Volkswagen Tiguan II (AD1) (2016 – 2024)

Reliability score : 7.6/10

The second-generation Volkswagen Tiguan (code name AD1 for the short wheelbase, BW1 for the long-wheelbase Allspace) is based on the famous VAG group's modular MQB platform. A true global best-seller, it has established itself through its spaciousness, rigorous finish, and abundant technological offerings. Restyled in late 2020 (phase 2), it modernized its front end and updated its infotainment system (MIB3), while introducing 'Evo' diesel engines with double AdBlue injection (Twin Dosing) and a plug-in hybrid version. Diesel Focus: In Europe, the 2.0 TDI accounted for the vast majority of sales, particularly popular with high-mileage drivers and families for its generous torque and fuel efficiency on the highway. Although powerful, this EA288 (then EA288 evo) engine requires rigorous moni

✅ Strengths

Excellent spaciousness and modularity (sliding rear bench, 7-seater Allspace version)
Enjoyment and fuel efficiency of the 2.0 TDI on long journeys
Efficiency of the 4Motion all-wheel drive and DSG gearbox (on wet-clutch versions)
Build quality and sound insulation (especially in phase 2)
Towing capacity (up to 2.5 tons on 2.0 TDI 4Motion)

⚠️ Weaknesses

Disastrous reliability of the AdBlue system (pump/tank) on TDIs
Fragile DSG7 (DQ200 dry-clutch) gearbox on small front-wheel-drive petrol engines
Very firm damping with 19/20-inch wheels (R-Line trim)
Frequent electronic bugs on the MIB3 multimedia system (post-2020)
High maintenance cost within the Volkswagen network

🎯 Verdict

The Volkswagen Tiguan II is a remarkably well-rounded family SUV. In its 2.0 TDI 150 hp version, it offers the best power/consumption compromise for high-mileage drivers. However, buying a used diesel model requires extreme vigilance regarding the condition of the AdBlue system and water pump. Avoid diesel if you primarily drive in the city (guaranteed clogging). For mixed or urban use, the 1.5 TSI 150 hp is a much more sensible and generally more reliable choice, provided you avoid the DSG7 DQ200 gearbox if possible, or ensure it is in perfect condition. Opt for a post-2019 model with a clear service history.
