The Audi TFSI and Volkswagen TSI engines, found in popular models from Volkswagen, Audi, Skoda, and Porsche, are known for their exceptional performance. However, one common issue owners face is the water pump and thermostat assembly, which is located beneath the intake manifold. Typically, this component needs replacement every 50,000 - 80,000 km (or every 5 to 10 years) due to leaks. To ensure your engine runs smoothly, efficiently and without leaks, we recommend a replacement from INA. This part is the original equipment manufacturer (OEM) part fitted by the Volkswagen-Audi Group, ensuring the highest quality and compatibility with your vehicle. We sell this part with the INA/VW logos removed, offering it as an “aftermarket” part with a significant cost saving. This part is not ‘perfect’, but it’s the best we have known of, and it will keep your engine running leak-free at the right temperature for the longest.
