    My check engin light came on along with "engin electronics" light. I scanned it and scanner listed ( PO 173 Fuel trim / malfunction /bank 2 ) I re-set light and it lasted 8 miles and back on again same codes! Does any body have any idea what to fix or repair??
    thanx, BB

    There is a damper valve that can be installed to help reduce the "SBC" hydraulic unit noise to the point where it is barely perceivable.

    Thank you. I will try again with my dealer to solve this noise problem.

    I have a new E350 2006. Owned it for 6 weeks and it has been towed to the dealer for the second time in that period. Car wont start. First time, they replaced the alternator. Ran fine for 4 weeks and today would not start. Nor would it take a jump start from Mercedes roadside service mechanic. So it was flat bedded to the dealer. This is Saturday and they wont see the car 'til Monday. Any one have a simular problem?

    I have the same problem and got the same response from the dealer... It is truly an embarrassment for a car like this to have some many problems.

    Notwithstanding the litany of concerns expressed about specific problems with this car, would anyone here still recommend buying one?

    I like the car, but admittedly, I am more than a bit squeamish. Will these problems be correctable or do they represent, in your exeperience, problems that will likely stay with the car?

    That will depend entirely on the personal experience of the person you are asking. There are plenty of instances here (or more accurately the E Class forum) of people who have had flawless vehicles. That has not been my experience.

    When everything is OK with my car, I absolutely love it. It has the exact combination of features, size and style for me. When I look at cars that I would purchase now to replace it, I just can't find one.

    That said, when I have a problem (and for me that has been frequent) it is excruciating. Again, THAT experience will differ from person to person. Some people here have access to service departments that solve the problem quickly the first try, give loaners no questions asked, etc. That has not been my experience (even though I followed Mr Stroudmans advice and paid full price and continue to frequent the dealer that I purchased from).

    So, based on that, Mercedes would have to pull off an AMAZING turnaround with respect to quality in order for them to extract nearly 60 large from me again.

    I took the car to the dealer and my advisor listened to the noise. He said it sounded like a valve noise. I got real excited about possible solving the problem. He took the car inside th shop and had his service mgr. listen. When he returned he told me "there is nothing they can do, this noise is part of the hydraulics" It's no wonder Mercedes is losing money. Multiply me and my family and friends who are aware of this annoying problem times the number of vehicles sold and you have a long term loss of buyers. I don't know how I will be able to live with this noise for the length of the lease. Thanks for trying to help.

    My 1999 E320 has similar issue. The radio is fine, but this week, it stopped recognizing the CD changer. Pushing the CD button brings the message "No changer."

    Did you find a solution to your problem, short of changing the changer?

  • I had a similar issue with my 2004 E320, the dealer installed a felt pad to isolate the pump motor from the rest of the car. It worked! Sometimes you can hear and feel the pump work, about every third time the brake is depressed, but it is SO MUCH quieter.
  • Any ideas on tire life, more specifically tires that become SO NOISY that they must be replaced! I have a 2004 E320 w/ Appearance Package (17" Sport rims, etc.). No complaints on handling, braking, etc., but the caster/camber (?) are so aggressive that the tires develop horrible cupping patterns and hence become very loud when driving slow through the neighborhood or braking on a smooth road. I know it's time to look for replacements when people look over and give a look like "what is wrong with that car". First set of Michelin's lasted 13K and now have 5K on a new set of Bridgestone's ... 2 dealers say the alignment & balance are OK, but that I need to rotate the tires every 5K (I have done this religiously every 3K).

    Any ideas? Thanks.

