How can I solve a misfiring issue in my Audi A4?

I have recently been experiencing a misfiring issue in my Audi A4. The engine starts to shake and the check engine light turns on. What could be causing this issue and how can I fix it?

It is likely that the issue is caused by a faulty ignition coil. This can be a common problem in Audi A4s. I would recommend getting your car diagnosed by a professional mechanic to confirm the issue. If it is a faulty ignition coil, it should be replaced as soon as possible to avoid further damage to your engine.
