The 2024 Audi A4 continues to deliver premium sport sedan excellence with its refined 2.0L TFSI engine. When a P0304 code appears indicating a cylinder 4 misfire, prompt attention maintains the driving dynamics this German sedan provides.
Understanding P0304 in Your A4
The A4's 2.0L TFSI turbocharged engine combines performance with efficiency. Cylinder 4 sits at the rear of the inline-4 engine, closest to the firewall. The engine control module monitors each combustion event through crankshaft position analysis.
New Model Considerations
Misfires on new 2024 models are uncommon and typically indicate manufacturing defects covered under warranty. The proven TFSI platform has established reliability, and component failures on new vehicles are exceptions.
Diagnostic Steps
Access the cylinder 4 ignition coil at the engine's rear. Inspect for any obvious defects. Check spark plug condition. Verify boost system integrity. Ensure all software updates have been applied.
Resolution Path
Warranty coverage applies to 2024 models. Have your Audi dealer diagnose using factory equipment. Component failures causing P0304 should be covered.
