    Spotty & pvh3:

    I own a 2000 E430 with the COMAND system & phone which has been problematic from day 7 of ownership. My local MB dealer has responded by replacing parts and modules with no real success. Unfortunately, with the previous E-class, the electrical parts are rebuilt so I am not real comfortable with reliability over time. . . I have talked many owners of MB's who have had a variety of "electrical" problems: C, M, E, S-class cars. My problems are also intermittent which are impossible to really fix. I think the idea is to replace parts with the hope that the problem will be resolved. . .

    I have only 23,000 miles on this car and I am not interested in getting another MB at this time. I think MB needs to look hard at the supplier of the electrical components of the cars since this seems to be a problem across the entire line.

    Good Luck

    I too have electrical problems with my 2nd 2003 E-class. My current E500 radio will occassionally cut off and come back on. It starts with static which builds up until the sound goes off completely for a few seconds and then comes back on. Has anyone else experienced this same problem? The dealer has attempted to fix it (replaced communication platform and checked fiber optics). Problems still exists. Also, has anyone noticed (E500 or E320 w/Sport Pkg) that after driving and parked, it is not level??? Sometimes it is, sometimes it is not. I have measured over 1/2 inch lower one side than other. Dealer has no clue. Anyone been through this???

    hi, I own a 92 300CE. The front driver side window rolled down and now won't move at all. I have had this problem in the past before and was able to get it up again. What seems to be the problem? Could it be the battery being low? The first time it happened, it was when I left the car parked for over 2 weeks without driving it. Thanks. (oh, only the front driver side and sunroof have the problem)

    alman08, I had a somewhat similar problem with a 1992 300E. Except that both the window and sunroof acted as though they were possessed by some evil spirit. Opening and closing at will, then not operating at all. The only place where the electrical systems of these two components come together is the "Convienence" modual. It is the thing that allows you to close the sunroof and windows by holding the key in the door lock, in the locked position, for several seconds after exiting the car. Makes it so you don't have to get back in and start the car to close them if you forgot. Anyway, when this modual fails, weird electrical things happen to the windows and sunroof. I suppose it could also be a battery problem, but I would expect you would also have cold start problems. Also, these cars have such a high load on the battery they only last for a couple of years and usually fail completely when they go. Still, it never hurts to have your battery checked out. Especially in summer.

    thanks for you reply. took it in to autozone today and ran a test on the battery. result was "good battery, low charge". the guy there was confused and ran the test again. same thing. so i asked him to charge it up. after charging, ran the test and said it's a good battery. that 15mins later, he ran the test again and it said "good battery, low charge". weird. anyway, i took it back and was hoping it could do the "magic" for the window and it didn't. most likely it just needs a new battery. ok ok, i was being cheap...hhehee... i'm planning to sell the car and try not to buy new things on it, however, with the window in the current position, i guess i will have no choice. :) let's hope it will work tomorrow when i get a new battery for it.
    by the way, you mentioned you had similar problem on yours, how did you get it fixed? thanks.

    I had the "convienence modual" replaced. I forget now how much it was. .... a couple hundred probably. But it took my mechanic a while to find the connection between the windows and sunroof wiring systems. According to him, this modual is the only place (besides the battery) that these two systems come together. It solved all the probelms with the window and sunroof opening and closing by themselves or alternatively NOT opening or closing at all.
  • alman08alman08 Posts: 282
    that convience module does work on all windows and sunroof except the driver side front. :(

    The problem you are having is identical to the one I am having. It happens both with the radio and the cd changer. My dealer applied a fix from CD rom that was supposed to correct this but it has happened at least once since the fix was applied. When I took the car back last week, they couldn't recreate it so they said, you're SOL, more or less.

    As for the car not being level, I too have an E500 w/sport pkg, however, I have not noticed this. I know that the car is supposed to raise and lower itself 1 inch based on driving conditions and the suspension setting. Yesterday when I stopped at a light I could feel the car raising itself and it scared the bejeezies out of me. I never noticed that before.

