Why is my Volkswagen Passat experiencing engine issues?

I've had my Volkswagen Passat for a few years now and I've recently been experiencing some engine issues. It seems like it's running rough and there's a slight knocking sound. Does anyone have any advice on what could be causing this?

Hi Emma, it's possible that there could be a problem with your ignition coil. I had a similar issue with my Passat and that was the culprit.

It could also be an issue with your fuel injectors. Make sure they are clean and functioning properly.

I've also experienced engine issues with my Passat and it turned out to be a faulty timing belt. Definitely worth checking into.
