clk cabrio window issues

[donv]

hi guys,

firstly i would like to wish you all a happy and prosperous new year

any way problems started on hogmany i was driving my car (clk cabrio w208) all happy i then went to put the pasasenger side window down there was no problem but when i went to raise the window with the one touch facility which has worked for the past year the window went up but then came down about an inch when reading through the manual it say's that if there is something obstructing the window it will come down but i have checked and made sure that all is correct now i know there is a way of resetting the window but dont know how any help would be appreciated

thanks in advance guys

Could be one of the stops is broken or gone out of adjustment. I had an issue with one of the rear windows on my wife's CLK cab and found the botton stop had broken. It's not too bad a job to pull out the rear seats and side panels to have a look and fix. Worst job is getting off the clips that hold the wind deflector. Just be patient and make sure you use something to protect the panel when levering.

max.

To reset the window.

Press down switch and when it reaches the bottom - Hold for 5 seconds.

Then press up switch and when it reaches the top - Hold for 5 seconds till it clicks(if your lucky).

Job done unless the stop is broken as previously suggested.

I also have this problem - intermittently - on my car. It doesn't affect the rear windows, but the front ones (either side) are sometimes affected by this problem. I have tried the reset procedure - no effect. The strange thing is that the problem just goes away, sometimes doesn't come back for months. A broken stop (or one needing adjustment) would be unlikely to have this effect.
Sometimes opening and shutting the doors helps. But not always.
If you find the answer - let me know. If at least two of us are affected, then it is likely that a lot more owners are as well!

This reply is for CLK FRONT windows only.

The problem posted above was resolved with a software/firmware upgrade.

For owners clever enough to get the upgrade whilst under warrenty great.

For owners that didn't, there are now 2 problems.

1) Dealers IF THEY WILL DO IT, charge for 'flashing' the ECU with the new version of the software.

2) Most of them claim they know nothing of the upgrade and even then they don't know how to go about flashing the ECU, or claim they dont have the software anymore. They hate doing this.

Sounds ridiculous doesn't it?

But on point 2 if you think about it, it is like being asked to reformat a hard drive on a PC, re-install and maybe test the OS and all the apps on it, to fix a minor problem.

Any new issues with the car with anything that is controlled by the ECU, the onus will then be on the dealer to discount that is not the new software that is broken, their view is better not to open that pandora's box...

If you do find a friendly dealer that does do this sort of thing (for a reasonable price) on early W208s then let me know, I'm not interested in defended the above POV - I would rather trot along and get upgraded!!!

Another reason why I would like to get upgraded is not because of the windows, I can live with that, but later software partly fixes another bug which tells the ECU to run the engine lean when it is warming up. Even then the new s'ware sometimes doesn't fix the problem entirely as entire ECUs need to be swapped out to totally fix it. If you're wondering what i'm talking about, sometimes there's a lumpy idle when the engine is warming up - and no I'm not talking about the MAF either...

The early £38K CLK is such a labour of love.

Hope this helps

Sashaaaaa

are you guys sure its nothing as simple as a dirty window runner? the increased friction may make the window think there is somthing in the way and stop/back down? mine do it occasionally (on the CL) - but it is 8/9 years old and has done 162,000 miles

i had a granada (iirc) that did this - but if i went from the bottom to the top it was ok - only happend if i went from half way (or whatever) to top. Eventually found that it was the motor mountings were slightly loose (rivets ) - new pop rivets installed, no problem. i think it was that the motor moved slightly, causing a sudden but slight increase in force, which the pooter thought was an obstruction.

 

[Paul Grainger]

I am certain that it is a software issue on my car. Sasha comments that the front windows only are affected - these are the exact symptoms that my car shows.

I will mention it to my stealer on the next service - see what he says. In the past it has been a minor irritation, but in some circumstances it could be an issue.

PS - My car doesn't have a lumpy idle when warming up (not that I have noticed anyway). Does the lumpy idle problem apply to all models? (Mine's a 320)

[sasha]

Lumpy idle doesn't always happen and it is NOT the natural lumpy idle sometimes attributed to the engine being a v6.

I cannot find the original post in any forum, basically i downloaded a document with all service bulletins for all mercs. In THAT document it listed, replace ECU for CLK if lumpy idle as the ECU is faulty (in conjunction with software and runs the engine lean in specific circumstances). I don't think running the engine lean for short periods is the end of the world? But like all complex finely tuned machinery I'm sure it doesn't do the engine any good.

Maybe someone else has the document or knows where it is?

This document holds the truth.

Errr.... I didn't know there was a one touch window raise facility!!! Do I have to enable it somehow? because mine only works auto down, manual raise! (ie: keep finger on the button)

maybe pre-facelift ones can be updated or something then

Just to confuse matters, mine are auto up/down. Pre-facelift, 99 model.

Try these:
You should open each window in turn by pressing the switch half-way until the window is fully open. Then close it the same way, but when it is fully closed, press it all the way for 5 seconds. One-touch should then work.

There is another way, by holding your key to the door and pressing the unlock button until the windows are all the way down and then pressing the lock button until they are closed.

yours is a coupe not a convertable, so its different i think....

 

[novaya_zemla]

I'll give that a go tomorrow.... My car is a 98 'S' Convertible.
