I just bought a used 2004 ML-500 last week. The dealership put it through a complete test. Yesterday, after parking to run a quick errand, I returned to find that the vehicle wouldn't start. The engine made as if to turn over, but didn't and several lights were flashing, including Low Range. I thought I'd have to get it towed, but pressed the Low Range button quickly and it seemed to release something. The car started right up, but now the Check Engine light is on and I am afraid to drive it. Can anyone tell me what may have happened? I bought this car as I trusted the dealership and just need something for probably less than 5,000 miles a year. The vehicle has started up fine since. I am new to Mercedes (my previous car was a Lexus) and welcome any feedback and/or advice about getting to know my new vehicle. Many thanks!

Welcome to the forum.
Unless you have this vehicle scanned with scanner that can access all control modules it will be hard to diagnose anything. I don't see connection between Low Range button and starting. Low Range can be engaged/disengaged only with shifter in N, vehicle stationary, brake applied. Pushing Low Range button otherwise will give you three flashes.

You need someone with a pro grade scanner or a Star Diagnostic System. I agree Witek_M there should be no connection between the transfer case and the starting of the vehicle.
That's what the dealership said when I called them. So I took the car to get scanned and lo and behold, the Check Engine light is no longer on. I've never heard of that happening. At any rate, I'm taking it in to Benz on Thursday for inspection anyway so I guess they can tell me more. Thanks for the replies!
You Need to have it scanned to determine what codes are present and what sensor or switch has failed, my hunch is the low range switch, but the only way to be certain is to have it scanned.

Yes there is a correlation between the transfer case and the no start situation. The vehicle is programmed to not start while in low range. So take it to MB Dealership and get it scanned I'm certain the code causing the check engine light is stored in memory

Well this is very odd. I have left both MLs in low range turned off the engine and then restarted them with no issue.
I am hoping to learn what the correlation is that allows mine to restart while in low range.

Whoa there.
That kind of interaction will not be tolerated on these forums.
You are far from the first shop that has tried to hand out questionable information and will not be the last.

Do you really want to be banned? Of all major MB forums this is one of the most laid back and forgiving. Also one of the two largest in the world. If you get nailed here then it won't take too long for for the other forum to know and you will not get much more love there posting the way you are.
So things got off to a bumpy start. Just reign in the anger and we can all get on the same page.
There is nothing that has been said that you can not apologize for and start working with members in a friendly fashion. Just because a member does not agree with is no reason to make hostile posts as a reply.
I have already cut you a lot of slack by letting you promote your shop in CO. Normally that is not in the rules of the forum, but members appreciate new member input like yours as long as it done in a civil manner.
This is nothing personal. As a moderator I volunteer 80-100 hours a month to just help members keep their aging MBs on the road at the most practical costs. A good shop owner and tech should do the same thing for their customers.
Please come on down to the W211, W164 or CLK parts of website and tell members how to save thousands on hydraulic roof or automatic liftgate problems. What MB wants $4500 to fix can be done for $1000 or less by a good DIY owner.
