Audi A4 2010 - P0016 Fault: Car Cranks but Won't Start After Air Intake Disconnection
Audi A4 2010 with 2.0T engine. Last night, I accidentally left the air intake hose disconnected near the air filter box while working on it. I then drove approximately 5 miles to the store to refill fuel. Upon returning, the vehicle exhibited rough idling. After shutting it off, I attempted to restart it but the car only cranks — it does not start. Previously, I had detected a fault code P0016, which I was able to clear easily. The vehicle was running normally before this incident. Any insights or troubleshooting steps for this issue would be greatly appreciated.
Check the trouble codes in this forum as they can indicate root causes. P0016 is typically related to camshaft position sensor or timing chain issues, not directly caused by air intake disconnection — unless there were also vacuum lines or electrical wires disconnected during the process.
