W204 Coupe Electric Seat & Power Window Issues

2 posts in this topic

Hi , I’m having slight problem with my electric sear on passenger side, it doesn’t allow me to fully adjust the seat upright. My passenger side window I have to hold the button in order for the window to be fully close, used to be click and auto slide up. 


Anyone able to advice the issues and how to rectify it. 

Thank you very much in advance.

If this is from C&C, go and have them reset the seat ECU. A 10min job. 

If you have not upgraded the software on the ECU yet, also ask for a software upgrade, this could fix the issue once and for all. Else, every 3 months, you have to reset your seat ECU.
