Error code P027200 and jerking when accelerating

I have a problem with my VW Golf. When accelerating, especially above 120 km/h, the engine jerks noticeably. In addition, my vehicle displays the error code P027200. Does anyone have experience with these symptoms or can someone help me to solve these problems?

(Translated from German)

The error code P0272 indicates an issue with cylinder 4's fuel injector circuit. Start by checking the wiring and connectors for the injector on cylinder 4 for any signs of damage or loose connections. If everything looks fine, consider testing the injector itself for proper operation. Let me know how it goes or if you have any further questions!
