This genuine OEM turbo coolant line / pipe / tube set, part number 04E122157AT, is a used component from a salvaged Audi. It also replaces 04E121497Q. Designed for the 1.4L plug-in hybrid turbo engine in the Audi A3 Sportback e-tron, this set carries coolant to and from the turbocharger to prevent overheating. A failing line may cause coolant leaks, leading to low fluid levels or overheating—replace it promptly to maintain turbo performance.
