Product Description
Water Pump 06H121026CN For Audi A4L / Q5 / EA888 2.0 TFSI — OEM Integrated Thermostat & Housing Assembly
Product Overview
The Engine Water Pump with OEM reference number 06H121026CN is a verified direct-fit replacement for a wide range of Audi and Volkswagen vehicles equipped with the 1.8L and 2.0L TFSI/TSI engines from the EA888 Gen 2 engine family. This integrated assembly is a critical component of the engine's cooling system, responsible for circulating coolant through the engine block, cylinder head, and radiator to maintain optimal operating temperatures.
The 06H121026CN water pump is a complete assembly that includes the water pump, thermostat, and housing in one unit. This integrated design simplifies installation and ensures proper sealing between components. A failing water pump can lead to coolant leaks, engine overheating, reduced performance, and potentially severe engine damage.
Critical Technical Note: The original equipment water pumps on EA888 engines were manufactured with plastic impellers and housings that are vulnerable to failure, especially when exposed to oil leaks from the front of the engine block. This OEM-grade replacement pump addresses this concern with improved materials and construction for enhanced durability and long-term reliability.

⚠️ Important Compatibility Notes:
  • This water pump is specifically designed for EA888 Gen 2 engines. For EA888 Gen 3 engines (2015+), a different water pump (06L121026H) may be required.
  • Always verify your vehicle's engine code and original part number before ordering. If you have a CBFA engine code, confirm fitment as some variants may require a different pump.
  • The 06H121026CN is a genuine OEM part from FAW-Volkswagen. It is the correct specification for Chinese-market Audi A4L and Q5 models.
Common Failure Symptoms
Symptom Description
Coolant leaks Visible coolant puddles under the vehicle or around the water pump area
Engine overheating Temperature gauge rising above normal operating range
Low coolant warning Dashboard warning light indicating low coolant level
Thermostat failure Engine takes too long to warm up or runs too hot
Coolant temperature sensor malfunction Incorrect temperature readings on dashboard
Steam from engine bay Coolant boiling or leaking onto hot engine components
⚠️ Ignoring a failing water pump can lead to:
  • Severe engine damage from overheating
  • Warped cylinder head or blown head gasket
  • Premature failure of other cooling system components
  • Costly engine repairs or complete engine replacement
Manufacturer Note: Audi has issued a warranty extension for the engine water pump on certain 2.0L EA888 vehicles, covering repair or replacement for up to 10 years or 100,000 miles. Check your VIN with an authorized Audi dealer to determine eligibility.
