Vario roof not working? Might be your Trunk Flap. Easy Fix DIY
If your Vario roof stops working one day, it could be that the trunk flap is not sitting tight against the trunk lid. Sensors monitor the positions of these flaps, and these sensors might not be tripped by a flap that is sagging too low. I never had problems with my roof not working, but after reading through various posts of others that had, i decided to check out the condition of my flaps. To my surprise my passenger flap was sagging quite a bit (my drivers side was fine). I then discovered that Mercedes released an updated part to resolve this issue. The new part is heavily reinforced and will resist bending much better than the original part.
Also, don't bother with the adjusting screws as they don't work very well for adjusting the tension of the flap. I ordered the new supporting parts from parts.com. The came as a pair, so i decided to install both sides. This way i will never have to worry about my top being stuck because of a silly cheap part.
Here are some pics and instructions for changing the parts.
The right side took 20 min. , and the left side took 10 min. because i new what i was doing after learning from the right. Basic tools are all that's needed, and very little skill.

Niklein,
Have same problem and tried to fix but the new part didn't fit quite well and I accidentally broke the whole bracket that houses the gearing. Any idea on cost to fix from dealer? Could I replace myself? Any help appreciated. Thanks.

hey champ,
I am quite sure it will. I just had this same issue on my 03 a few months ago. I had MB do the work though because it was covered under my after market warranty.

Did the fix on my right flap Sat night. Had a little issue with the cable drive not fitting in to the new piece. Had to do some filing to get it to fit down in properly. All done and working properly again.
The old past was clearly bent in the middle and the gear drive was barely making contact with cable drive. Would have failed completely in just a short time.

Flap Exchange procedure?
Hi,
Thanks so much for your very informative thread on how to fix a "drooping flap". This happened to mine this weekend so I was able to readily order the part and it is one its way.
Quick question.... I believe the car has a timer on how long the roof will stay open (7 minutes?) with the car running and less than that with it turned off.
Assuming this repair takes longer than 7 minutes then how did you keep the roof open to change out all of the bolts/ nuts / flap?
Thanks...David

flap snug after fix and top starts to open but the flap droops down during opening stopping the operation. when its held up flush with the trunk edge it goes down. could the cable be stretched? Holding up I see that it engages a microswtich. This happened after I replaced the support fitting as in the diy thread.

I am having the the same issue. replaced the part and fits snug when top is not open. once open flap falls when closing and have to hold the switch on the console and the flap without getting in the way of the windows when they go up. Anybody have ideas? thanks

After posting I looked at the new part again. I had to tap it on to the cable. it was not seating all the way down and the cable end was moving in and out of the new part.

I didn't notice there is an ajustible nut on the end of the cable beyond the replaced part. This well shorten the cable resulting in the rear flap to stay snug against the upper trunk margin engaging the microswitch to continue top operation.

Roof Flaps not folding
Thanks for your post! Solved my problem quickly after an 871.00 non-repair,two return trips to the dealer and two road-side service calls.Highway (pun intended) Robbery.Certainly even "high end" dealers have not the highest of scruples.

Just ordered the parts, flaps in position, need to lower top
Just ordered the parts, flaps in position, need to lower top. Until I get the parts I need to lower the top or raise it would be nice. Hung up in half way position. checked that flap micro switched are engaged, still wont complete cycle. Is there a reset procedure? Or a way to get the top all the way down so I can drive it? Thanks, Stu

I just completed this fix. A couple of helpful hints. These relate to replacing the parts when your top is stuck in the closed position.
1) The new parts come untapped for the torx bolts. The bolts are self tapping.
2) Before installing the new parts loosen the cable adjusters by screwing them counterclockwise about 4 full turns.
3) You need to tap with a hammer the new part onto the cable adjuster so that the slot on the adjuster has enough room for the new part to slide into.
4) When attaching the new part to the flap make sure the flap is in the up position and the cable is routed behind the flap.
5) After the flaps are re-attached you will need to adjust the tension of the flaps so that they are tight to the trunk carpet. Do this by turning the cable adjuster clockwise, then tighten the lock nut.
These hints will make more sense once you are trying to figure out how to put ii back together. The second one takes 15 minutes, the first one you do will take a lot longer.
It definitely solves the problem though. You will see that the original parts bend enough so the gears do not engage.

They are wrong. It is simply a part that was under engineered by Mercedes. The new part cures the problem without any need to repalce the cable. The old parts are clearly bent as I have noted. If you don't want to attempt the fix yourself you need to find an Indy that will do it for you. In reality it is a pretty easy fix. Just takes a little time and patience.
