BMW Water Pump - Pierburg 11515A05704

Product Information

This aftermarket electric water pump is a direct replacement for your BMW's factory pump. Unlike traditional belt-driven pumps, this version is electrically powered and mounted externally, improving efficiency and reducing mechanical strain on the engine. It's a known failure point on many turbocharged BMWs, often failing as early as 100,000 km (60,000 miles), making preventative replacement a smart decision.

Common applications include models like the 1 Series M, 135i, 335i, and others equipped with the N54 or N55 engines.

Engine Water Pump Function:
The water pump ensures continuous coolant circulation through the engine and radiator. If it fails, overheating can quickly occur, risking engine damage.

Engine Water Pump Failure Symptoms:

• Coolant leaking from the weep hole
• Excessive play or wobble at the pulley shaft
• Squeaking or whining noise at idle
• Engine overheating or fluctuating temperature
• Low coolant warning on the dashboard
