P0480 on Audi
Cooling Fan 1 Control Circuit
P0480 on Audi vehicles indicates cooling fan 1 control circuit. Au7o has documented this code across 1 Audi model — most commonly on A4. P0480 indicates a fault in the engine control module's circuit that operates cooling fan 1 (or the fan relay it drives). The computer detected an open, short, or out-of-range condition in the fan control output. Because the cooling fan helps prevent the engine from overheating — especially at idle, low speeds, or with the A/C on — a fan that won't run can lead to high coolant temperatures. It is worth addressing fairly promptly to avoid overheating, particularly in hot weather or stop-and-go traffic. Typical repair costs on Audi range from $150 to $500, depending on the specific model and root cause.
Common Causes of P0480
- •Faulty cooling fan relay
- •Failed cooling fan motor
- •Wiring damage, shorts, or corroded connectors in the fan circuit
- •Blown fuse or fusible link for the fan
- •Poor ground for the fan motor or relay
- •Faulty fan control module (where used)
- •PCM driver circuit fault (less common)
