Engine and performance problems with an Audi S8

Hello everyone, I'm having problems with my Audi S8, model year 2008, 5.2l gasoline engine, with a mileage of 130,000 km. When starting, it takes a long time to start, and after a short time either the EPC or the check engine light comes on. In addition, it jerks when accelerating and at idle. The car was in the garage for 3 weeks, before that I never had a problem. Does anyone have an idea what could be causing this? Thanks in advance for your answers. Best regards, Cihan.

Summary of the thread

An Audi S8 owner is experiencing prolonged starting times, EPC or check engine light activation, and jerking during acceleration and idling. These issues began after the car was in the garage for three weeks. Potential causes include a weak or discharged battery, which can affect starting and trigger warning lights. It is suggested to check the battery voltage and connections, and if the battery is fine, to scan for error codes to pinpoint specific problems.

Start by checking the battery voltage and connections, as a weak or discharged battery can cause starting issues and trigger warning lights. Ensure the battery terminals are clean and tightly connected. If the battery is fine, consider scanning for error codes to identify specific issues. Let me know how it goes or if you have further questions!
