Has anyone ever heard of this?
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.
Just got my e320 back from the dealership after 6 days in the shop. My complaints were:

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.
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.
Most ATF has color sensitive organic dyes, which fade under excessive temperatures [when they exceed the 176F optimum operating temperature.
When the color changes the product is degrading. Simple to see!
33 mpg hwy w/ac on.
1 Car vibrates and moans when depressing brake pedal-Been in for service five times-cause the SBC pump on the brake system-replaced pump,bracket , bushings , somewhat better still not what to expect from a luxury car
2 Metallic chunk going over rough road surface- fixed by replacing front arm struts
Mercedes aware of both problems -bad engineering

My E also makes the same squealing noise when I apply the brakes, but I've noticed it won't make it for the first 15-20 minutes after I start the car. I'm saving this complaint for my FOURTH visit to the dealer to the get the car aligned.
Finally, the dashboard keeps flashing a message that one of my parking lights is out, when it isn't. I'm terrified this is the beginning of the electrical problems mentioned by other owners.
I hadn't seen car quality this poor since the 1987 Hyundai I owned in my college days. Wish I could turn the clock back and have my Honda Legend back. This car is all looks -- lesson learned... stick with Japanese cars.
At any rate, seems to have taken care of the annoying but not serious problem, at least for now ).
The service manager at the dealership said it was a bad sensor. But I can not find out why this would cause a total brake failure. Apparently, the car is designed to have a back-up brake system, but they don't know how the system works or is designed and why the back-up system did not work. I'm wondering if this problem is a design flaw or just a fluke? If anyone has any ideas, I would be extremely thankful. So far I have not been successful getting any information from Mercedes on why the back-up brake system failed, or why in the first place a bad sensor shut down the brakes. It is a serious safety issue to not have any brakes, and to be told that it is not supposed to happen or it has not been designed that way just does not cut it. Thanks for any help.
The problem was not evident until I got up to 65-70mph. The car can be sent from side to side with the littlest bump or gust of wind and the steering does not seem to give warning or movement. I have had the car thoroughly tested by independent shop they say it is fine, but I think the car is dangerous. I have owned a lot of cars in a lot of price ranges and NONE have been this unstable at speed.
Love the ride around town, as this was pretty much the test drive with quick highway ride.
I can not believe that this is normal I have driven too many cars to accept that. Any suggestions of what to look for or tell the shop to look for?
The car runs extremely rich and cannot find the idle. To try to remedy this, we have tried a new mass air flow sensor, throttle body, new coils, new spark plugs, a brand new wiring harness for the computer. The cars runs fine when it is cold, but when it warms up the engine cannot find the idle, and when you push the accelerator the car seems like it is going to stall. Once the cars gets past 2000rpm it runs fine.
Does anybody have any suggestions on what the problem(s) might be? Thank you.
I have been having problems with the windshield defogger. I live in Maryland and in low outside temperatures if I turn the climate control ON, all of the windows, windshield and rear included, get badly fogged up. The moisture sometimes is so heavy that I have to stop and hand wipe it. This only happens in low temperatures outside. Keeping the system ON removes very little moisture. I took the car to the dealer and they traced the problem to faulty wiring on the AC compressor. Guess what, it is hitting freezing temperatures again and the problem is back. Any insights into what may be the issue here? Thanks a bunch.
We got 2 keys, but no valet parking key, the sales man said that Mercedes Benz doesn't make the valet parking key anymore. Is it true?? Did he lie ?
But then later on, he said that he is going to order for us another extra key, the same keys as the other 2 keys. For free. But not the valet parking key.
