What are common issues with the Audi A3 engine?

I'm currently considering purchasing an Audi A3, but I've heard some concerns about potential engine problems. What are some typical issues and how can they be addressed?

The most common issue with Audi A3 engines is oil consumption. Unfortunately, this is a known issue with some models, usually due to a faulty piston ring. To address this, regular oil checks and changes are essential.

Another common issue is the ignition coils failing. Symptoms include misfires, stalling, and a rough running engine. It's best to replace all ignition coils at the same time to prevent future problems.
