The Peugeot CFB (1KR) was used exclusively in the Peugeot 108 (B9) platform with transverse mounting. This engine is a licensed version of the Suzuki 1KR-FE, manufactured under agreement for the PSA-Toyota-Suzuki collaboration on the A-segment platform. No major hardware revisions affected core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
The CFB (1KR)'s primary reliability risk is ignition coil pack failure, with elevated incidence in vehicles subjected to frequent short trips and hot climates. Peugeot internal reports noted a cluster of misfire complaints requiring coil replacement before 80,000 km, while UK DVSA data indicates no major systemic failures beyond this. Adherence to spark plug replacement intervals is critical to reduce coil stress.
Analysis derived from Peugeot technical bulletins (2012-2021) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CFB is generally very reliable for a city car engine. Its main weakness is the ignition coils, which can fail prematurely, especially with frequent short trips. With regular maintenance, including timely spark plug changes and using the correct oil, these engines can easily last beyond 150,000 km without major issues.
The most frequent issue is ignition coil pack failure, leading to misfires. Minor oil consumption can occur in high-mileage engines, and thermostat housing leaks are occasionally reported. These are well-documented, with coil pack replacements covered under Peugeot service bulletin 14BZ09D.
This engine was used exclusively in the Peugeot 108 (B9) from 2012 to 2021, badged as the 1.0 VTi 68. It is a licensed version of the Suzuki 1KR-FE engine, also found in the Toyota Aygo and Citroën C1 of the same generation.
Tuning potential is very limited due to its small displacement and naturally aspirated design. ECU remaps offer minimal gains. Significant power increases would require forced induction, which is not practical or cost-effective for this engine in its intended application.
Fuel economy is excellent for city driving. In a Peugeot 108, expect combined figures of around 4.5 L/100km (63 mpg UK). Real-world consumption typically ranges from 5.0-6.0 L/100km (47-56 mpg UK), making it one of the most economical petrol engines available.
No. The CFB (1KR) is a non-interference engine. If the timing chain were to fail, the pistons and valves would not collide, preventing catastrophic internal damage. However, a broken chain will still leave the vehicle stranded and require repair.
Peugeot mandates the use of oil meeting the PSA B71 2030 specification, typically a 5W-30 viscosity. This ensures proper lubrication, fuel economy, and emissions system compatibility. Using the correct oil is essential for long-term engine health.
