Electrical fault and cylinder misfire in Audi Q2

Start by checking the ignition coils and spark plugs for any signs of wear or damage, as these are common causes of misfires. Ensure they are properly connected and functioning. If the issue persists, it might be related to the engine control unit (ECU) software, which may require a diagnostic scan at a dealership or a qualified mechanic. The 'dynamic_break_1' message could be related to the vehicle's braking system, which is safety-critical. I recommend having a professional inspect it as soon as possible. Let me know how it goes or if you have any further questions!
