Audi TT Quattro starts but cuts off after 2 minutes, won't stay running on Audi TT Quattro

Some Audi TT Quattro owners report experiencing issues where the vehicle starts but then cuts off shortly after, often failing to stay running. A common cause for this problem is a lack of fuel pressure, which can lead to stalling right after starting. Additionally, issues with fuel, air, and spark timing may contribute to this stalling behavior. Some owners have also encountered problems with a faulty immobilizer that fails to recognize the car key, resulting in the engine starting but dying immediately. Recommended troubleshooting steps include checking the immobilizer light in the cluster, experimenting with different key positions, and allowing the car to sit with the key in the ignition for a while before attempting to restart. Addressing these potential causes is essential for resolving the issue effectively.
