Audi Q3 F3 (2018–2025) (2018 – 2025)
Reliability score : 8.2/10
The second-generation Audi Q3 (Type F3) is based on Volkswagen Group's modular MQB A2 platform. Longer, wider, and significantly more spacious than its predecessor (8U), it corrects the main flaw of the first generation: the lack of space inside and in the trunk. Positioned as a premium compact SUV, it makes a major technological leap with the standard integration of the Virtual Cockpit and a tactile MMI interface. Although market trends are shifting towards hybridization and gasoline, diesel engines (TDI) remain a pillar of the range for high-mileage drivers. Equipped with the 2.0 TDI (EA288 Evo) block, the Q3 F3 offers excellent fuel efficiency on the highway, although these engines are penalized in strictly urban use by the complexity of their emission control systems (DPF, SCR/AdBlue).
✅ Strengths
- Significantly increased interior space compared to the previous generation (sliding rear bench standard).
- Remarkable fuel efficiency of 2.0 TDI engines on long journeys (often under 6 L/100 km).
- Careful sound insulation (wind and road noise well filtered).
- Technological ergonomics (very readable Virtual Cockpit, physical climate controls retained).
- Safe road handling and suspension comfort (especially with adaptive damping).
⚠️ Weaknesses
- Capricious and costly AdBlue emission control system for TDIs out of warranty.
- Hard plastics on door panels and lower center console (unworthy of the badge).
- Sluggishness and bugs in the MMI infotainment system on 2018-2020 models.
- High weight that penalizes the dynamism and fuel consumption of gasoline versions.
- Used car prices and cost of options (even on the second-hand market).
🎯 Verdict
The Audi Q3 (F3) is a mature, comfortable, and appealing compact SUV. Regarding diesel engines (35 and 40 TDI), the verdict is clear: these are excellent choices for high-mileage drivers covering more than 20,000 km per year, mainly on highways. Under these conditions, the 2.0 TDI proves to be indestructible and extremely frugal. However, if your use is mainly urban or suburban, avoid diesel. Failures related to clogging (DPF, EGR) and especially AdBlue system malfunctions (crystallization) will turn the experience into a financial nightmare. For mixed use, the 35 TFSI (1.5 gasoline) is the most rational and reliable choice in the range.
