E320 Sunroof not working properly

[desert]

I have a 04 E320 Wagon with very low miles. I went to use the sunroof today after not using it for many months ( Tucson 100+ temps) and it won't go back all the way as it did before when you press the overhead switch. It will go back a bit each time I press the overhead switch but not back all the way like it used to. Is there any way to reset it without taking it to MB and have them diagnosis the problem? Thanks, Desert

Might just need lubrication.

Possible, I'll give it a try with some silicon...Thanks, Desert

Nope, lube isn't the problem but I think I now know what the problem is....( should have read the owners manual first before posting) seems that the sun roof has to be re- synchronized every time the battery is disconnected. Had the car in MB a number of months ago for rear cargo area auto cover problems and I am sure they had to disconnect the battery for that job so will call MB Monday and tell them they forgot the sun roof when they re-connected the battery. Why does a sun roof have to be re-synchronized in the first place, typical over engineering.Desert

This is an '04 model (Which makes it 8 years old)
How many times in that 8 years have:
1.The S.R. Rails been cleaned and relubed with the only proper Lubricant
Mercedes part # 011 989 46 51 [AKA as "Gleitpaste"] ?
2.The little Black Felt covered Rubber "Feet" (AKA Sliding Jaws)that the S.R. slides on, been
inspected,cleaned and relubed with Gleitpaste ?

The Gleitpaste does not attract dust and dirt/debris unlike other lubricants.

Without proper cleaning and lubrication the Sunroof "Feet" (AKA Sliding Jaws)will grind to a halt.
But before that occurs,the clutch on the S.R. motor will B.O.

Believe it or not the service interval for the S.R. slides and "Feet" (AKA Sliding Jaws) is also the
regular Oil/Filter change interval.

So,If what I Prognosticate is true...The S.R. has NEVER been Serviced.
[If it had been serviced by a franchised dealer even one time, there would be no question,
You would still be screaming about the Bill.Very few technicians know how to work on the S.R.
AND I've NEVER seen an R.O. with the word SUNROOF on it that was less than $1,000.00 USD ]
(Idioten S.A. s think because they're "VooDoo" to them and the Techs,
You Too are scared to death of them also and will pay whatever is asked.)

Do Not Be the Unhappy Mercedes Owner Who is Crazy enough to use ONLY this pictogram to service your S.R. !
