I have a serious suspicion that I have a timing chain rattle. Using a pipe I located the sound to the front of the engine. It ticks much faster than the injectors like more than ten times faster. There are a few different parts involved with the timing chain tension. I have 150k miles on this car.... MB 1995 c220 ....
View 2 RepliesOver the winter the car starts right up and you can actually see the STEAM from exhaust, no shake. when the weather gets warmer it drives weaker, shakes more with black smokes at times especially at low RPM ~600-700. I put the car on neutral at stop so or I press on the gas paddle a bit to get less shaking. On cylinder 1 there is always a small pool of diesel at the injector nozzle. I have also turn the idle adjustment pin 2 or 3 times so the car won't idle at 3-400rpm and shuts off when there is strain on the car. 1995 Mercedes S350D....
View 6 RepliesLast 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).
My 2001 Mercedes CLK320 has ~150k on it. The maintenance etc. has been kept up to date. A few months ago the car engine started to run noisily and began to vibrate. It's worse when it's cold out or if the car is at stopped but not in park (like when you're at a stop light or drive thru). The vibration and noisy engine running lessen considerable after the car runs for a while and if the car is in the park. I already had a tune up by the MB dealer about 9 months ago. Diagnosis? Also, I'm obviously at that point where the dealer service shop no longer makes sense. I'm going to drive this car (hopefully) beyond 200k, however, it would be nice to get rid of this problem. Otherwise, the car really is almost as good as new!
View 7 RepliesMy 1999 Mercedes ML 320 with 180K started ticking when my wife turned the temperature control from cold to hot last week. Before this, it ran fine with a fairly new a/c installed - ~1 year ago. It was a cool morning. I started the car and she turned the control from blue to red. The ticking sound started immediately and only cooler air came out.
The a/c also does not blow cool air anymore either. The ticking is constant and low when the controller is in the blue and louder and faster when the control is turned to red. What happened, what the problem may be, and repair options? I haven't taken it in to my mechanic yet and would like to get some preliminary thoughts.
My neighbor have a neglected 1995 Dodge Ram with the 3.9L V6. This engine is called a "Magnum" but I have to say it is pretty gutless overall. Anyway, it has the famous clatter caused by the timing chain tapping against the timing cover. Every one of these from this time period sounds like this and I understand it is a common problem. Is this a critical problem or not? I understand it can be fixed by replacing it with a newer style timing set with a tensioner. If this won't cause damage, I say leave it alone as the noise is just a minor annoyance. I was just in as far as the water pump and was tempted to tackle it but figured it could wait.
View 10 RepliesI got a Mercedes Benz, SL560, US style, 8 cylinders, from 1987, mileage around 130 000I got the camshafts, rockers, and valve changed these days as the lifters were a little worn out as I was told. So I decided to do it now than later. But since the mechanic changed them I get a bad knocking noise and shaking at start up. It disappears after up to 5 minutes. The mechanic said he only changed the parts. That's it. Nothing else done. When I was there doing the work I say him using the chain. I left the shop as I could not wait till the work was done.
Someone told me that the clearance of the valve has to be checked and adjusted. Mechanics say that it is not possible as my engine is W117 and there is nothing to adjust. It will do it automatically. I took the car back as clearly that mechanic could not do anything else then for the car. He also does not want the car back. He hung up when we tried to ask him to check the car again (like checking the timing chain). Well. In between I asked another shop to check it. They replaced only 3 rockers again. They were new!!! There was a slight damage on them. I guess this is the part of the rockers where you put the screwdriver on. That is why it was a bit "damaged".This second mechanic said I should just drive the car as the problem will be less in ... dont know when. Hundred of miles, days, weeks?
I am not satisfied with this situation and therefore I am here to ask what the problem might be. This wasnt there before the camshaft was changed!I cannot really make the mechanic do what I am asking for. I am now in an asian country and they do what they wanna do. I am only there to pay high prices and nothing is done what I wanted. With this mechanic I am trying to get him to check the timing chain (chain tension) and plastic guide rails? Could this cause the problem or also something else?I wanna know what it might be so that I can tell mechanic when he picks up the car.
This morning while listening to cartalk I am stopped at a stop sign. I press on the gas to start off from stop - hear a loud bang as if I hit something. All of a sudden my engine is revving hard, whining noise but no power to drive. Luckily I had enough gradient to put the car in neutral and float it to a stop by the curb. Car does not move on Drive or Reverse but engine runs fine and revs up but no power to both axle. Where the issue is? The car is 82K miles and has driven great. where is the issue??? Axle break down/ CV joint break down/transfer case break down/ What is it?
View 18 RepliesOK, so this is a 2012 ML350 Blue-tech with around 31,000 miles on it. Lately when it is warm (either by driving for 30 minutes or more, or by outside temperature of 80 plus), it has been making the strangest front end groaning noise when coming to a stop and when pulling away. It sounds like the front end suspension is "groaning". It doesn't have to be a hard stop, gentle will do just fine. The car comes to a halt, the front end dips slightly - "groooaaan" (perhaps more on the rebound than the initial dip). You start up again, the front end unloads, and "groan".
Very disconcerting on a car as smart as this. Tom and Ray know this car - this is the one with the "smart radio" (switches channels at voice command…) The dealer is stumped. They have the car for the third time now and even though both a mechanic and the shop foreman have been shown the problem (taken for a test drive ), they have been unable to come up with either a diagnosis or a fix. They replaced the front sway bar links once to no avail.
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.
View 1 RepliesI 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?

I walked to station got gas put in the tank the engine would crank but would not start. I got towed home and still will not start. It will crank but that's it. 3.0 L inline 6 300 E ...
View 5 RepliesThe 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 ?

View 3 RepliesI 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?

View 9 RepliesI 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.
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?
