Electronic trunk closer
Has anyone had any problems with their trunk closer? Once in awhile I can hear the closer 'prime' but it doesn't close. Then when I press the button again the trunk closes without the closer primeing. It seems like it sometimes fail to engage.

No problems here however, you should have it looked at. Mention DTB - P-B-80.20/34 AUG05 Remote Trunk Closing Non Functional. The potentiometer (part # A211 820 15 97) on the trunk lid drive unit may need to be replaced.

Potentiometer? Konigs....you and your big fancy words.
Are you sure the problem isn't the flatulation modulator?

the sound of the closer "prime" is the sound of the LATCH (that sits in the plastic panel opening just above the bumper) going up...once that latch goes up (pressing the opening/closing button) it STAYS up for a while so the second time that you hit that same switch the LATCH does not have to go up again
If the trunk has been open for a while - the trunkcloser goes into some sort of "sleep" mode after which it might be that you either have to press the closer button longer (keep it pressed for 1 second) or press it twice (as the first press was only a short press)...
nothing weird about that - perfectly normal...the potentiometer has NOTHING to do with that what-so-ever.

I have a exact same problem. I took it to the dealership to have it fixed, but it worked fine so I couldn't show it to them.
Hoping to hear if you are any luck fixing this problem.

I had the car in for service on the trunk closer problem last week. It looks like they ran diagnostics using SDS and got some codes back 9500, 9502 which made the tech replace the trunk control unit. The unit was reprogrammed using SDS. So far it has worked as expected. I don't know the partnumber for the control unit.
Does anyone know what the codes mean?

Hmm, I thought this was normal Mercedes stuff. Sometimes I only have to press once, sometimes I have to press twice. If I need to push twice, it makes the normal "thunk" sound on the first push, but the trunklid stays put. Second push, the lid closes.
I've never really found anything specific as to when it needs two pushes, but if it fails to happen for your SA, I bet you're pushing the button right after you opened the trunk and not waiting for a few minutes.

There seems to be no pattern. Sometimes I push once (it always whirrs) and walk away only to look back and find the trunk still open. It is never up for more than a few seconds. I open the trunk, grab my laptop, and push the button.

1987 Mercedes 300 SDL
Trunk Closer
I see that this is an option on the new Bluetec E320, and was wondering how everyone likes it? Is it worth the purchase. I haven't drove any of the newer models, the only MB car I have owned is the '87 300 SDL, which was bought brand new and has 388,000 miles on it. So all of the new features and options are totally new to me.

Same problem
I've been to my dealer 3 times already; first time they changed the trunk switch, and the last time they changed an electronic control unit. I'm still having the problem (pushing the switch more than once), and at times the trunk 'refuses' to shut and I have to force it down. This is an incredibly aggrevating problem.
I've call MBUSA about it to complain, and tomorrow I'll have to go back in again for the 4th time to have it looked at (and a total of six days with the dealership.) My car is only 1.5 months old (E350 2008) - I wish I had known this as I would not have gotten this option.
Can such an issue be cited under the California Lemon Law?

Thank you for that advise. I will call CAC tomorrow morning and request this of them. Hopefully this will all go well - I am tired of wasting all the time and energy over this. When I bought the car I expected everything would be Q&A tested and working.

I have an 08 E550 and I love the option.
Maybe out of 100 open/closes it has done it two or three times. I hear it start to bring the trunk down but it doesn't. I just hit the button again and it works.
I think its just one of those things. If its happening more often then that, then of course I'd take it to get checked.
I love the feature. It sounds like some of you, like Saffron, are having it happen A LOT??

mspaul, it is an option, actually on all W211 model versions (at least in Europe).

They're keeping my car for 2 days! They say that they cannot find anything wrong with the mechanism and they said that there are no error codes coming up. At least they are trying - let's see where this all goes. More to follow...
