A 2017 Volkswagen Passat is now 9 years old, so an average example has covered around 121,500 miles. A late-run car · the most reliable part of the generation, but higher-mileage wear items are usually the deciding factor. Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2017 car has usually reached the mileage where they appear.

The 2017 Volkswagen Passat is 9 years old, so an average example has covered roughly 121,500 miles. At that mileage 7 of the documented faults are already due, so check those first.
Documented onset mileage is at or below the ~122k miles an average 2017 car has covered.
1.8T/2.0T water-pump, timing-chain tensioner and carbon build-up.
DSG/automatic jerky shifts if service neglected.
Control-arm bushing and strut wear.
Heater matrix blockage caused by a ruptured silica silicate bag inside the coolant expansion tank.
Dual Mass Flywheel (DMF) failure resulting in metallic rattling and harsh vibrations through the drivetrain.
Electronic Parking Brake (EPB) motor failure or sticking rear calipers causing binding rear wheels.
EGR cooler internal leaks leading to unexplained coolant loss, rough idling, and sweet-smelling exhaust.
Age, electronics and build-related issues that are not mileage-driven.
Infotainment, sensor and window faults.

Early 1.8/2.0T engines can suffer chain-tensioner and water-pump issues.
Timing-chain noise, coolant leaks, transmission history and electronics.
The Passat GTE requires specialised servicing. The high-voltage battery cooling system must be inspected regularly, and the DSG gearbox requires fluid and filter changes every 40,000 miles. Ensure the charging cable is present and test the flap mechanism in the front grille, as the release catch frequently seizes.
For the EA288 2.0 TDI engine common in this era, Volkswagen UK recommends replacing the cambelt and water pump every 140,000 miles or five years, whichever comes first. Dealers should verify this history, as a snapped belt will cause catastrophic internal engine damage.
Euro 6 compliant diesel Passats use AdBlue to reduce emissions. The system is prone to injector blockages and NOx sensor failures, which trigger a dashboard countdown that eventually prevents the engine from starting. Always check for AdBlue warning lights and ensure the tank contains uncontaminated fluid.
