Advice:

The Audi A8 (D2) uses two heater pipes (4D0819159), and we recommend replacing both at the same time to save time and money.

About this part:

The Audi A8 (D2) was Volkswagen’s first full-size luxury sedan, designed to compete directly with the BMW 7 Series and Mercedes-Benz S-Class. It offered a perfect balance between Munich’s sporty dynamics and Stuttgart’s superior comfort, alongside innovative solutions for improved performance, efficiency, and durability.

One of its standout features was the Audi Space Frame — a lightweight aluminum chassis that made the A8 more corrosion-resistant and lighter than its competitors. However, while the body was exceptionally durable, the cooling system relied heavily on plastic and lower-grade steel components, which were prone to wear and failure over time.

A common issue lies with the heater pipes (4D0819159). These plastic pipes, reinforced with steel, are prone to coolant leaks, leading to system airlocks, heater damage, and even engine overheating.

The ultimate solution is the stainless steel heater pipe, designed for durability and longevity. Built from premium stainless steel, this part is resistant to corrosion, extreme temperatures, and vibration, offering a permanent fix for this issue. This part ensures your cooling system and heater are protected for years to come.
