How to diagnose engine problems in an Audi A4?

I have a 2015 Audi A4 and the engine light recently came on. I'm not sure what the problem could be. Any advice on how to diagnose engine problems in this model?

First, try checking the error codes with an OBD scanner. This will give you a better idea of what the problem could be. You can also check the spark plugs and ignition coils.

I had a similar issue with my A4 and it turned out to be a faulty oxygen sensor. It's important to get it fixed as soon as possible to prevent any further damage.

I would recommend taking your car to a certified mechanic for a thorough inspection. They have the expertise and tools to properly diagnose any engine problems in your Audi A4.
