G500 Sunroof air dam spoiler
Hello all,
Not sure if anyone has any ideas? G500 1999T with factory ordered option of electric tilting sliding sunroof, (it's manufactured by Webasto) owned from new no one has touched the sun roof since new , but however the seal looked well tired and the rubber had gone hard so I got my local garage to change the part which I bought from Mercedes Stevenage £375 believe it or not.
Anyway seal has been fitted but the air dam which hadn't raised up for a year or so unless it was manually pushed up they decided with my authority to take it off as it was thought the two springs had probably rusted away (I had the parts diagram) or had broken so I duly ordered the springs and the carriers plus the spring end caps, so another £100 later, then the stainless steel interior embellished bar was removed and then the deflector was clipped out for inspection for the springs to do want they do and sprang off, so problem is they can't solve the deflector not raising,they have Re fitted the deflector with the six new parts, three on each side but it still doesn't spring up.
Mercedes have sent a ticket to Germany but they just forwarded the parts diagram which doesn't show the assembly method, incidentally none of the old parts were worn or broken so there must be something else, the rubber seal was very tired and there is minor signs of rust but very slight, the roof operation is almost fine but seems to need resetting if anyone knows the method.
Thank you for reading this, all the best, AC
G500 1999T Electric sunroof air dam springs, etc, thank you for looking. AC
Ed: Admin moved the pictures from the separate post to here to keep them together. Will try to rotate some
I checked mine (2012) and it is basically identical.
My air dam also came detached and to be honest there is little wind noise or streamlining provided by it, so I have left it off.
But the air dam blade is lowered by the force of the sun roof closing and pressing those silver ramp levers on each side, which in turn push the air dam down. It sounds like the lever to do this on yours is broken on both sides?
Hi bluefin,
I have just checked mine and I have taken some photos of the sides for reference in the hope this makes sense. After some sparing use of WD40 they seem to be working alright however one is much easier than the other. If you want any other photos then let me know.
Hi Jim, Thank you for sharing and sorry for tardy response, my dam finally got sorted out , we had the springs that are under the dam lip fitted incorrectly, none of the tags or carriers were broken but there seemed to be no explanation why the springs had lost there position,so I changed the springs,carriers and to be fair of the end clips, of which one appeared to be shorter than the other and both were brittle in comparison to the new ones, the dam works fine and is actually a simple fix,helped by a you tube video of a Merc specialist in the USA actually showing how to repair the dam! I will try to upload the video or at least get the web address for you and others.
Whilst my mechanic was fiddling he turned the white knob on the back of the sunroof motor and now the sunroof switch doesn't control the operation of tilt and opening and closing correctly, pushing it up now slides it back, so I am now seeking the re set guide if anyone has it! All the best everybody, Anthony C
Hello JD, thank you for showing the images, that screw, the flat head one,there is one at each end is to adjust the tilt of the dam,it looks in the right place and isn't necessary to touch right now. It looks like you need the carriers, I will take image of the six parts I replaced and it may become clearer,I will get the old parts tomorrow and try to upload photo Friday evening/Saturday, along with a you tube video of how to assemble which is on a USA Mercedes restoration specialist web site.

Thank you replying,my air dam closes just fine as the two little rods are not damaged, it's the raising, I have the problem with I have to push the dam up if I want it in the raised position, it still automatically closes again when the roof runs over the bars you are referring to. The springs are supposed to let it pop up when the roof opens but we can't work out where the springs sit now, having taken the dam off.
By any chance do you have your air dam to look at? If so the two pins that the springs fit over are they straight or slightly angled?
Thanks again for your reply, AC
