• PRESSURIZED 1.4 L CONFIGURATION:The included cap has a listed maximum pressure rating of 140 ±15 kPa. The 1.4 L capacity is measured at the MAX fill level rather than the brim, leaving the intended coolant expansion space. PP construction is rated from -30°C to 120°C for the stated operating environment. Confirm the original mounting points, hose connections and electrical configuration before installation.
• REPLACEMENT REFERENCES:Cross-references V10-4478, 8K0121403Q, 8K0121403T, 8K0121403D and 8K0121403G. Compare both the replacement number and physical connection layout because similar-looking Audi reservoirs may have different hose, mounting or electrical configurations.
• BUILT AROUND REAL REPLACEMENT NEEDS:Cracks, seam or hose-neck seepage, dried coolant residue, repeated coolant top-offs or a low-coolant warning may indicate deterioration of the original reservoir or its connections. BDFHYK treats the tank as part of a pressurized cooling system: cap rating, cap-neck sealing, hose connections, clamps, electrical insert seating, correct filling and bleeding all affect operation. Continued coolant loss or elevated engine temperature requires complete cooling-system diagnosis.
