Well, I did some experimenting today and I got my sunroof to work in tunnel mode. Hopefully you guys will not have as much of a problem getting your dealer to turn this on, because it is something that should be enabled anyway.

Here are the instructions for the DAS computer that they have at the dealer:

Go to Control Units --> Body --> Overhead Control Panel(OCP) --> Control Unit Adaptations --> Read coding & change if necessary --> Modular Roof

On the modular roof screen, set "Automatic closing function" to "Active" and that should do it.

Good Luck.

Thanks, Matt!! I've always had a feeling that it can be programmed. Nice to know that it is indeed so. Shall request this done on my next visit to the dealer.... It actually has been a while... Even forgot my service writer's name

young

sweet! nice job. now i have to think of a reason to visit the dealer to get this programmed...

Matt230K

I think it's reason enough to make a special trip. Ok, maybe not!!

But it's still a nice feature. I've never used it except to try it out, and I don't go through tunnels that often. But it works great just to close everything up when you are parking the car. Especially since there is no one-touch close for the roof. It doesn't matter as much anymore because this works like a one-touch close.

Awesome!!!

Thanks Matt!

I've never heard of tunnel mode, what is it?

Does this enable the sunroof closing in tunnel mode on the C230 Coupe?

darkfact

duuuuuh!

Silver_Lana

Yes. The reason for the aforementioned experiments is that the C coupe was the only C Class that didnt have the tunnel mode feature.

cliffybabe:
Tunnel mode is pushing and holding the recirculate button on your air conditioning unit and it will automatically close all windows and the sunroof -if you have one.
This was put into place as a convenient feature since the air in tunnels is usually stale or polluted from accumulating exhaust fumes. Once youre out of the tunnel, press and hold again and it will return your windows and sunroof right back to where they were before you went into tunnel mode.

cliffybabe

Thanks i'll try that later, see if mine works

cliffybabe

Well I tried it and it worked, wicked trick

Cheers

Tried it last night... Windows worked and returned to their original positions, but not the roof. Went to the dealership today, and $25.00 later, the roof now works. This should have been enabled on the '02s, but c'est l'avie. Also had the "No Phone" message disabled at the same time. Tired of the car reminding me that I don't have a ridiculously expensive option installed.

TTFN!:p

Matt230K

Well, I'm glad my research has helped some people, but it's just too bad that dealers are charging people for this. I think it's something that should be checked before the car is sold and make sure it works first. But I doubt many dealers know about this. And $25 is probably pretty cheap. I'm sure others will have to pay more, if the dealer is willing to do it at all.

Silver_Lana

I agree. You shouldnt have to pay for a feature that already exists on your car. When i had the dealer set the car to Xenon-Present after i had my Bi-Xenons installed, it was at no charge including the complimentary carwash as well as breakfast on them.
Kudos to Ray Catena in NJ.

Silver_Lana

Wicked indeed!
I am glad i could be of help. I accept payment in GBP or Euros.

Awesome! I'll have the dealer fix this.

Now if this can be done, doesn't it follow to reason that the passenger mirror should be able to be enabled to "look down at the curb" when the car is placed in reverse (when the passenger mirror button is left in it's pressed position)?

I have to park in a very weirdly designed parking lot (all curves) and this would help save the rims if it could be activated in the coupe. I think this already works in the sedans and wagons (2003's), but not on the 2002's.

I'm getting more and more happy that I bought this car. I have a stack of papers that the dealer must address when the car is on the computer, but I don't mind...

SLK2C230K

My dealer is generally very good to me. I am able to take the car in after hours and play. I am currently in the process of installing a MB OEM BOSE system into my coupe... I am waiting for a MB wiring harness and will let everyone know how I make out. I got the BOSE from someone who had removed it from his coupe and went with an aftermarket system. I am also wanting to install a BI-Xenon upgrade in the coupe (at least HID H7 Update) and the dealer is willing to put the coupe on the star cart afterhours (read... no charge), so a small charge here and there when I use the shop during business hours is not too bad. The MB techs are happy when I show up with stuff from forums, albeit surprised at the accuracy of the information. Both, the roof and no phone mods were completed in under 2 minutes once connected to the DAS Star Cart. Because they were charging for the service, they felt compelled to check their work, as they should, hence the charge.


MATT.... thanks for the info... all these little mods help me to enjoy my car that much more and miss my namesake a little less..... naw... I miss my SLK

Cheers!

The look down at curb feature is part of the C1 package. I doubt that it could be enabled separately.

steffen

My strategy was to show them the manual at the next visit and tell them the tunnel mode doesn't work as advertised. Doesn't the manual say the roof closes as well in tunnel mode?

In that case, reprogramming the computer should be considered warranty work.

alright! just got back from the dealer and had this "feature" turned on. thanks again, matt.

-
btw, bob, the technician said there were 2 settings. the one as described above and a "memory" setting for the panoroof. he turned both on for me.

Matt230K

Yeah, I think that is the setting that I tried first, but it didn't make the roof work. So I just turned it back off and did the other one and that worked. If you can figure out what that memory setting does, I might have to turn it on. There has to be something different that it does.

young

bob said it was for the sunroof position memory.

matt, w/out that on, you're panoroof reverts to whatever position that it was on? (not fully open).

i don't know what it's for if not that.

E55AMG99

Does anyone know if this feature is available on other cars?

Lynn

It is on all currently sold MB cars, except the SLK.

E55AMG99

I'm guessing MY 2003 and up?
