MB M Class Owners Maintenance and Repair



  • Bought a ML 350 2009 for my wife and started driving it this week. Had the window down and them i heard this clicking noice every time i pu the car into a gear. Every time i shift the car makes this clicking sound. took it the MB service department and they are telling me that it is normal.

    Can some one tell me what is going on?
  • Does anyone know where to attain a maintenance manual for the 2008 ML-320 CDI Diesel? No, they do not sell this on the DVD, and the 2007 DVD does not discuss the diesel engine M-class at all. I am looking for a basic reference for some common maintenance tasks. Thanks in advance!
  • Try ebay, Craigslist, if no luck - try a search in an English speaking country in Europe.
  • I have an 05 ML 350 and the driver side parking and tail light are both not working. I have replaced both bulbs with no sucsess. Has anyone had this problem before and did you find it to be a fuse?
  • I just had the fuel pump on my 2000 ml320 changed for the 3rd time in two years, But this is the first time I hear a whistling noise coming from the Gas tank area, its obvious its the new pump, the mechanic tells me thats normal? I have never heard the pump make a noise before? Any sugestions :confuse:

    Yes, but traffic can get a little light in places during the holidays.

  • Did you ever find out if your ML350 is capable of announcing street names? I have a 2010 ML350 and it doesn't announce street names.

    A friend of mine asked me to post about his 2002 ML320. A bulb is out on the console near the mirror. The dealer says he has to replace the whole $1400 unit. Is this true?
  • The cig, lis any one had theirs blew. I checked all the fuses , but I do not see any place on the fuse box for cig lighter. Could it be a relay. Also my outlets stopped working. HAS ANY ONE ELSE EXPERIENCED this problems. I enjoy this car never had any problems and I have 172 + miles. I keep it serviced. I did research and found out the only thing that goes wrong is the windows which I'm experiencing now. I know I have to change either or a combo of 2 things the motor or the switch. Has any one else had this problem Thanks

    I JUST bought this ml 6 days ago, it only has 46k on it and it has twice now not started. It will start for about 1 second and stall out. I then get a "start error" msg on the odometer about 10 seconds after. I only have 1 key to the vehicle. I had it towed this evening to the dealership. I am wondering if anyone has had this problem. Does it sound like a bad key, a bad key sensor or something else?
  • My daughter spilled some water in the back seat and within minutes the wipers went off (couldn't turn it off), the windows rolled down by themselves, and various warning signs came up on the dashboard (i.e. brake fuilds malfunction). And then, smoke started to rise from the passenger side seat. This all happened while driving. We are thankful nothing serious happened, but this is some serious event. There is an electrical system underneath the passenger side seat that controls the electrical system and then burned out. It cost an arm and a leg to fix it but MB won't take responsibility for it. The new 2012 ML has a better design that covers the electrical panel but the older models don't. I think this is a serious defect and MB should take some responsibilty. I would love to hear others for feedback or any similar experiences. Thanks.

    I have a ML350 and my seat just started on fire. I went into the dealer and they said it would not be covered. have you heard of any other seat fires?
  • I had the same problem and they change a computer censor I do not know the name but the benz mechanic diagnose it right away and no problem since then (4 months ago).

    I have a ML350 Bluetec, purchased May 2012. The Check Engine Light came on Aug 7. It was taken to the dealer Aug 8. They replaced a valve in the emission system. The Light stayed on. It has now been with the dealer 3 weeks. In the interim they replaced an engine "computer" (by that I will presume some electronics and a microprocessor ). The light still comes on, within a few minutes of being driven.

    What is my recourse? Is there some office I can call at MBUSA (or somewhere else). Is this a lemon or is there something known going on.
  • I purchased my 2012 ML350 Bluetec back in November 2011. After 2 weeks, the first problem I had was car was pulling to the right at highway speed. After left it with the dealer for about a week, they finally realized that it was bad tire which took them a few more days to get replacement. Next, I was having problem with car loosing power when driving over a long distance or for a few hours. There is no error message on the dashboard nor that the dealer can replicate. Anyway, I start documenting them on video using my phone. They finally acknowledge but still no solution for it. Along with the car loosing power, I was getting error with PRE-SAFE Inoperative error and Ad-Blue low level warning after roughly 3000 miles. Dealer was able to rectify problem with PRE-SAFE error and Ad-Blue, but they can never fix the problem with car loosing power. After roughly 5000 miles, I have to bring the car back in again for loosing power, but this time it comes with squeaking noise in the interior as if something is loose. It took dealer a week to finally fix the problem with squeaking noise and broke the front windshield in the process which they replaced. Anyway, problem with loosing power on long trip becomes more severe as the summer in progress. I will get stranded and having to shut the car down for 30 - 45 minutes to let it reset before continue driving. I was stranded on Grapevine while driving back from San Francisco to Los Angeles. The car could not pull itself up the hill, and freeway 5 was under construction without much service lane that I can pull out. I got lucky that I hit decline and got to pull out before big rig slam into my back. It will sporadically loose power on surface street too which almost landed me into a head on collision while trying to make left turn across on coming traffic because it will not move forward. I took it back into the dealer again, and they could not replicate and cannot fix the problem. Plus, they ding my car this time. I am glad that I was thorough before driving it off the service department. They agree to fix the ding for me because it was their fault. Anyway, I have reported all these problems to Mercedes USA with all the pictures and videos that I documented, but they did not review it and did not take it seriously. Currently, my car has roughly 7800 miles, and I might have to work with an attorney to get their attention.

    Anyone figured out how to keep wipers from chattering? My 2012 ML 350 has had this problem since new. Dealer said that is just how they are, but did replace blades without improvement. The lower portion of the driver's blade carrier seems insufficiently sturdy to prevent chattering. Very annoying, especially on a $60k car. Otherwise nice vehicle.
  • My 2012 ML 350 came with one cd track and I need to know how to download to my 10GB for additional cd's? We listen to cd's while traveling and it is very difficult changing one at a time.

    I took my 2012 ml 350 for its first service (A) last week. The dealer told me that the tires need not be rotated or balanced for 20000 miles. The car has Dunlop tires. I could not find anything in the manual. Could please somebody verify it.
  • Thanks for posting your experience. I just had the same thing happen. We spilled water in the rear foot area of our 2007 ML 350 and within minutes we heard a beep and rear windows rolled down by themselves and would not roll up message said brake wear, then 2 blocks later the engine stalled and got message of check brake fluid level and electrical smoke in the car. Luckily I was able to get off the highway safely. Had to be towed to repair. Mechanic is still looking at it, but so far has found completely burned window motor.
