#587 of 681 Navigation System Replacement? by ripleyiii Sep 19, 2006 (2:11 pm)
I have a ML500, 2002, and recently the Navigation System has been giving me a little problem. It may not come on when I start up the engine. There is a blank screen. After a while, it finally does come on. So if it doesn't work every time I start up the car, I've learned that if I wait long enough it will.   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?

Replying to: ncarrasquillo (Oct 31, 2006 8:05 am) From PHXMAX:   See the earlier postings we had on the subject (#576, 578, 579, 580) for possible causes. Mine works fine after 2 months. Good Luck.   PHXMAX
#592 of 681 Re: 2002 ML320, Paint problem [purutcu] by apryz Nov 15, 2006 (5:54 pm)
Replying to: purutcu (Nov 03, 2002 2:52 pm) I have a 2000 ML320 and the hood is full of paint chips also, but even more odd is that the windshield has hundreds of marks like it was hit by rocks.

Replying to: tommychicago (Feb 10, 2006 6:22 pm) I am curious as to the outcome of your situation. What did you do with the vehicle? Did you ever find out what the problem was? Thanks?
#594 of 681 Intemittent Liftgate Problems by gteach26 Nov 20, 2006 (7:08 am)
I own a 2006 ML350 with the power liftgate. Quite often when I close the thing I get a warning as I drive off that the liftgate is still open.   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!!

#595 of 681 Intemittent Liftgate Problems [gteach] by smart_alec Dec 06, 2006 (5:14 pm)
Had the same problem........It's well known and all MB service departments are aware of it. Today the dealer replaced the motor in my ML 350 that pulls the hatch in the last inch of travel to the latch position. Hey, it's a luxury car........MB is not going to shine you on. Take it in.
