I had the car in the dealer's for something else. (Problem #3,490...) I asked if they would check the thing out. They did and said, the "ECU" needs to be replaced for $1,200 plus labor. (I later got them to give me the "good guy" price: $1,250 with labor. Whoopee.) The Electronic Control Unit (ECU) was for the Navigation System only. (There are many ECU's throughout the car, I'm told. This I know, because I had to replace the one for the electrics, and it was pretty expensive.) Anyway, it was "slowing burning out," they said and would soon be completely shot. I know very little about electronics, but I don't believe that an electronic control unit slowly burns out. In my experience they either work or they don't work. And when this thing works, it works. It may not come on right away, but when it does, it does.
So I asked if it were some hardware connector or something, and they said no. ECU. Replace. $1,200.
Here are my quesitons: (1) Where is this ECU? If I replace the entire CD-based Navigation System, does it also replace the ECU? Can I just buy a new navigation box and exchange the unit and all will be well? Or does it live somewhere where only ECU trained mechanics (an oxymoron I believe) know where to find it. (2) Can I buy the newer DVD-based navigation system, replace the old model and thereby fix the problem? Or do I need to replaced this ECU thing no matter what navigation system I have installed. Or.... (3) is this all a scam?
I just recently change my brake switch and light still stays on. does any one know what it could be?
See the earlier postings we had on the subject (#576, 578, 579, 580) for possible causes. Mine works fine after 2 months. Good Luck.

What did you do with the vehicle?
Did you ever find out what the problem was?
Thanks?
Sometimes it won't happen for weeks at a time, and sometimes it happens every few tries.
I'd take it to the dealer but if they can't replicate the problem I would've wasted my time.
Is this a widespread issue or am I just unlucky?
Thanks!!
The defective part is a recall item and I had the repair
done on my wife's 98 ML320 last year free of charge. Have this checked out immediately, as the defective pulley can
disengage and take out the oil pan, timing cover(expensive) and could cause major steering control issues.
The vehicle was check about 6 months ago at the dealer for the bad part number, mine was not on the list.
rebroadcast satellite signals, in many metropolitan areas factors such as physical obstructions like bridges, tunnels and even huge buldings can disrupt your radio's reception. Even the FM frequency you choose in your car can effect reception. Check out the My Sirius Frequncy Finder tool and enter your zip code to get a list of the suggested FM frequecies in your area. Good luck!

I have a 2001 ML 320 with just about 100,000 miles on it. I never had a problem starting it ultil I brought it in for body work and new brakes. I live On Long Island in NY and before I brought it in we didn't have too much cold weather. Since I have picked my car up the temperature has dropped dramaticlly and now when I start it up cold, I get that very loud whining sound. Hoever when I turn the car off and run an errand or something if the engine is still warm I dont get that whining sound. I brought it back to the repair shop to ask them about it. Since this was not a problem before the car went in but since the engine was warm from the drive over it didn't make that sound. Does anyone have any ideas? I thought I'd tap the knowladge of as many folks as possible before bringing it somewhere and being raked over the coals. I'm not sure if it could be the power steering pump because the power steering is never difficult even with start up. because of the brake work I'm wondering if anything has to do with the abs system only because the noise is similar to what i heard on my Range Rover when the ABS system started to go. I sure hope its not that but I was wondering if anyone had any ideas. Also this whining noise goes away after the car is in motion and warmed up.
Any thoughts.

The strange part is that the reception is markedly better in the afternoon / evening on the same stretch of road than it is in the morning... I'm wondering if there's some strange atmospheric thing gonig on here. In any case, the idea of extending my subscription past the six month trial seems remote if the radio is constantly being interupted during my morning commute.
I'm curious - anyone have reception problems with their satelite radio in a new M class? If so, how does it compare to any other car that you have with sat radio?
Thanks!
I also have problem the Ray Catena of New Jersey could not fix. Whenever the temperature is below 30 degree, the windshield washer does not work, possibly the washer fluid is frozen at the nozzle, or the washer pump does not work at this temperature. Anyway, so much for the German engineering, maybe they should ask Russian to design this next time.
A friend in NY bought a R500, and his Continentals wouldn't pass the NYS inspection after 15,000 miles.
It seems these Continentals are short lived overall. My CLK with Continentals might make 12k - I was hoping for 20K and I'm careful. My C320 4matic Wagon with Continentals did 35K but...just, that also seems short lived since I know other brands of tires go 50 to 60k.
Kind of painful
I have ML320 2000. when I push gas all the way, it doesn't accelerate and pushes back. my mechanic says it's not transmission, but he couldn't find the main problem yet. is it a common case for these cars , or does anyone have some idea about what it could be?
it drives fine besides that.
thanks in advance.

Would seem there is a simple remedy and repair for this... looks like the clear film protectant layer is peeling like your skin after a sunburn.
Thanks for any guidance on this.
Thanks

I would try another dealer...engine failures like that are usually recorded in the cars internal computer that the dealer can see, there should be clues.
Good luck
