How do I fix a malfunctioning door handle on my Audi A2?

Recently, my Audi A2's door handle has been becoming increasingly difficult to open. I have tried lubricating it and checking for any loose screws, but the problem persists. Any advice on how to fix this issue?

First, check for any debris or buildup around the door handle. Sometimes this can cause issues with opening and closing. If that doesn't work, try using a lubricant specifically designed for door handles. If the problem still persists, it may be a sign of a more serious issue and you should bring it to a mechanic for further inspection.
