The 2014–2023 Passat B8 is a diesel family-car buy. Its /EA288 evo engines have version-specific gearboxes, including /DQ381/DQ500 units. Check gearbox servicing, cooling and emissions systems; CUAA versions add complexity.
This is an editorial score of your buying risk, not a measured failure percentage. The car’s condition, maintenance and which faults below apply determine this 79/100 assessment. Owner reports tell you what to check, not how often cars fail overall. Confidence is limited because figures for each engine are incomplete.
Typical lifespan: You can get high mileage from a sound, properly maintained car, but nobody can guarantee how much life remains. With a classic, the strength of the body and availability of parts matter more than the mileage reading. With a diesel, exhaust-cleaning or gearbox repairs may make the car uneconomical before the engine wears out.
This is a general assessment of this model and engine, not a guarantee of this individual car's condition.
cooling-system faults can cause loss or poor circulation. Do not assume the is responsible. Lower-frequency family-level risk; exact B8 fault rates are unavailable.
Soot can restrict (exhaust gas recirculation, which feeds some exhaust back into the engine) operation; a leaking cooler can lose internally. owners report trouble after emissions updates, but reports do not prove the update caused every failure.
Repeated short runs can prevent soot burn-off cleaning; accumulated ash eventually needs off-car cleaning or replacement. A pressure can mimic blockage. Do not buy a filter that has been removed or disabled as a repair.
(selective catalytic reduction, an exhaust-cleaning system)-equipped cars can develop , dosing, heater or tank/pump faults and a no-restart countdown. Not every early Euro 6 version has the same exhaust hardware.
Applies only to the fitted (VW’s automatic gearbox), not a manual. Wet- DSG needs the correct oil-service schedule for its gearbox code. Clutch, hydraulic or electronic faults can cause jerking or loss of drive; a full replacement costs more than a specialist repair.
Heavy, high-mileage cars wear and joints; broken coil springs may only be found on a lift. This is often mileage-related rather than an engine defect.
Owner accounts and buyer guides describe navigation, display or connectivity faults. Software updates may resolve some; replacement hardware is more expensive.
This risk comes from scheduled maintenance, not proof that every engine has a faulty belt. If the belt fails, it can badly damage your engine. Check the schedule for your (vehicle identification number). If there is no record of replacement, replace the belt kit rather than trust a handwritten sticker.

With a score of 79/100, this is a good buy if the checks below come back clean. You should buy based on records of the car’s condition, a start from completely cold, a long test drive and an independent inspection. You should choose a diesel only if your regular journeys let the engine and exhaust warm up fully.
Always check this car's actual condition and maintenance history — ideally with an independent inspection.
