VW Golf, Tiguan & Audi A3, A4, Q5 1.8/2.0 TSI Water Pump Assembly 06L121111

Product overview

This water pump assembly is a replacement part for Volkswagen Group 1.8 and 2.0 litre turbocharged petrol engines, referenced to OE number 06L 121 111 (the part listing also cites 06L 121 111 H). It circulates coolant through the engine, and common signs of failure include coolant leaks, overheating warnings and a sweet smell from the engine bay.
