Volkswagen Passat Common Faults in the UK
B8, 2015–2023 — mid-size family saloon and estate. Updated 2026-05-04.
The B8 VW Passat (2015–2023) is mostly reliable but pre-2018 DSG DQ200 mechatronic failures around 120,000 km are well-documented, and EA288 diesels need EGR cooler recall verified. Post-2018 examples with DQ381 gearbox are far more durable. Best-buy: 2019–2021. Worst: 2015–2017 DSG.

Best and worst years to buy
Post-2018 cars use the wet-clutch DQ381 gearbox which is significantly more durable than the dry-clutch DQ200. EGR recall completed on most by 2019. AdBlue dosing more reliable.
DQ200 dry-clutch DSG failures around 120,000 km are common, with full mechatronic replacement at £1,500–£2,500. Many Irish dealers refuse pre-2018 DSG Passats in part-exchange.
