the (+) plus to make the light brighter or the (-) minus to make it dimer.

Enjoy

Problem Description:

Rough Idle
2 Cylinders turn of with quick acceleration
Slow acceleration

Problem Cause:

Faulty Ignition Parts

There is a switch on the brake pedal that you should check...
Easy to take it out, I can't remember if it's normally on or normally of...
If you push it by hand and the lights are still on, try to short the plug... If the lights are still on you either have some faults in the wiring (dashboard mainly) or some shorts in the dashboard cluster itself...
Better check it with a good electrician...
The car is worth the money!

Hey! Right now we're in michigan, there was a snow storm the other day, and we drove last night under winter conditions, in the 1999 C280 Kompressor there's a winter driving switch, so we use that, it helps you slow down on the turns and not slide on the ice and snow.

COOL PIC FREEWAY

 

[howsweet313]

Thank you for your post, we will definately check that out later on tonight and will let you know if it fixed the problem! Hopefully its nothing serious, we took it to the Mercedes dealership and they wouldn't tell us whats wrong, just wanted us to pay $330 for just a checkup so we figured we'll do a better job ourselves! Thanks for helping you guys :thumbsup:

Electical Problem? BAS/ASR light on

Hey everyone! 1999 C230K Can't figure out how to fix it, only thing left to do is change the oil, does it take one particular kind of oil??? The only thing we found out is that we need an OXYGEN SENSOR (anyone knows what it is?)
Thanks A LOT!!!!!!! :surrender:
