This used Audi 04E121042L coolant pump / water pump is a genuine OEM part, removed from a donor vehicle. It also replaces OEM numbers 04E121600AQ, 04E121600D, and 04E121600AG. Found in 1.4L turbocharged gas and plug-in hybrid engines (EA211 family), this pump circulates coolant to prevent overheating. A failing water pump often causes coolant leaks, engine temperature warnings, or a whining noise from the pulley bearing. Give your Audi A3 or A3 Sportback e-tron a reliable factory pump at a fraction of dealer cost.
