Used OEM Audi Coolant Reservoir Mount—part number 4G0121214AF—also superseding 4G0121214N, 4G0121214AG, and 4G0121214H. This bracket secures the coolant expansion tank on A6, A7, S6, and S7 models with 1.8T, 2.0T, 3.0 TDI, 3.0 supercharged, or 4.0T engines. When the mount cracks, the reservoir can shift or vibrate, stressing hoses and potentially causing leaks. A direct bolt-on replacement that restores proper reservoir support.
