The EA839 3.0T V6 vacuum-actuated water pump internal seal can fail, allowing coolant to leak into the vacuum-control system on 2019-2024 Audi S5 models. The first symptom is typically a coolant-level warning, followed by coolant residue on switching valve N649; it may also trigger P0299 turbo under-boost and 'Drivetrain Malfunction' warnings, creating a risk of sudden power loss while driving. Audi issued TSBs MC-10245526-0001 and MC-10172894-0001 acknowledging the coolant pump leak issue.
