Build my inspection planYes, it is practical and generally reliable, sharing proven mechanicals with the Berlingo.
AdBlue and DPF related warning lights, especially on urban-use examples.
Yes, worn rollers or tracks can cause sticking, so test both doors fully.
The 1.2 PureTech uses a wet timing belt that can degrade and block the oil pickup. Check the service history for strict adherence to oil change intervals using the correct specification oil. On the forecourt, remove the oil filler cap and shine a torch inside to check the belt's surface for swelling or fraying.
The eight-speed EAT8 gearbox is generally robust but can suffer from jerky downshifts or hesitation when pulling away. During a test drive, ensure transitions between gears are smooth, particularly from second to first when coming to a halt. Rough shifting often requires a software update or a fluid change to rectify.
Early 1.5 BlueHDi units used a 7mm internal camshaft chain that is prone to stretching and snapping, causing catastrophic engine failure. Peugeot later revised this to an 8mm chain. You should listen for top-end rattling on cold start and check if the cam cover has the updated prominent bulge indicating the 8mm chain housing.
