6.2/10
2 walk-away risks, 4 serious faults, 2 minor faults documented for this generation, weighted by severity and repair cost. Biggest factor: panoramic sunroof anti-trap / trim and water-ingress recall history. Score methodology.
The B8 Passat is the better global Passat: MQB chassis, strong space and efficient engines. The safe used buy is a 2019-2022 2.0 TDI with wet DSG and clean AdBlue/DPF data, or a petrol with smooth DQ200/DQ381 behaviour and no coolant loss. Avoid cars with unresolved sunroof/seat/ESP recalls, DSG judder, AdBlue countdown or water ingress.

Next checks
Before you contact the seller
Check the car's history first. Then bring the right tools if it still looks worth viewing.
Primary next step
Check history, title, and recall status
The faults above matter more if the car also has accident history, finance flags, missing service records, or open safety recalls.

Engines and trims
Which Volkswagen Passat should you buy?
On most used cars, the engine and trim choice changes the risk more than the mileage does. Narrow this down before you start viewing cars.
1.4 TSI / 1.5 TSI EA211
2015-2022
GOOD LIGHT-USE BUY
Efficient petrols; DQ200 DSG and 1.5 TSI drivability checks are key.
2.0 TSI
2015-2022 by market
FAST BUT RARER
Stronger and thirstier; inspect EA888 cooling and DSG service.
1.6/2.0 TDI EA288
2015-2022
BEST MOTORWAY BUY
Great if used hot and serviced; poor urban buy due to DPF/SCR costs.
Passat GTE PHEV
2015-2022
BUY ONLY WITH CHARGE TEST
Useful PHEV but battery, charger and DSG hybrid hardware need proof.
