So... This is a strange one, somehow the one touch function on the driver side window has stopped working after a remote coding session trying to fix the B&O lights... Long story short, here're the things I've done trying to fix it:

1) The standard holding the button all the way up and down several times didn't work.
2) Replaced door module but same issue so it might not be coding related anymore?
3) Replaced window motor, same issue.
4) Coding the door module from RHD to LHD, this actually made all 4 windows' one touch working again but in LHD's order, so this ruling out the button itself is bad? Same thing with the new door module, driver side doesn't work with RHD code, but works when coded to LHD..

Totally puzzled and out of idea, anyone care to chime in?

make sure the door module is the correct one for your vehicles design database and is parameterised as such.
 
What did you do during the remote coding session?

Supposedly, the guy was just checking the door modules to see if the parameters for the ambient lighting is there and didn't do anything else. Afterwards, both windows' one touch function on driver and passenger side ceased to work, the passenger side reset after a few rolling up and down holding onto the button, but the driver side never reset.

I switched the driver door module with another car with the same spec for testing, problem persisted leading me to think it's not coding or parameters, and what's more strange is coding both modules to LHD made the one touch function working again but of course with the sides switched... I'm out of ideas...

do you know 100% that the door module you have in the vehicle is correct and that its been parameterised correctly? If not then that's where I would start.

He worked on both front modules at the same time and both modules are originals that came with the car, he sweared that he didn’t change anything else besides loading the ambient parameters...

Since the passenger side works, I assumed the parameters are correct? No idea what else could possible be the reason for just the driver side...

Reupload the parameters for the drivers side door. Upload all the necessary parameters and if you use VCP don't forget to do "erase all memory".

Afterwards put your original coding back from an old log.

This is the problem when working with remote coders, you never really know what's going on or indeed 100% whats been done. Would suggest a local session, or indeed another remote session, with someone you trust and who communicates whats been done and why. Stock modules with SVM coding should return factory features.
 
Thanks guys, but still find it strange if it’s indeed wrong parameters, switching with a known working module still the same result, that’s what really puzzling me...

That's really strange, especially because you've tried with a known working module and even replaced the window motor with no success. Did you try to test in another car the module that was remotely coded? I know strange things happen. A short time ago I couldn't make the one touch function to work in one of my windows. Tried the hold button up and down method several times but no success. It only worked when I tried to do it with the door open. Then the one touch started to work after the first try.
 
while part numbers may indeed match parameters, which is / are very different to coding and adaptation, can be very very different depending on a vehicles specification / equipment level. Without knowing the full steps completed its hard to guess whats happened or indeed whats not happening. If this was my session I would:

-Make sure correct part number module is installed in vehicle, including firmware level
-run replace control module test plan and complete
-run SVM test plan in order to be sure all is as needed with door modules and indeed central electrics
-disconnect door module in order for it to "hard" power down
-reconnect and perform basic settings on windows
-let vehicle / CAN network shutdown
-power on and then test
 
Thanks guys, the part number and firmware level is correct, and all the other tests are done... BUT... Just thought of something, the remote session and the test module are from LHD country (China), could the parameters be different for LHD vs RHD besides just the long coding? That would also explains why auto functions work when I code it to LHD...

You could try to upload the parameters of a passenger door. But it should be the same, the coding decides if its LHD or RHD.

The correct parameters for your vehicle should be uploaded to your module during the SVM / replacement procedure.

I've understood you've tested by replacing your modules with working modules from another car with same specs and still the one touch function didn't work, so I think it completely rules out the possibility that something wrong with your original modules' coding/parameters could be still the cause of the problem, right?
Maybe you could check other possibilities like low battery, faulty electrical connections at the battery, door to car body connector, door module connectors, window regulator connector, etc, anything that could cause an electrical current loss that might be interfering with the module's ability to detect the current increase that occurs when the regulator motor reaches the upper/lower limits. Did you test the anti-pinch feature to sse if it still works? If there's an obstacle in the way of the windows when it's closing, the motor should stop and revert immediately leaving the window fully open.
