Peugeot 106 I (1A/C) (1991 – 1996)

Reliability score : 8.2/10

Launched in September 1991, the Peugeot 106 Phase 1 (codename 1A for the 3-door, 1C for the 5-door which appeared in 1992) had the heavy task of succeeding the 104 while supporting the legendary 205. A light, agile city car with excellent road handling typical of Peugeot, it left its mark on the 90s. Diesel Focus: The 106 had two diesel eras. The first (1992-1994) with the 1.4D (TUD3) aluminum block, known to be fragile. The second (1994-1996) with the 1.5D (TUD5) cast iron block, which became a true legend of automotive reliability, capable of exceeding 400,000 km with basic maintenance, while consuming less than 5L/100 km. Although passive safety is dated, it is an economical 'runabout' par excellence.

✅ Strengths

Exceptional reliability and longevity of the 1.5D (TUD5) engine
Extremely low fuel consumption (often under 5L/100km for diesel)
Lively, precise, and fun road handling
Negligible maintenance, insurance, and spare parts costs
Excellent mechanical accessibility (plenty of space under the hood)

⚠️ Weaknesses

Disastrous reliability of the first 1.4D (TUD3) diesel engine
Fragile trailing arm rear axle (a common PSA issue of the era)
Passive and active safety from another era (no ABS, no airbags, thin sheet metal)
Almost non-existent sound insulation, especially in diesel models
Very poor standard equipment on entry-level trims (XN, Kid)

🎯 Verdict

The Peugeot 106 Phase 1 is an endearing city car that embodies the transition between the 80s and 90s. If you are looking for a diesel, the choice is binary: avoid the 1.4D (TUD3) and go for the 1.5D (TUD5). The 1.5D is a true workhorse, capable of handling astronomical mileages for an unbeatable running cost. It's the perfect 'daily driver' for small budgets, provided you accept rustic comfort, poor sound insulation, and old-generation safety. Before purchase, inspection of the rear axle is absolutely mandatory, as its repair can cost more than the car's value.
