Mistery window, lifts up 7minutes after close door
Please, help
My 2008 cls350 had an issue with the passenger side window regulator failure. So, replaced the regulator and find out the window does not lifts up after close the door. the shop dissemble and assemble several times but no difference. Then I leave it for around 7minutes, it lifts up.
After all, the window lifts up after 7minutes when the door closes. The window drops little when the door open.
Anyone can help me on this ?????

1-- Start by scanning the car for faulty modules.
2-- Next have a look inside your door control module for solderless evidence...
3-- Gather wiring diagram and tools...
With this "Delayed CAN" condition beware of battery drain while parked... use a CTEK float charger.

delayed windows.... LOL 🙂
You have an extreme case of "delayed CAN-B response" very common.
1-- Start by scanning the car for faulty modules.
2-- Next have a look inside your door control module for solderless evidence...
3-- Gather wiring diagram and tools...
With this "Delayed CAN" condition beware of battery drain while parked... use a CTEK float charger.

Your car window controllers suffer extreme delays caused by poor connections of solderless pins disrupting your CAN-B transfers.... standard fare.
1-- SCAN YOUR CAR:
- Power up the car with ignition
- Plug your favorite MB scanner in OBDII DLC under the dashboard. Use an Autel or iCarsoft scanner you can trust not to waste your time with.
- This will retrieve a list of live fault codes from ALL computer modules.
2-- DOOR CONTROL MODULES :
- This is where fixes will be made inside the simple electronic door controller aka. "DCU".
- This module control everything electrical within the door: window, mirror, buttons.
- It just needs a quick 5mn soldering to work bettter than new.
3-- SCHEMATICS AND SOFTWARE TOOLS:
- You can buy schematics from many sources including from forum sponsor, the legendary @BenzNinja provider of remote services and rentals gear.
4-- Slow... 1mn TEST :
You want to know about your door health ...
- wind the window up/down
- compare with opposite side
- activate both windows at once
- Now start engine to get 14.5V
- and then repeat above tests.
> You have just exercised your car and witnessed its performance. You can appreciate that fixing a door will give you an increase of 30% in window speed. ⚡
5 > CAUSE... NOT THE SPEED
The fact is the windows speed is a sort of mirror for the health of the door DCU Module.
When it has poor connection it's sick like COVID. It works within a network of modules named CAN-B.
One module being deteriorated can bring DATA traffic to a crawl.
That is exactly what's going on now, the cause of your car delayed response.
6 > REFERED PAIN:
Another module may be screwing with that door DCU... the other side DCU's or a Star Solderless Keyless <<------ MAKE THIS YOUR NEXT BLESSING FOR MB -- Then disable the engine killer by unplugging low oil pump solenoid for full VVT 1500.RPM torque... soon added to my signature link.
Make your MB great again.

Thanks again, but I still can not get your explanations clearly. Would I need to do some soldering works? Means there would be some connection issues with DCU and other sockets? Your advise is up to 2, right ? From 3 are additional advises, right ?

door control module
driver window central control module
Buy yourself a $30 temperature-controlled soldering iron for this basic entry-level job - If you have time to learn: youtube is your friend.
Nice & easy
