Hello, just need some advice. My glk sometime will not shift to reverse or neutral after driving. It always work after i restart the engine. I already replaced the auxiliary battery and main battery. It reduced the sequence it happen, but it still happening from time to time. I am thinking maybe it the steering wheel column (shift stick) acting up? I really don't want to replace parts that i don't need. Any advice will be greatly appreciated. Thanks in advance.

 

How old is the fluid, that’s where I would start. The mb interval for a change is to long, for all oils - my opinion.

 

Don't think it the fluid. I changed not long ago. The car shifts fine. It just from time to time, won't engage to gear and has to restart the engine before can select the gear again

 

Have you tried Google or links to Youtube , there are a few very detailed mb transmission videos I’ve seen

 

Yep, couldn't find much info other than people were talking about the auxiliary battery or the steering wheel column.

 

If you try to shift it and it won't, there should be a fault code.

 

My GLK250 did this a couple times before I traded it. It had about 16k miles on it at the time. The first time it was quite disconcerting.

I remember seeing 3 or 4 other threads about this behavior over the last few years. I think it was corrected with software update at the dealer.

 

No fault code and no CEL. It just happen from time to time. I am not even sure the dealer can duplicate

 

That would seem to indicate it doesn't recognize that you've pushed the lever. Why switching off and back on would fix it is a puzzle; usually that means there is a fault.

 

This has happened to me maybe 3 times over the past 4 months. No CEL, fixed with a restart.

 

What year is your GLK250? I wonder if this is the early stages of the ESL mechanism failing? If so, it's a common fault on the x204 chassis cars. From past reading, it either works or it fails in which case you can't start the car even; not sure if intermittent failure prevents shifting from/to P or D.

 

Ya, mine was fixed by restarting it. Honestly don't know what's wrong with it. If it software glitch, it will be a pain to get it fix.

 

It a 2013 model, glk 250. I think the facelifted version don't have the ESL mechanism issue. I am hoping maybe some Mercedes tech on the forum will give me some lights on how to fix this issue

 

Hey you ever get anywhere with this? Mine just did it for the first time.

 

Can you be a bit more specific?

I'm curious, because I think I may have experienced this for the first time today in our 2014 GLK350 Base (gas).

I left at 6am to go to the VA Medical Center (takes an hour to get there) and I had to stop on the side of the freeway to check Google Maps.

I slowed down (was at freeway speeds of 60+mph), stopped, shifted into Park (GLK still running).
After a couple minutes goofing with Maps, I laid the phone down and shifted into Drive (or so I thought).

Applied gas pedal... nothing (I looked down and it was still in Park).
Paused for a second. Diligently shifted into Drive - it worked. (Might have been an odd fluke)

When you shift into Drive or Reverse, do you have your foot on the brake pedal?
Do you try to shift in Neutral?
Does it show that you are still in Park?

Does it ONLY then shift into Drive or Reverse, after his problem, if you turn the GLK off, then start it again?

 

If it went right into drive and you didn't have to shut if off and turn it back on im going to say that was driver error as what i experienced and all im reading it doesn't fix itself like that.

 

Hey ​​​​​@GLK Super Fan ... did you ever figure out the this problem??

(I experienced this on Monday - would not go into Reverse or Drive. So shut off the 2014 GLK350, then started it again, and then shifting worked)

what year is your GLK? Some of the early model years have shifter rod that can misalign.

 

There must be some way to figure out what year calder-cay's GLK is. Any ideas? I wonder if there could be some kind of scanner to tell us that? Maybe some type of scanner to let us know if his shifter rod is misaligned?? I'm certainly intrigued... Do U use a scanner? Can U? i c you can. Recommendations?

 

and there it is: "I like youcanic full system scanner" jimy.j

 

What early model years? Please post a picture or parts diagram showing that shifter rod. Is it like the W204?
