Help with window nudge operation

[machasm]

Hi All,
After various failed searches I have finally given in and decided to pose the question to this most knowledgeable forum (bum kissing complete)

On my friends 208 CLK55 I noticed that when he opens the doors the windows wind down a fraction. Also when he closes them that the windows then close up a fraction. What is this function called? (might help with future searches) and how do I get it to work on my CLK55?
thanks
Mac.

Have seen that on convertibles like the R129 SL, but if I remember correctly, Maff's CL500 did it as well, and that was a Coupe .... its to stop too much pressure building up inside the car / door seal and allows the door to close more easily ... soft/easy closure, I think its called ?

Is your car pre or post-facelift, compared to your friend's ? Otherwise, no idea how it is enabled / disabled if its not in the manual - not much help am I !! I'll shut up now !

**EDIT** actually, I don't think its called that at all .. that's the S-Class / CL auto door closing thing that sucks the doors closed so you don't have to slam them (my BMW tailgate has this too ) So not sure what the window nudging thing is called.

Thanks sym,
My friends CLK55 is exactly the same model and year so I think it should work on mine too.
It might prevent me having to close the door behind my kids all the time because they don't give it enough welly.
Still, would be even nicer if I didn't have to give it too much welly either.

P.S My model is the one in the sig.
Post facelift.

Mac, mine doesn't do this either although I was expecting it to as I'd noticed it happening on other CLK's when I was car-hunting. Assumed it was just on certain models and didn't give it any more thought but now I know it should be doing it it's going to bug me......

I had it on my Pug 406 Coupe. They claimed it was to enable the door glass to make a good seal. They didn't have a name for it either, IIRC.

I think they're called 'comfort windows', see this thread on the same subject:

Thanks Bill. It appears that there is some doubt as to the terminology even in the thread you mention. Nor does it give any explanation on how to resolve it.
Did a search on comfort windows and still doesn't bring up anything.
Anyone else got any ideas?

On the SL they're for a tight seal - you can't close the doors with the window in the 'full up' position.

Thats right. If the window/s didnt drop a couple of CMs when opening the doors they would pull the roof seal off (no window frames you see). Its just the same on SLKs.

On my CL its so the seal doesnt get trapped by the top edge of the glass.

Usually it doesnt work when it 'forgets' where it is. Do the windows still 'auto down' (ie press button hard, and they roll to the bottom?) I bet not..

So - to re-set.

1st, completely 'confuse' the system. open both doors, wind all 4 windows to halfway point. Go to fuse box. Pull fuse(s) for anything to do with windows. leave 5 mins.

Now - get in car. Close door. wind FRONT window to bottom. Press and hold down button for 5 seconds. release. Raise window to top., again press and hold for 5 seconds. Check it now auto ups and or at least downs.. (some dont auto up, almost all auto down and a 55 amg should be fully loaded)

Close front window to top. Repeat for REAR window. (wind to top etc). Repeat for other side.

edit - just checked WIS - only need to go 'up'

Thanks Guy,
My windows do auto up and down just fine so I tried the 'confuse' mthod anyway.Still doesn't work
Is there any way of knowing for sure if my car has the feature or not?

[guydewdney]

maybe its soft tops only?

 

[BTB 500]

The 1997 R129 SL range brochure says

When the doors are opened or closed, a new window-prompter system briefly lowers the side windows and then automatically returns them to their original position. This system ensures that there is always a tight fit between the windows and the soft top. Another benefit is that it makes it a little easier to open and close the doors.

"Window-prompter"?!

I have seen it working on my mates coupe.
Same year as well and same model!
Thanks again Guy.

A little easier? Mine won't close at all if they're all the way up!

 

[guydewdney]

ok - desparation..

wind windows to halfway. open doors. disconnect battery for half an hour. realize you dont have code for radio. panic. reconnect battery, re-try re-set procedure above. i have re-checked the wis - and thats all i can find.

phone your dealer? (hahhahahahha like they are going to know)

 

[Shude]

Could be a software option, maybe on yours it's turned off?

Mine neither, and the handbook says not to attempt it.

I only read that after the supplying dealership did the handover to me with no battery in the vehicle, which of course involved opening and closing the doors. The salesman did have to give them a good slam

 

[machasm]

I am beginning to think that this is more likely to be the case.
My friends CLK had the same problem until he took it into a stealer who 'reset it' for him.
What that actually means is anyone guess though. Could be that they switched the facility on via some new software/firmware.

Still looking though.

What about C240Sport's clk55 can you verify?

 

[C240Sport97]

Per PM to machasm:

Yes, mine (01 Y) has the 'feature' -- it's fantastic as it means you don't have to slam the door. This also featured on the old 3 series coupe I had.

When I was looking for my CLK, the MB salesman told me that the feature was 'added' to CLKs built after a certain date -- this may be why machasm's mate CLK has it and his doesn't. Don't know whether it's just software or if you need a bit of kit.
