How to fix a non-opening electric door on the passenger side of a Volkswagen Sharan after replacing the 12V battery

I thought the fix was so weird that I decided to write a blog post about it.

Have you ever wondered why the electric door on the passenger side of the Volkswagen Sharan won't open after you've fitted a new battery? Neither had I until last week when I picked up my car from the mechanic and noticed that the door button was blinking, and nothing happened when I pressed it. The closing mechanism was working fine after I, with quite some force, opened the door manually.

I asked the shop for help, but they were clueless and tried to diagnose the issue by connecting their iPad to the car's diagnostic port and running a series of tests with no luck. While they did that, I decided to do a quick search online and found a potential solution on a forum. The solution is to reset the automatic window setup on the door that won't open.

The solution

1. Using the window button on the door that won't open, open the window fully.
2. Release the button and press it again for 3 seconds.
3. Close the window fully.
4. Release the button and press it again for 3 seconds.

I did this once, and the blinking stopped, and the door opened when I pressed the door button. It was a weird fix, but it worked!

PS. I do like long blog post titles.
