Trunk opens too far ?

Good day everyone. I'm not sure if I have a roof function issue or if the rear bumper is mounted too high some how. I have a 1999 SLK230. When the trunk opens during the roof retraction sequence, it opens to the point that it comes in contact with the rear bumper and is rubbing the paint of the bumper and edge of trunk lid. Can anyone tell me how much clearance they have between your bumper and trunk when it is fully opened during the roof retraction process? Does anyone knw if there is a limit switch of some kind that stops the trunk from opening this far? The roof functions fine other that that and the trunk appears to line up with all the body lines just fine.

thank you

Mine has a gap of 13mm between trunk and bumper. I have not checked how much clearance when operating roof but no sign of it coming into contact.

Tend to think there has to be an adjustment! Car ever been damaged in the back?

I don't see any signs of damage to the car at all. There is a "Trunk open limit switch" in the back corner on the passenger side. The main lift arm comes in contact with this switch when the trunk lid is in its fully opened position. Common sense tells me that it would be this switch that would cut the power and stop the lid from opening any further. Today I will try to find a way to test this switch circuit. I have inspected all other hardware and everything else appears to look ok.

Can you hear or measure the switch 'click' when the boot lid gets to that position? Do you get a definite reading from the switch in this position? And does the boot motor logic react to this signal? That should tell you if the switch adjustment is set right or if the switch is working or if the logic sensing the switch is working.

I took the switch out and bench tested it. It definitely functions fine. I then tested the trunk lid operation and manually triggered the switch.. the trunk lid did not stop opening when the switch was engaged. I seams as if the signal from the switch is not getting to where it needs to go. I'm not sure where to look to test the other end of the circuit. (is that what you referred to as the Boot motor logic?)

Thank you

That measurement would definitely be good to know. that is one tool that I do not own but I will try to get my hands on one.

I take it your roof works as it should except for the contact with the bumper. Therefore the switch you have tested also works as does the connection to the module or your roof would not retract into the trunk. I have taken the rear bumper off mine once and it just slides straight back into place and bolts up with no adjustment so it won't be that. Do you have the 13mm (or so) gap to the bumper when the trunk lid is shut and, as measured by Padgett, does the trunk open to the 45 degree angle when in the roof is operated? These are probably 2 quite important points to check 1st before trying any adjustment or looking deeper into things.

I was able to install an app on my phone to measure that angle and it was pretty much right on 45.6 deg. The gap under between the trunk lid and bumper is only 8 1/2mm as opposed to 13mm. The body lines of the trunk lid and left and right fenders are pretty even so raising the latch adjustment doesn't seem like the right answer. The rear bumper does have the Mercedes logo and part number so I am assuming it is original. The body lines around the tail lights are also nice and even.

The switch is normally open; closing it manually as the boot lid is raising should cause the lid to stop moving and the roof panel to start moving. If you're not careful doing this you'll smash your roof into your boot lid.


Question: how did you test the switch? Exactly?

BTW it's switch S69/9 and it's connected to the CCM on pin 52 (Blue/Yellow). Be careful to find the right pin - the colors on the CCM connector are not always unique.

I tested the switch with 12v. supply and used a tail light bulb for an indicator. I manually activated the switch about an inch and a 1/2 before the arms would have made contact with it. The lid did not stop moving. I'm not sure what it is that actually gets it to stop when it contacts the bumper, but at that point, the roof retracts into the trunk normally. Where do I find the roof control module? (CCM). Is it under the hood with the other control modules on the right side?

Couple of pics of the rear gaps on mine which seem quite large when you look close.
Never had to think about it before.

Unfortunately the vario roof manual does not include a schematic but sounds like the "trunk open limit switch(S69/9) goes to the N10-3 "multifunction control unit" on pin 52. Document pe77.39-p-2000-99a.

Question for moderators: Does an excerpted .pdf of that document come under the "Fair Use" provision of the DMCA ? "Items considered Fair Use would be commentary, criticism, news reporting, research, teaching or scholarship.". I would consider adding the .pdf as an attachment to come under "non-commercial teaching".

I would not want to violate any forum rule by posting something that may help users.

ps always thought my gap to be large also but figured it was needed for the pivot.

pps if the limit switch is not stopping it then when it contacts the bumper it must be tripping an overload switch which cannot be good for it.

ppps apparently it is online, just not in English. See here.

Thanks for posting those pictures. Here are a couple of pictures of mine. My body line gaps look fairly similar I think. Part of me thinks a small adjustment on the lid/hinge mechanism would do the trick but the fact that the switch doesn't seem to do anything tells me otherwise.

The gap all around does not look completely even. I think the trunk lid would benefit from being lifted those extra 5mm at the lock. I am also sure that the limit switch must be working correctly for the roof to retract but it may have some adjustment built in. However, we know the trunk opens to the correct angle.
Has anybody come across a thread about the trunk lid being adjusted?

Have about a fingerbone when closed and less (but still a gap) when open on mine.

Thinking about the adjustment, if it did have to adjust by about 5mm then the trunk seal would probably not do it's job anymore and water could enter so a new seal may be required OR has somebody previously carried out an adjustment to stop a water leak.
You could try loosening the 2 nuts on the rear panel that hold the bumper from inside the trunk and put some weight on it and re-tighten see if it gives a bit.
