Hello;
the flaps on my 2004 sl500 does not open.
Trunk opens but flaps do not opens so it stops there...
Flaps are tight ( installed the upgraded parts).
I am trying to determine if the motor and/or the cables connected to the flaps are broken.
From Skill module 3-3 (Manually close the vario roof) I noticed pin 5 and 5 pf connector X8/4 (trunk lid separation point) can be energized causing the flaps to move.
I cannot find connector X8/4 ...... Anyone can help?
Thank You
GP

I am not sure what the proper connector designation is, but I used connector on the motor itself. You will have to remove some trim from the trunk lid to get there. It is a simple two pin connector. Just connect 12V from the battery to these pins to see if motor works correctly. Close/open is done by changing polarity on the pins. Just like you, I was unable to find the connector referenced in the EIS.
As for cables, it is unlikely that they both are broken. With just one broken, the other flap works (Ask me how I know this).
Hello,
thank you for the help. I found the connector - it is located under the hydraulic pump towards the rear of the car. It is composed by two parts. In the bigger one - once opened - you can find the pins
Look carefully they are numbered. I got 2 x 2.8 mm spade - female connectors and connected pin # 5 to (+) 12 V and #6 to (-).
In my case the cable motor was not moving.
Hopefully that was the problem....
Thank You

Did you try to reverse the polarity? Remember, that directions for manual closing of the roof are intended to close the flaps, not to open them. Direction of the motor rotation is changed by reversing polarity on these pins.
Yes I also reversed polarity.
Pin#5 (-) Pin#6 (+) -> closing
Pin5 (+) Pin#6 (-) opens
Looks like the motor is damaged - cables maybe OK
However I already ordered a replacement
Will keep posted.
I have been having this same issue but now mine makes a noise when the car shuts off and on from the fuel saving mode like bird chirping loud under the hood. Took it to the dealer they said they lubricated the first time and it was supposed to fix it. HA YEAH RIGHT. Took it back since it was still doing the same thing with not closing and opening properly. I’ve now been in a rental going on two weeks sooo I would drop that ish off ASAP sir!!!!!
If the flaps go a long time without being actuated, either because the car was parked or roof was inoperable, the motor can freeze up. You just have to remove it, take the motor off of the gearbox, and clean everything up.

It seems an MB part number would be A2205453728. The pictures show the one I bought. It works well. I expected no joy in trying to find the correct pins and polarity in a roadside struggle, among the 13 pins present, so I wanted a plug.

Great, appreciate that detail. Did you assemble the box/battery cables yourself?

Yes. The plug came with click-in cables. All you really need to do is disconnect rear and front battery (in that order), disconnect the system plug, connect it to the battery with 'your' cable. Polarity defines flaps opening or closing, without end-stop (so one must connect just briefly).
I decided to play so I made this thing up. Led for polarity, push button for 'go' and switch for reversing polarity. Fused, of course.
The whole car is over engineered, so I thought why not go fancy..

Okay, here we go. My SL R230 2002 ~50000 miles on the clock, invented itself to be a CL! Are there any roof specialists on site :-)?
* the pump is running
* windows opens a bit.
* roof front latches open (checked with a tool that is fully open)
* the tailgate rises all the way as normal.
Then the cycle stops... The flaps won´t open but the pump keeps on running.
When you press the roof close, all of the above works normally in reverse order.
No error messages or fault lights on the display. The display shows the normal "open" and "close" or "operating". No error codes are visible with the tester (iCarsoft MB 3.0) Flaps are tight and well closed, both batteries are full charged. Enough hydraulic fluid in the reservoir. No moisture visible damages overall.
What do you think? S69/2 S69/3 switches, flap motor? fuse = where? I disconnected the trunk battery for a while too. Did not help.
2 weeks ago it worked flawlessly. Has been sitting in a warm garage all winter and I have every now and then activated the ABC and the roof mechanism.
Hobby cars!
Tried to look for some hints in the forums/youtube for solutions but find no aid yet. I don´t think it is the flap motor but you never know? Can you test/activate the flaps with the Star?
Check the S69/2 & S69/3 switch positions and S119 switch position with your scanner. My bet would be S119, it has a long plastic actuator rod and we all know how brittle German plastics are after 15+ years. If the switches check out and are changing position properly, most likely cause would be the flaps motor. Take out the whole unit, flaps and all, remove the motor, and make sure that it is free and operates with 12v applied.
Thank´s MikeJ65. I was going to put some power in pin # 5 & 6 of the flap motor connector to exclude the possibility of the motor jam. Then the S119, right. The plastic pin seemed ok on the outside of the cylinder but have to check again. :-)
My flaps problem solved! I tested the flaps and the wiring of the flap motor by supplying power to the pin 5 and pin 6 of the plug. Flaps worked fine. I checked the sw 119 and it was ok. THEN I NOTICED - the driver's rear window didn't open at all, not even from the door button. I did reset the window module without any result. At last I did reset the ad-on Mods4cars module (laptop with a dedicated software) that controls the windows and top from the remote control. That was it, all works fine now. There was no fault of the Germans engineers this time so that’s why I couldn’t see any error codes of my jammed top. Thank you all for your support, best regards from Finland. H.

Engine off, go to audio menu, Comand radio off and hang up phone with steering wheel button. SmartTop menu should come on on lcd displays in your dials.
The unit is usually installed below the bottom of the storage box behind the right seat. The bottom can be lifted out just like that, after holding two clips that are a bit hard to find, use a torch.

thank you for the quick reply . What i have under the storage box passenger side is a odd VGA type connector with nothing plugged to it .seems to be added aftermarket
