  • It hasn't happened on my E320 yet, but on at least two other cars I've owned there were similar situations that turned out to be leaves or pine needles that got into the air intake cowling and got trapped in the passageways and vents. In one case it caused ice particles to spit out of the vents when running the AC because it was clogging up the condenser unit. If you park under or near trees, you may want to check it out.
  • Diesel noise means you need new updated engine mounts. For Audio/Teleaid problems ask for a copy of the software versions of your audio, instrument cluster, and communications modules, and a bulletin stating the most up-to-date software versions! If they can't deliver these then find a new dealership for service!
  • Reading this message board really hits home! I was one of the people who bought a E500, paid full price,waited 4 months for delivery (early October)and now have had nothing but problems with the car. I have had the car in the shop 7 times and will be taking it in tomorrow for a total of 8. All the same electrical problems I have been reading about in these posts. Mercedes is telling me there is nothing they can do, ("that's what a warranty is for!!!"). I expected so much more. My next car will be a Lexus.
  • Is there anyone out there who owns a 2003 E320, and the car steers to the right, and also gets poor gas mileage? I would appreciate any info sent to me at sn654321@aol.com

    Thank you.

    I'm actually taking it back to dealer to get it checked out in a few days. I think the intake on the E320 vents have a filter, so the leaves should not be the problem. The service guy said it could be a fan regulator control unit or a million other things.

    I read a post on another site from an E320 owner who said that he drove through a deep puddle, and it shut down the engine. According to him, the dealer told him that there is some kind of air intake at the front of the vehicle (paraphrasing here, I'm not great with automotive lingo) that is known to suck water up into the engine even when you're not fording a stream or something like that.

    Has anyone ever heard of this?

    After 4 visits to the shop spanning at least a week overall, they seem to have fixed my keyless go system. They had to replace all the various antennas and sychronize the remotes. They also replaced the "gateway" whatever that is. They did have to replace my rear brake pads after a mere 17k miles. Has anyone else had problems with excessive rear brake wear?
  • Just got my e320 back from the dealership after 6 days in the shop. My complaints were:

    1. Loud vibration from the brake pump. First I was told this sound was normal. After my insistence that this noise (incessant every time I released the brake pedal)was obviously not even remotely within the range of normal even for a new type of brake system, I got results. A new pump, several new lines and some kind of dampening were installed and the brakes now sound fine. A minimal rumble is all I hear. I can be more specific on what was done if there is interest.

    2. My wife, whose hearing on the high frequencies is better than mine, complained of a high pitched whistle when the brakes were applied. On a test drive the shop foreman also heard the noise, said there was a service bulletin about that and applied the fix.

    So far 2 for 2

    3. After the first 500 miles, my engine began to sound like a cross between diesel and a sowing machine at idle and low revs. After listening to several other e320's at the dealership, we are convinced that our car is louder than the others we've heard. The dealership says the car sounds normal, but has agreed to bring the matter up with a MB rep next week.

    My experience with MB factory reps has been positive in the past. My 2000 e320 was running rough, and after several weeks of diagnosis, they replaced my engine and reimbursed me for the equivalent of month's lease payment. So we'll see.

    After this long winded intro, My question is this:

    Has anyone else experienced this loud ticking noise from the e320 engine, and what fix if any is out there.
  • I posted this messagee on another board, but it might be more appropriate here.

  • CROSSCW--The wiper chatter is probably happening because the wiper blade in not aligned properly in the perpendicular to the windshield...in other words, the "angle of attack" of the rubber blade tip is wrong. So the problem is in the steel arm that holds the blade, not the blade itself.

    NCVOL---this is called "hydro-lock" and any car that is driven too rapidly through a pile of water, even a puddle that isn't all that deep, can suffer this. Cars are not submarines and when you see those TV commercials with SUVS crashing through creeks or luxury cars thrashing through rainstorms and pushing up waves of water, you should protest to the ad agency, because they are inviting disaster. This is why the ads always say, in microscopic letters "professional driver on closed course. Do not attempt these maneuvers".

    The only sure preventative for this would be a snorkel that sucks in air for the engine from the very top of the car's roof---not a pretty sight on a Benz!

    A few cars are somewhat notorious for hydro-lock, such as the pretty little 280SLs of the early 1970s. The air intake is way too low on those cars.
  • The issue for me is how to even get close to the 16 city mpg that is advertised?! I drive like "an ol' lady" not using/enjoying the V8 and I still best 10 to 12 mpg on city? Anyone else had this experience - the dealer tells me to keep on running in the motor...?

    I have had my car since May 2003 and wish I had known of this site before I (foolishly) purchased this car based on the bad reliability reports I see from you fellow owners. Although I have only got 2500 miles on the car I have not had any bad luck of note other than less then excellent workmanship on fit & finish.

    I have not had any problems with mileage. In fact around the city the car is consistently above 16 mpg and on the highway is runs around 25 mpg. Of course I have an E500. I would think that the e320 would get even better mileage? Maybe the V8 is more efficient.
  • We're contemplating shipping our '95 E320 cabriolet to London to may parents' house. Can anyone recommend a shipping service for overseas? Car will be shipped from Los Angeles. The last time we shipped a car the radio and other items were stolen, and the E320 is in immaculate condition (only 25K miles) with all the accessories. Any suggestions?
  • I am experiecing the same loud sound from my 2002 E320 started a couple weeks ago. It happens after I drive a while and when the car is in the first gear (less than 10 mph) and the moment I release accel padel. Does any other 2002 E owner experience the same problem?
  • ncvolncvol Posts: 196
    Thanks Mr. Shiftright. I knew that you can't get engines wet, but from the tone of the post I had read, it made it sound like the E-Class had something peculiar about it that made it extra-susceptible.

    What is the required interval for trans. fluid change? every 30K or 60K? Your input please.Thanks
  • Just recently I have been hearing a moaning/droning/rumbling sound when I brake at very low speeds, 5 to 10 mph. It stops soon before I come to a full stop. No squeaking. Took it to the dealer today and they said it is nominal and normal. Right... It is very annoying. HELP!

    I have had my 2003 E320 for over a month now and with only 500 miles on it. I have already experienced some problems. First the headlights were not angled right. I couldn't see anything when driving at night. The car was in the shop for two days for that. Today I noticed that my passenger site doesn't have warm air. It only blows cold air no matter how low the temperature is in the car! The driver side is fine. Now it has to go back to the dealer again. Also I have noticed the louder than expected rumbling of brakes, especially when I am backing my car out of my garage. I am going to have that checked out while the car is in the shop. I will let everybody know how it goes. Now I am seriously considering the extended warranty.