    One last thing, MB should be singing a different tune very soon as far as getting these things fixed. There are MB executives in Wash., DC right now meeting w/automotive experts and such to discuss the fact that their reputation for quality has taken a serious blow. I'll keep you posted.

    Thanks for your note. I had the car in again for a "fix". They did another software update and replaced something to do with the "hands free" unit located in the trunk per instructions from the factory tech. No, I do not have the phone. I'll let you know if this works. By the way, there is a modification to make the brake assist pump quieter. That will be done next time. My car is out of level parked in the garage after driving and not running. I measure from the center of the wheel wells to the ground. It varies alot. Don't have a clue why.
  • alman08alman08 Posts: 282
    well, took that same battery out to autozone again and the guy tested it, and this time it said "bad battery". got a new one, and guess what? that window worked for 3 seconds after i installed the new battery and died again. i guess you're right, sddlw, it could have been the module that you mentioned. regardless, i think the battery was old and had to be replaced anyway.
    I have read somewhere in here that someone else's battery went out and the car died, and after installing a new battery, he had to have the radio and windows reset. you think my windows just needed to be reset?? does anyone else know about the problem? thanks.
  • alman08alman08 Posts: 282
    come to think about it... think my car is haunted?!
  • alman08alman08 Posts: 282
    just read here somewhere that a bad battery can burn the alternator! I hope I didn't do that on my car, because that new window did work a tad and stopped! With a burnt alternator, the car could drain out the battery fast, right? yikes :(

    Obviously you owners haven't spent the mandantory 2 weeks [80 hours] reading and studying [every page of] the $300 factory service manuals for your cars.
  • sddlwsddlw Posts: 361
    I think "possessed" by evil spirits was what I was telling my mechanic. I'm not sure why you say the convienence modual does not control the drivers window. That was, in fact, the window I had problems with and replacing it did fix the problem. ........ I'd go out an test the windows and report back, but we sold that E300 years ago. @!$%** thing was costing me $2000-%2500 a year to keep it running and it only had 75,000 miles on it when we got rid of it.
  • alman08alman08 Posts: 282
    what I meant was, that module does control all windows on the car, except right now when I use it, all windows work except for the front driver side.

    HELP! I'm looking for anyone out there that has had a similar problem with their 2000 E320. We are at our wits end! We have had 3 racks, one steering fluid pump and several boots and bushings replaced and still have the same rubbing noise when turning R or L. The dealer tells us that this is a "cronic" problem with all 2000 E class cars and that Mercedes is working on it. It is back in the shop today with orders not to return it until they can guarantee that it is fixed. If this is such a "big" problem then where are the rest of the complaints? Where are you! I think this is a hoax to keep us from pursuing "Lemon Law" action.

    Any insite would be most helpfull.
  • I usually follow the full size SUV boards and haven't read these posts before. Wow. This is nuts. You really have to pay some heavy dues to put up with one of these. Sure, maybe most of this stuff is fixed under warranty. But what about the opportunity costs involved in taking the car in, dropping it off, etc. etc. At least with a Bimmer you get a serving of performance with your ration of German headaches.

    Maybe the E Series-Set should consider buying what the people who work for them drive and lead happier, simpler lives? I mean it won't impress a 21 year old valet with a green card, but something with an American made, cast iron V8 that will run like a thief to 100K before it needs new coolant, plugs, etc. isn't to be sneered at.

    I would like to know why you had to have your rack replaced in the first place. We have had our rack replaced 3 times and we are in for the 4th. Dealer states that MB is aware of the problem and has processed a new TSB on the problem and has sent out new tools for the fix. However, our dealer failed to receive the new tools so they have our car for the next millenium until it is fixed. Would like to knoiw your origional problem.
  • alman08alman08 Posts: 282
    how do you lube the windows? thanks

    Re your chronic steering rack/system problem, this goes back to 1996. I have a '96 E and after numerous complaints of loud noises and stiff steering, MB dealer finally replaced rack, bushings, pwr steering pump, etc., etc. This is similar to the chronic rear and front light bulb assemblies that continued on from '96 through '98-'99 model years. Unless you make the dealer aware that YOU are aware of the TSDBs, they will continue to band-aid the problems than properly fix the problems once and for all.

