Build my inspection planFrequently asked questions
Is the BlueHDi diesel worth stocking?
For motorway buyers, yes. For town cars the emissions hardware becomes a warranty risk.
What breaks most on the 3008?
Electronics, especially the central screen.
Does the PureTech belt apply to the 1.6?
No, the wet belt problem is specific to the 1.2 PureTech three-cylinder.
Are there any specific forecourt checks for the PHEV hybrid models?
Yes. Check the charging flap mechanism, as the locking pin often jams. Ensure the Type 2 cable is present in the boot. On a test drive, force the car into electric mode to confirm the high-voltage battery holds charge and the transition to the petrol engine is seamless without drivetrain shudders.
How can I verify if the 1.2 PureTech has the updated timing belt?
You cannot definitively tell just by looking through the oil filler cap, though a smooth-backed belt indicates an older design, while a textured backing suggests the updated part. Always check the service history for a documented replacement invoice, as Peugeot revised the interval down to six years or 60,000 miles.
Why does the manual gearbox feel notchy going into second gear?
The six-speed manual transmission is naturally quite long-throw and can feel slightly resistant when cold. However, excessive crunching or refusal to engage second gear points to worn synchromesh rings. If the clutch pedal bite point is exceptionally high, budget for a replacement clutch and dual-mass flywheel, which exacerbates the notchiness.
