Why isn't my Audi A7's engine starting?

I just bought a used Audi A7 and recently, the engine has been having trouble starting. It takes multiple attempts to start the car and sometimes it doesn't start at all. What could be causing this issue?

This could be due to a weak battery or a faulty starter motor. I recommend getting your battery checked and if necessary, replaced by a professional mechanic.

Another possible cause could be a faulty ignition switch. If your car's lights and accessories turn on, but the engine doesn't start, it could be a sign of a faulty ignition switch. It's best to take your car to a mechanic to get it checked out.
