Mercedes-benz - C-class :: CEL Starting Blinking And Car Idling Extremely Rough
Mar 22, 2015
Recently I brought my car for an oil change. They put the recommended full synthetic oil in and when I left the cel starting blinking and the car idling extremely rough. I brought the car immediately back (only drove ~1/4 mi.). They discovered that they put too much oil in the car. Despite their efforts of removing oil and changing filter x2, they could not get the cel to stop blinking or the car running correctly. I brought the car to the closest repair facility with diagnostic capability and they noted the car was still 1qt overfull and multiple misfire, and cam shaft actuator codes were happening. Car was towed to dealership where they diagnosed fouled plugs attributed to too much oil. Oil change facility paid towing, repair and diagnostic bills for their mistake. In the subsequent 2 weeks my car was towed two more times to dealership. Once for going into limp mode after misfires and once for fuel pump dying. Is this all a coincidence or could this be repercussions from botched oil change? Dealership says it is just coincidental.
Car is a 2007 Mercedes clk350 cabriolet.

My 2000 Mercedes C230 Kompressor's been riding rough, particularly at low speeds and when idling. I took it in to see if engine mounts needed replacement, and yes they do, but my mechanic also found that I've blown or cracked the head gasket. Coolant has solidified around the gasket, keeping it from leaking now, but he indicated that with the next rain, that solidified coolant would be washed away and the car wouldn't be able to hold coolant. The car has 160,000 miles, recent brakes and tune up (should he have seen the gasket problem at tune up???).

I've got a merc C230 Kompressor that has 174k miles on it. The car typically runs really well and is not underpowered or anything. Last weekend I took a road trip that was 400 miles or so. The car did fine for the first 300 miles but then began running rough and was underpowered. Was acting like there was a fouled plug. I pulled over and stopped the car where it sat for about 5 mins. When I restarted the car, it was back to normal, with a smooth idle and not underpowered. It ran fine for about 30 mins and then began running rough and underpowered. I find that when it starts running rough, if I stop the car and turn it all the way off for at least 60 seconds, then when i turn it back on it will operate normally again for a bit. This also only seems to be happening when its really hot weather, 90 degrees F or higher.

2000 ML430 230,000 mi. The engine starts and all is fine until I hit a spot of rough pavement or a minor bump and the engine "stumbles," feels like it has cut out or starving for fuel. I have been unable to tell whether it is left front or rear right tire or corner of the car that hits the bump and starts the engine running on limp home.Once it happens and I stop at a light then hit the gas, I can count to 4 before the engine responds, making left turns dangerous. MB factory service since new. The dealer has replaced spark plug wires, spark plugs, crankcase sensor, gas pedal sensor and still the same problem. I think it is a loose wire or ground since it only happens after I go over a bump(even a seam on concrete any jiggle does it).

I filled up my car at the local gas station. It had been raining non-stop for the past three days and nights. 10-15 minutes later as I'm stopped at a light, the car starts shuddering, almost stalls a few times. Rough idle all the way home.
I limp home, guessing water in the fuel. Next day I go to Advance Auto and buy some fuel additives which are supposed to solve the water problem. The guy there mentions that he's had a number of reports of similar issues from this particular gas station (it's now out of business, go figure). Additives make things better but not fully.
2 tanks of gas later now and the rough idle is much better but not gone. Car seems to have less power and sounds a little bit raspy on acceleration (not noticeable unless driving near a wall which can bounce the sound back). My guess is that one of the cylinders is not firing, maybe needs a new spark plug?
The more worrisome thing is that as the car has started running more smoothly I've also noticed a smell of gas after startup (may still be there when running but I don't notice it then) -- coming from the exhaust. This seems to be in-line with the missing cylinder theory but I'm running blind here as I don't have much experience on this topic.
The car's a 1997 C280. 130K on it. It's old but mechanically the thing has been a tank so far (Inline 6 I think) -- very sturdy and responsive. I'm hoping that this whole ordeal hasn't done permanent damage.

I have a 2001 Mercedes E class, 4Matic. Over the last 7 years the ABS (Anti-lock Braking System)/EPS (Electronic Stability Program)/BAS (Braking Assist Program) warning light comes on and when I stop the car and start again, the light goes away. When this light comes on, only thing I noticed is the cruise control does not work, otherwise, no other problem. I took it to the service station one time, but that light did not come on and they did not do anything.The car has 105,000 miles. Now, when the light comes on it stays on longer and sometimes, I have turn the car on and off several times before light will go away.I am afraid to take it to the Mercedes dealer, as they might find a problem when no problem is there. Whether this is just glitch in the software or there is a real problem.

I have a 1989 Mercedes 300F, automatic transmission, with 175,000 miles (give or take). It runs great, starts well, we have no problem driving it 30 miles back and forth on back roads up to 60 mph. The problem seems to be when driving 40 miles at 75 mph. At that point, it will start to run rough, and then will not go over 40 mph without whining. The first time this happened, I had a leak in the transmission fixed and fluid put in. The second time, I had the fluid and filter changed, a new alternator, and a complete tune up. For a month after that we drove it for miles but not on the highway, with no problem. I thought I would chance it on a longer trip, got 40 miles down the highway at 75 mph when suddenly it started acting up and had to call a tow truck. When the tow truck arrived, we did not see any fluid under the car. It's been sitting in the driveway and now there are fluid leaks (appears to be oil). So, does it sound like something in the transmission, or maybe a bad alternator?

