The first-generation Peugeot 208 (codename A9) marked a major break for the lion brand. Replacing the 207, it introduced the famous 'i-Cockpit' (small steering wheel, raised instrument cluster, central touchscreen) and benefited from a drastic weight reduction (up to -110 kg compared to the 207), greatly improving agility and fuel consumption. Restyled in 2015 (new 3D lights, wider grille, multimedia update), it was a huge commercial success. However, its reliability record is heavily marred by major design flaws in its petrol engines (Prince and PureTech families) and its diesel emissions control systems (BlueHDi).
The Peugeot 208 I is an excellent car on paper, ruined by disastrous engineering choices for its engines. If you are looking for a petrol model, caution is advised: avoid 1.2 PureTech engines whose belt has not been recently changed and whose maintenance history is not clear. The older 1.4/1.6 VTi and THP also require great vigilance (chain). Paradoxically, the safest purchases for this generation are the diesels from before 2015 (1.4 HDi and 1.6 e-HDi). If you opt for a BlueHDi, make sure the AdBlue tank has already been replaced with the new reference.
