low range light

hoping someone can help...

i have recently purchased an '02 ML500 , one owner, low k's, full dealer service history etc etc.

in the last week or two, the 'low range' warning light flashes for about 10 secs when starting up.

on calling the original dealer and explaining this, i was told that it needed a new 'low range motor' and this was common fault for this series.

so i guess my questions are
a. is this a common fault? (having scoured the first 12 pages i couldn't find a thread)

b. what is the part number for the low range 'motor' (as it was described to me)

c. is there an online seller of such parts.

any pointers appreciated!!

I understand that the low range motor is the one and same as some windshield wiper motors. You can get more info at: Wolfgang's ML Page: M-Class lockers

low range light

There is a procedure described in the link below that you may want to try before buying/changing any parts.. I tried that procedure, too, and it worked fine for me.. There may be something getting out of sync from time to time..

After all these years of owning my current 2005 ML 500, it is a major unreliable vehicle with a very large/expensive repair/defect history and has been like this since brand new.

low range light

Just this weekend, I had this problem reappear. Everytime I started my ML the low range light will begin to blink.

I performed the steps described in the former posts, (starting the engine, putting it in neutral, pressing the low range button once, wait until it finish blinking (heard the low range motor engaging), turned off the low range by pressing once the button, waiting until the light stop blinking, and then turning the engine off).

After I restarted my ML, the low range light will not blink any more.. I am sure it will be ok for a couple of months. My former 2001 ML 320, never had this issue in all of it's 108,000 miles.

I wonder what is getting out of sync or when this happens. Maybe whenever I perform something in a particular order, it triggers this problem..?

I had the same problem and my mechanic just took the motor off and re-lubed everthing to get it unstuck. He told me about once a month, or more, engage low range and drive around the parking lot or if you have a short post office run, grocery store run, ect. do it in low range.

low range light

Does your low range engage correctly when you turn on low range mode? If it does not, then you may have the low range engagement motor problem or some other issue. In my case, the low range motor engaged correctly, and only at startup would the low range light blink several times..

I'm not really sure if it's working or not, I have only used it once and that was last winter. I turned it on and then drove it for a while but it didn't feel any different than it normally does. I'm assuming that is not how it's supposed to be.
If memory serves me correctly when I did have it in low range last winter it was like you put it in granny gear. I didn't feel anything like that when I put it in low this time.

The light only comes on when you first start it, it will blink about 4 or 5 times and then go out.
I didn't even think much of it until I saw this thread.
