- Typically appears
- 50,000-80,000 miles
- What to inspect
- Perform a cold start with the bonnet open. Listen closely to the top of the plastic cam cover for a distinct, rhythmic metallic slapping or rattling noise during the first minute of idling.

Build my inspection planFrequently asked questions
Is the PureTech belt a real problem?
Yes. No belt evidence means budget the job or walk.
Which version sells fastest?
Diesel automatics with seven usable seats.
Any electrical annoyance?
Touchscreen resets, usually fixed with a software update.
What are the implications of stocking the 1.5 BlueHDi over the 1.2 PureTech?
The 1.5 BlueHDi offers superior fuel economy for buyers doing heavy motorway miles, making it attractive for large families. However, you must ensure the AdBlue system is fault-free and check if the engine has the upgraded 8mm camshaft chain to avoid catastrophic failure. Short-journey buyers should be steered towards petrols to prevent DPF blockages.
Can the middle row accommodate three child seats?
Yes, a major selling point of the 5008 is that the second row features three individual, equally sized seats, each equipped with its own ISOFIX mounting points. This makes it highly desirable for families with three young children, giving it a distinct forecourt advantage over rivals like the Skoda Kodiaq or Nissan X-Trail.
Which trim level offers the best balance of equipment and reliability for the forecourt?
Allure trim is generally the sweet spot for dealers. It includes essential family features like rear parking sensors, privacy glass, and safety packs without the overly complex electrical additions found on GT-Line or GT models, such as massaging seats or panoramic roofs, which can become costly warranty liabilities as the vehicle ages.
