Audi coolant reservoir (OEM 8D0121403L) — a used genuine tank removed from a donor vehicle. This expansion bottle also replaces 8D0121403J, 8D0121403F, and 8D0121403M. It stores coolant and allows thermal expansion; over time, the plastic can crack at the seams or the level sensor fails, leading to low-coolant warnings. Fits a range of Audi and Volkswagen models, including those with EA888 1.8T, 2.0 TDI, 2.7T, 2.8L, and 4.2L V8 engines (naturally aspirated and turbocharged).
