Hi all,

This moonroof reseting procedure was giving to me by a MB tech at the dealer that I bought my car from. I hope this help!!!!!

Steps:

1) Open or try to open your moonroof all the way. Once it is fully opened, push the moonroof button toward the rear passenger sit and hold it for a good 5 seconds then release.

2) Upon completion of step 1, close or try to close the moonroof all the way. Once the moonroof is fully closed, push the moonroof button toward the winshield and hold it for a good 5 seconds then release.

3) Upon completion of step 2, open or try to open the moonroof to the tilt up-ward position ( like a triangle /_ ). Once it is fully tilt, push the moonroof button up toward the sky and hold it for a good 5 seconds then release.

This simple procedure will help you to reset your moonroof.

Did I miss something? Reset it to what?

Please explain, I'm really curious. Is this for Pano roofs also? What is it supposed to accomplish?

Thanks

Hey, thanks so much man!!!

Everytime I reset the ECU via flash or battery disconnect etc, that's the ONLY thing I can't resync.

Thanks again!!!

If you loose batter power, the sunroof often needs to be reset. The symptom is that it will only move .5" at a time and stops. If this occurs, it needs to be reset and will then function normally. The windows should also be run up and down and the wheel should be run lock to lock (full left to full right) to reset everything if battery power has been interrupted.

So that's why the roof sucks in my car. It drove me crazy every time I wanted to open it, because it would just a little at a time. I will give this a shot. Thank you for posting this.

This procedure worked on my regular moonroof. I do not know if it will work on pano moonroof or not but it does not hurt to try.

Thanks for the tip! I just reset my sunroof and everything is back to normal.

My sunroof wasn't closing all the way and would stop about 3in. Then it would reopen fully. I couldn't understand why it was doing that.

Thanks again for posting this.

How do you re-set ECU via flash

great summary, but guys, I am pretty sure the procedure is in the manual. I'm in IT and hate rtfm too, but sometimes you just have to.

Just to let y'all know...my sunroof would close about half way and then go back to the open position. I thought I had to reset it or some "big brother" device got tripped. Anyway, when Roadside Assistance came to jumpstart my car (and ultimately replaced my battery), he told me just to spray the rails with WD-40...works just fine now!

Oh sorry bout that, just been "flashed" by so many different tuners at this point. When it comes back from a tuner from being flashed, gotta resync everything.

I tried this process three times and still when I press the one-touch button to close roof when it's open, it shuts all the way and immediately retracts back about 1/3 of the way.... I have to hold button to close..... so much for one touch!

Try disconnecting your battery for a few minutes to reset the sunroof, then perform the resync procedure in your manual, or above

Here is the thread/

This worked on my previous E55 -- however will NOT work on my E63, nor a friend's CLS55...

Help this is driving me nuts - Thanks !





EDIT ------ I thought this procedure worked before, but after reading my above reply maybe it didn't work ?
Trying to avoid disconnecting battery though....

Same as above ^^

Try some WD40 on the rails, this worked for me. Maybe it was just the extra drag tricking it into thinking something was in the way....

Hey we got our E55's ECU flashed yesterday.

2 days prior to that we also disconnected the battery when doing something.

So because one of those reasons the sunroof will not pop up or open. All I hear is a clicking sound and nothing else.

I can get past step one becuase it simply will just not open, anyone know what the problem may be?

i too have the stopping short on one touch feature, and when doing step 1 where it says open all the way and then hold back another 5 seconds, it broke 1 of 2 clips and now i can shut hte alcantara cover with the sun roof open....

Thanks for posting........saves me from taking to the stealership

Old thread, but just saved me from a trip to the dealer. Works on Pano PERFECTLY!!!

Step #3 was all that was needed for me

Cool beans. worked perfectly. thanks.

Just used this again.

This needs to be a sticky.
