Mercedes-benz - C-class :: C220 - Inconsistent / Intermittent And Incorrect Warning Light
I have a 1996 Mercedes C220 with 60K miles on it. It runs great, but is giving me fits with inconsistent, intermittent, and (I’m pretty sure) incorrect warning lights, as well as intermittent gas gauge failures.
Soon after I bought the car about six months ago, the oil pressure warning light began to come on intermittently. Each time it came on, I checked the oil level and found it to be full.
At first it would come on, sometimes for just an instant, sometimes for several miles, but then go off and stay off for days or weeks. … Then it got weird … Each day as I was driving to work, the oil pressure light would go on - always within about 100 yards of the exact same place - about 10 miles and 15 minutes from home. It would stay on for 1/4 to 1/2 mile, then go off and stay off until the next day, when it would do the same thing again. I was still checking the oil level every day and finding it to be full; I have never added oil except when I changed it.
About two months ago I changed the oil and the filter. I put in Mobil 1 0W-40. Immediately after I did that, the oil light came on and has stayed on almost permanently. I say “almost” permanently because if I get to highway speed and then accelerate quickly, getting the RPM’s up to about 4500, the light will go off, sometimes for just a few seconds, sometimes for a minute or two, but will always come back on after I slow down.
Weirder still, immediately after I changed the oil, the coolant level warning light came on and has stayed on permanently. I have checked the coolant level every day since then; it has been full every time, has never gone down, and has never needed coolant added.
Here’s another issue that may be related. The gas gauge intermittently drops to empty, even when I know for sure the tank is not empty. Sometimes it shows the correct fuel level, sometimes it shows empty. Sometimes it will bounce back and forth between the two several times within my 1/2 hour drive to and from work. It does this with no pattern I can discern. It has been doing this as long as I have owned the car.
I have hooked up my Actron OBDII code reader to the car several times. It never shows any outstanding codes, any pending codes, or any other problems.
Although these issues worry me a bit, I have been willing to live with them, assuming there’s really nothing wrong with the car. But now I’d like to sell it - for reasons completely unrelated to the warning lights - and I’m pretty sure no sensible person would buy it if they test drove it and saw the warning lights. (And I think most people would notice if I covered them up with electrical tape!)
Mercedes-benz - C-class :: While Driving Suddenly Lights On Dash Go Out
I have a 2001 Mercedes C320 and this has happened to me twice within the last two months. While driving, all of a sudden the lights on dash go out, including speedometer, odometer, gas gauge looks to be empty, heater/A/C off - the engine still running & the radio still working. I don't know about the headlights because it was during the day & I didn't think to check. Both times it was after 5:00 or on the weekend and my mechanic was closed. Next day after starting the car everything worked again. What could cause this?

I've got a '99 Mercedes E320 and the lights have been getting brighter and dimmer depending on the RPM of the engine. For example, while in park and idle the interior lights will seem a little dim, but then if you rev the engine or start driving it will get a bit brighter.
This started suddenly last week, but I've never had any problems starting it. The water level in the battery was a little low, but I added distilled water and it's not improved.

View 1 RepliesMercedes-benz - C-class - Fuel-economy :: Idle Speed / Wasting A Lot Of Gas Sitting At Stop Lights And In Traffic
A few months ago I bought a used 2007 Mercedes C280. Overall, I've been very happy with the car. The first month or so was heavy on longer highway driving, and it seemed to be getting decent gas mileage. The last couple of months have been mostly short range city driving, and the mileage seems significantly less. I wonder about the idle speed, on the assumption that it may be wasting a lot of gas sitting at stop lights and in traffic. The tachometer reading isn't always consistent at idle, but fairly often it's up close to 9,000 rpm. What should I be seeing, and does this need attention?

The lights on rear view mirror (immobilizer lights) blink for 30 sec. I have to wait any where from 5-30 min. to start car depending on how cold it is, otherwise car runs great.
View 2 RepliesMercedes-benz - E-class :: 1989 - Whines Over 40 MPH
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!
Mercedes-benz - E-class :: Squeaky Brakes Particularly When Backing Up
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?

View 9 RepliesMercedes-benz - C-class :: 2004 - Vibration While Stopped?
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.
Mercedes-benz - M-class :: 2006 - Noise Under The Hood
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).
Mercedes-benz - C-class :: 1996 - Outside Ambient Air Sensor Gone Bad
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.
