Description

Overview

An electric water pump for Volkswagen Group 1.4 litre TSI and TFSI petrol engines, referenced to OE number 03C 121 004 J, with 03C 121 004 L also quoted. These pumps support coolant circulation, particularly after the engine is switched off or under high load, helping to protect the turbocharger and maintain stable temperatures.

When an electric pump fails, symptoms can include coolant temperature warnings, fault codes, overheating after short trips or a buzzing noise from the pump area. Replacing it helps prevent heat-related damage to the turbo and engine.

Vehicle compatibility

Listing attributes list the Audi A1 (8X1, 8XK), Seat Ibiza IV ST, Volkswagen Polo (6R, 6C) and Tiguan (5N) with 1.4 litre turbo petrol engines from about 2007. The automated table contains around 200 entries, including diesel and other petrol engines across Golf, Passat, Touran, Caddy, Sharan and Audi A3, which may not all be correct. Confirm by OE number or engine code before ordering.

Key features

  • Electrically driven coolant pump
  • Suits 1.4 TSI, 1.4 TFSI and 1.4 GTI engines listed

Allow the engine to cool fully before starting. Disconnect the battery, clamp the coolant hoses to minimise loss, and transfer the mounting bracket if required. Refill with the specified coolant and bleed the system thoroughly. Workshop fitting and a diagnostic check to clear fault codes are recommended.

Fitment checks before ordering

Electric pumps with similar appearance can have different flow rates and plugs. Check the number on your existing pump and verify by engine code or VIN before purchase.