    nickthewabbit, what tire pressure are you running? maybe you need to bump it up a bit. 34 psi cold perhaps? if the outer edges are already cupped, going beyond 34psi cold might reduce the noise, it will cause the center of the tires to carry more load than the edges.
  • My 2004 E320 (one of it's SEVERAL electronic issues) left me stranded at SMF airport. I returned from a five day business trip only to press the key fob and nothing ... it is at this point that you quickly learn why MB built the mechanical key into the fob. I got the MB fixer van out, they replaced the battery w/ an inferior C class unit (color was different) - I was off after that. The mechanic told me that this is common and he responds to several E's and S's per week with dead batteries. Evidently a few rogue electronics will refuse a command to stop working when the ignition key is removed - i.e. auto leveling, power assists, power brakes, etc. The MB fixer returned to my home with a new proper power cell and all has been well ... I have a personal issue with ANY car that leaves me stranded, to me that is the ultimate no-no for a $58K auto. Maybe an Audi next? Can't do it, I really enjoy the Benz when all is well ...
  • Elias - I have been running cold psi per the MB sticker on the fuel door (cannot remember the exact amount). I will try bumping up to 34, that sounds like a good idea, much more affordable than a new set of shoes. Thanks.
  • I leased a 2004 E320 just over two years ago and I only wish I had taken the time to review forums such as this 29 months ago. I see the same aggravated customer complaints that I have experienced and I see the same lousy treatment by Mercedes and the Mercedes dealers reported on, by many unhappy customers.
    I have had numerous electrical issues including a defective stereo, headlights shorting out when I go through a carwash, mirror signal lights shorting out, front signal lights shorting out when the car goes through the carwash. The moonroof sticks open occasionally and just keeps opening up over and over again on its own.
    The rear struts both broke at between 10,000 and 20,000 miles. ( at separate times because they never fix anything even though they know it is defective). The front control arm on the drivers side was the last thing to just "break". Upon inspection they determined that the front coil springs were also defective. Upon tearing it apart further on my insistance they finally determined that the entire passenger side was shot also and they reluctantly replaced that also. The front end of this piece of crap car now clunks every time my wheel drops slightly into a road dip.
    The attitude of my dealer in Massapequa, New York has been one that would shame any legitimate dealer. They told me the problems with the radio was unusual which I since found out was very common for the series of malfunctions. The service manager told me that the electrical issues were unusual but my service advisor pulls a bag of blown bulbs out of his desk drawer showing me what a common problem it is. He also tells me he never saw these type of "minor" problems at a different manufacturing company that he used to work at. (Starts with L). The service manager tried to tell me that the bulbs did not short out but rather were just worn out. Upon my continued screaming in the middle of the dealership that THREE LIGHT BULBS (that is $274 by the way) cannot short out at the same instant as they pass through a car wash they finally sent me home with my three lights replaced under warranty. A couple of months later the service manager then tells me that the shorting problem was my fault because the car had body work (which it never had) and that the seals were not properly done. Once again they sent me home with my free light bulbs replaced because I refused to leave the showroom floor to discuss the issue. Amazing how many customers AND MANAGERS listen when you do this in the showroom!!!!
    The strut problems the same service manager tried to blame on excessive mileage (first at 10k, second at 20k, third and fourth at 70k).
    To my amusement and pleasure this service manager was dumped the last time I went in and I spent a few minutes talking to the new service manager. He confirmed the issues that I referred to and told me that they were not that unusual, unfortunately, for my year and model car.
    The unfortunate thing for Mercedes is that it was obvious that no one cares. I got through to regional managers who just send you back to the local dealer. I got through to a corporate manager who only referred me back to my local service manager. What they do not seem to care about is that customers like me (54 year old married professional) buy two new cars every 2 to 3 years.) I have owned Corvettes, Nissan 340Z, Saab Aero, Audi's, Dodge Stealth, Misubishi Diamante. Mitsubishi 3000GT, Subaru's, Mazda Millenia, etc over just the last few years and I have never had such a miserable experience, IN GRAND TOTAL, from all of those other cars and dealers combined.
    I now go out of my way to be sure that I tell my story to anyone who is interested as to what a lousy car Mercedes has made and most importantly what a LOUSY COMPANY MERCEDES has proven to me to be. Problems can happen, especially in a redesigned car, but the lousy attention to customer needs and problems, have to be deep seated in Mercedes, right from the top.

    NEVER EVER AGAIN. Buy any other car but don't get sucked and treated as if you are the problem. The repeated stories about Mercedes quality dropping fast are not exagerated.

    So sorry to hear about your problems. Your understandable frustration would come through clearly even if you didn't use bold typeface.

    I suggest you come over to the cross-manufacturer forums such as "Luxury Performance Sedans" or "High End Luxury Marques" and share your experiences there. You'll probably get more response than on this particular board.
  • See my comments and experience at #534.
    If you haven't decided yet you should run the other way... as fast and as far away from Mercedes as you can get.
    Worse than the car performance is the prevailing company attitude that seems to say "all customers suck and nothing is wrong with the German engineering".
    Just read all of the other experiences and look for the common threads. Unfortunately I didn't look and I certainly didn't heed the quality warnings over the last few years for Mercedes.
  • I "SHOUT"as loud as possible so that people don't have to go through the same lousy experience as I have had to with a Mercedes.
    I have run companies as large as $45,000,000 and have worked as an executive in the 8th largest corporation in the world and I have never seen such poor customer concern and service as these clowns display.
    It is no wonder that the ratings for Mercedes continue to drop.
    Where do I find those sites you mentioned?
    I actually just stumbled across this site trying to do some proper research for the purchases of my next toy.

    As a MB owner (and coincidentally a 54 yr old professional) who recently bought a Lexus LS largely due to reliability concerns, I really do understand your pain.

    Check out High End Luxury Marques and Luxury Performance Sedans

    I think you'll find them entertaining to say the least!

    If those links don't work for you, just go put those forum titles into the Search Forums "Enter Keyword(s)" box in left hand column.

    To Post #534, I've had a MB since 1994 and can't say I had lots of problems. Therefore, "too bad, so sad". What do you expect, it's only a car.
