Mercedes-benz - Sl-class :: 1987 - At Start Up Shaking And Knocking Noise
Dec 9, 2013
I 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.

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!

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 ?

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).

Yesterday my 1996 Mercedes C220 would not start. It cranked like crazy but would not fire. Some things I suspect contributed: The gas tank was below 1/4 full. It was cold ... about 25F. The night before I had put 140 lb. of sand in the trunk just before driving it about 15 miles home and parking it. My theory was that because of the weight of the sand and the low gas level, gas was not able to get to the fuel pump.
So this morning I was going to put in a couple gallons of gas from my garage gas can. When I opened the gas cap there was a serious whoosh of air into the tank; there had been a substantial vacuum inside the tank. I put the cap back on, without adding any gas (the sand was still in the trunk), and the car started right up. Here's my question(s):
1) Did the sand contribute in any way to the problem?;
2) Did the low gas level contribute?;
3) Did the cold weather contribute?;
4) Do I have a mechanical problem I need to take care of?

My father is gifting me his 1991 Mercedes-Benz 300E 4matic, but it won't start. He's taken it to a specialist locally and to the dealership and they cannot find one thing wrong with it to explain why, or fix it, but every time he gets it home it won't start.

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!

My 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.

I have a 1998 Mercedes ML. In the past few weeks, there is quite a loud metallic knock when I start driving. It does not happen if I take off real slowly. What could be the cause?

My mom just picked up a 2003 CLK 430. I drove it around for a bit and noticed that a few things didn't seem quite right
The transmission seems to start out in 2nd gear rather than first even when the transmission is not in "winter" mode. The transmission is also very hesitant to downshift, and often times will not downshift at all if the car is moving.
There's a noticeable amount of lag time between when you stand on the gas and when car actually starts accelerating.The engine doesn't seem to rev very quickly or freely, and there is some noticeable pinging when the engine is under load. Performance was very tepid for a 275 HP car.
The spark plugs and ignition wires were replaced last week. The car has 105k miles on it. I know the previous owner used regular unleaded, and the owners specifically states that 91 octane should be used and goes as far as to mention precautions that should be taken should regular unleaded. The car was filled up with 93 octane fuel earlier today.
Just 15 minutes ago, I took my stepdad out in the car to demonstrate my findings. On the first drive (about 5-10 minutes) the car acted like it did when I had driven it earlier in the day (not downshifting, hesitating, lack of power, etc.), and the check engine light came on. He wanted to drive the car to see for himself. So we pulled over, shut off the engine and switched seats. He got behind the wheel, started the car, the check engine light is still on. But the car ran perfectly. It was starting out from 1st gear and would downshift promptly when give full throttle. Performance was immensely improved. The check engine light is still on though. The car has a 1 year bumper to bumper warranty. So I guess they can bring it in to have it looked at.
I'm just sort of at a loss as to why the car performed so poorly when I drove it, and all of a sudden performed correctly, after the engine was restarted.

when the temperature is above roughly 60 degrees, I can drive the car for a short while, even a few miles, and it will start to sputter and eventually stall. At that point the car won't start, it turns over fine, but sounds like it's not getting any gas. If I wait 15-20 minutes it starts fine and will repeat the same process. Is there some temperature sensor or something that prevents the engine from starting after it gets hot, or is it something else. The temperature gauge doesn't indicate the engine is hotter than normal. I've taken it to my car shop twice and they haven't found anything. 1991 mercedes e300...

My 96 mercedes c280 will not start in the winter. I moved from florida to ohio and when it gets close to freezing or below my car will not start. 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.

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 ....

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?

OK, 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.