    The kinds of electrical problems you guys are describing are not unique to the E class. My brother has a new CL600 that has had a lot of the same electrical gremlins. The worst one was when he got back from a 10 day trip and found the battery dead. The dealer had no idea as to what caused that. The CL600 is an awesome car--I recently drove it--but the electrical system is awesome in a negative sense.

    To: pvh3 & donk7,

    my 2003 E320 Sport also experienced the same radio problem... after some static, it shuts. This happens very infrequently.

    when you get yours fixed, please post the solution in detail.

    Thanks.
  • donk7donk7 Posts: 4
    Well, after the last attempted repairs to fix the radio, I was confident it was "fixed". Almost 2 weeks went by without a repeat performance. However, it just happened again!!!! Crackling noise which starts and builds and sound pops off for a few seconds. Back to the drawing boards...
    Also, has anyone else experienced an annoying squeaking noise from the brake pedal?? Sounds like a wet tennis shoe when the brake pedal is pressed. Mine has come and gone a couple of times. Dealer seems perplexed on this one too. Help!
  • mb2003mb2003 Posts: 7
    Donk7,

    the brakes on mine doesn't make the noise you mentioned. However, as MortorTrend puts it, it is difficult to modulate the brakes to stop in linear/smooth fashion.

    perhaps there's a fix for this?
  • dchutedchute Posts: 3
    I'm not sure that there is a TSB on this problem. The dealer has told us there is but I would sure like to see it. Alldata does not list any TSB for the 2000 E Class regarding the steering. Electrical problems yes, but not the steering. Plus we are going on the 4th rack, pump,bushing, etc. package in 3 years. I have other friends with 2000 E CLass cars and they have had no such problems. No one in this discussion has talked about this problem either, only the cronic electrical problems. I would think if this was such a "cronic" PROBLEM YOU ALL WOULD BE CHATTING ABOUT IT1

    My previous car was a '83 MB 300SD with 300,000 miles on it. I replaced in in 1999 for a '98 E-320. I have already spent more money on repairs that the entire 18 years that I owned 330SD. Newer is NOT better. Now my engine is dying while I idle on a warm day. Nothing more humiliating than to have a conked-out E-320 in the middle of a crosswalk. Folks must really had a treat to watch this old fart pushing a silver MB in his Allen-Edmunds and a tie....sheesh.After replacing the rear window motor, water pump, electrical system, and air conditioning condenser, I think I better try a Lexus - after I spend another $700.00+ or so to fix my current problem. "ain't what it used to be" - that's for sure.

    Sell it, and if you need an E class, buy an immaculate 124 for 1/4th-1/5th the price (or 1/2 if you opt for a factory fresh E500/500E) and enjoy....
  • I have a 1995 E 320 with the reputedly "bulletproof" M104 engine and about 85,000 miles on the clock. Last weekend it very suddenly started sounding like a diesel. I took it to my local Benz guy and everyone agrees I have a hydraulic lifter that is not pumping up. A very rare problem for this engine, from what I hear.

    The problem is trying to figure out *which* lifter has the problem. I can replace *all* of them, but remember this is a 24-valve engine, hence 24 lifters at around $50 each. And my technician reminds me that one of the camshafts has the variable timing mechanism making it a much more expensive proposition to remove and replace. If we were sure that the bad lifter was under the other camshaft, even it we could just isolate it to that side, it will be a much easier job.

    He took off the valve cover and checked the clearance under each cam, and pressed down on each lifter to see if one sank faster than the others. All 24 of them behave exactly the same.

    Does anyone out there have any interesting tricks for identifying which lifter is ticking, at least narrowing it down to either the intake or the exhaust bank?

    Thanks,
    ATB

    Make sure that a correct fresh oil filter is being used and all its associated o-rings are in place. Try out an engine oil flush and run the engine on Mobil1 0w-30 oil for a few hundred miles. If that doesn't cure it, use a mechanics stethoscope on a cold engine start to localize the noise to at least the cylinder whoe lifter(s) may be noisy. Good Luck.
