My experience counts only for the std roof not the pano. M-B actually makes a special lubricant for this puprose. I have heard that it is expensive and not packaged in small containers. If you open the roof, you can see the rails that it slides on. I wiped away the old grease(if that is what it is) along with a few bug wings and grit. I am a believer in using their lubricants. Their anti freeze and transmission fluids are a must but in this case I sprayed a white lithium grease lightly on the slides. I don't operate the thing very much but it functions as it always did. Silicone might be a better alternative. That Stone interior in mine is a magnet for dirt, mascara, shoe scuffs, etc. I would be very conservative with whatever I used.

Thanks, I wasn't sure if MB made any adjustments besides lub'g like you described.
I'll give it a shot. The prob I'm having, is it doesn't automatically open or close all the way like it used to. I read somewhere that during this process if the s-roof comes into contact with a object. It will stop. This made me think there was an adjustment.

99% sure that is a "programming" problem. For some reason, when the car looses battery power the mirrors/ seats/ sunroof and maybe the windows have to be cycled through or reprogrammed. If you have an owner's manual, it is very simple. Maybe something like hold "open" switch for a few seconds then "close" and hold for a few seconds. I have a Japanese car and it does the same thing. Scares the crap out of you thinking it is getting ready to quit. I think you have a very minor problem. Good Luck.

- key to position 2
- press and hold (for a second or two) the switch to tilt open the roof at the rear
- check to see if roof can be opened and closed

A little off topic here but how come my sunroof and windows dont automatically roll down when I hold down the unlock button on my keypad? it was working a couple of months back but now it doesnt do anything. Does the weather have somthing to do with this as the manual states it's a "summer feature"

unc, I know I had to have it pointing in the direction of the door sensor for mine to work on my Compressor. If that isn't it. It may be a programming issue.
Barry, I was thinking of using a dry graphite lube. What do you think?

It could be a weak battery in the keyfob but more likely a defective IR sensor in the door handle. Mine has one on each side and the driver's side is broken (who would have guessed). I let the car slip out of warranty before I noticed. I think M-B removed the passenger side sensor on later W-211's. Even when mine functions, it is not much of a feature. I have to be pretty much at right angle to the car and about 10-15' away. The unlock signal will go 150-200 feet. Here in the South, the car will not shed very much heat in the time it takes to walk 15 feet. I have no idea of the material and labor cost to replace it (the sensor). (I know it is bad form to knock M-B but my Nippon counterpart goes out to 200 feet or so and is actually useful)

Its always been a warranty item for me. But how much can they charge for the lube & labor can't be more than a quarter hour. (Not that thats a bargain, but I don't get the car back with gobs of grease showing... as a matter of fact when I get it back, I can't see any grease on it, but its been lubed properly.)