The check engine light is on. Yesterday twice I had the situation where when I turned the key to start. The starter motor was crankin and it was not firing. I pumped the throttle a few times to let air/gas into engine. I also opened the gasoline tank cover (where you insert the nozzle to pump gas) for a few mins and then shut it and started the car. It started. After running for 20 mins it happened again. The starter motor has to crank for some 10 seconds before it fires. Then no issues. What do you think it is??? Battery is fine, starter motor is fine since its cranking away. I am suspecting fuel pump ?

I have a '05 Mercedes CLK320 convertible that I purchased 3 years ago with about 29,000 miles on it. Two years ago the hydraulic lines in the top blew and I spent about $3,000 to have it repaired. Today, the lines blew again. What I'm trying to find out is: - Is this common in this car? Or in any convertible?- Did I just get a lemon?- If this isn't a common problem, should the dealer that repaired the hydraulics 2 years ago fix them again for free?
It only has 70,000 miles on it now and I was under the impression that I could drive a Mercedes for a couple hundred thousand miles without a too much mechanical problem. But if this is going to be an ongoing issue, I'm going to get rid of the car, even though I absolutely love it. It's ruby red, of course!

My brakes squeak from time to time, particularly backing up, but also braking forward. My mechanic said I have plenty of brake pad and nothing is being damaged. He said he has often seen the "squeaky brakes" problem in Mercedes and it is often difficult to pinpoint which wheel (or wheels) would be the cause of the squeaking (sound like metal on metal). Why this is happening?

I own a used 2004 Mercedes C320 4Matic. I bought it with 57k miles. I drive it about 150 miles per week. The reseller told me i needed engine mount replacements at 67k. The car did have a vibration, which I was sort of ignoring, so I had the work done. Now, the vibration persists.
It is most noticable in the morning upon start-up, at an idle. But it is also noticable when the car is warm and I am stopped at a light. It can also be noticed as a subtle vibration in the steering wheel at highway speed.
I am very sure it is not wheel balance or rotors (hey, I can feel it at a stop). I brought it back to the dealer, who said after 5 hours of diagnosis, they could findind nothing wrong.

Last week I noticed that my engine (2006 ML350 33,000 miles )was not sounding as it normally does. I called my foreign car repair shop that normally maintains my car but could not get an appointment for several days.
My husband thought that it was possibly a bad bearing in one of the belt pulleys near power steering pump. The noise was getting louder so my shop looked at it sooner and determined I needed a power steering pump, reservoir, gasket, fluid,accessory belt tensioner and belt.
I had no choice but to get the repair.When I picked up my car it still didn't sound right. I was told it would take a little time to break in. Well all week my car was making a lot of different sounds until it got so loud I wouldn't drive it. I took it in today and got the call that it needed what I think was called a/c tensioner pulley. I just want to know if this seems possible. (Car drove fine and no problems with steering before first repair).

I have a 1996 Mercedes C280. The outside ambient air sensor has gone bad and now reads about 30 degrees F high. There are two types of sensors for this model and year. One is a plug-in sensor that looks like a small pointy cone. The other is a long cable with a metal cylinder at the end that looks like an old-style stereo headphones jack (the thick kind). I have this second type.
I would like to know whether, instead of replacing the whole wire and sensor combination, which involves taking out the instrument cluster and rerunning the wire, I can simply cut off the wire at the sensor end and solder in a new sensor (cut off from a new part).
I am wondering whether it would be possible to just cut the existing cable near the sensor end and then solder in one of the pointy cones. There is a youtube video that shows replacement of a similar type of pointy cone sensor on a BMW, and it looks like the assembly that accepts the sensor is the same, so if I couldn't find a Mercedes plug-in receiver assembly for my old car, I could maybe use the BMW one and then plug in the Mercedes sensor. That would let me do another plug-in later without resoldering.
Since this sensor has gone bad once before, I have to think that a replacement won't last more than five years or so.
I am not sure whether the outside temperature has an effect on other aspects of the car, such as injection mix. I presume it has to go through the on-board computer, because it must be the signal for the little snowflake that appears on the dash when the outside temperature drops to freezing at the road level. Whether leaving the sensor alone and just living with a high reading will cause problems? Right now when the outside temp is around 70 degrees F the sensor reads about 105 degrees F.

Last summer my air conditioner (cooling) stopped working. However the heat has remained on and is very high, even though it is not turned on. How can I turn the heat off?

I have about 25K miles on tires that are expected to last for 60K miles. The tred is fine. But I have experienced occasional serious shaking of the car when going at high speeds. Not every time. And it has only happened when I am alone in the car (of course did not happen with mechanic in the car). My mechanic says I need an alignment and new tires, claiming that by being out of alignment the tires are ruined. Says it is heat and road conditions that cause the effect and there is steel belt damage within at least one of the tires. Curiously, the car does not do the classic out-of-alignment thing of pulling to one side. Not at all. Is it an alignment and tire issue or something else? The car has 175,000 miles on it and otherwise run great!
