Can I use a diesel engine in my Audi A4?

I'm wondering if I can switch out the gas engine in my Audi A4 for a diesel one. Is this possible and what are the implications?

Unfortunately, it is not recommended to switch out the gas engine for a diesel one in your Audi A4. While it may seem like a convenient solution, it can lead to potential damage to your car and may even void your warranty.

Yes, technically it is possible to swap out the gas engine for a diesel one in your Audi A4. However, this requires significant modifications to the engine and can be quite costly. It's best to stick with the engine that your car was designed for.
