DPF, EGR and AdBlue problems can catch out Navara buyers who don't ask how the truck has actually been used.
- Fuel Type
- Diesel
DPF Issues
The diesel particulate filter can become restricted, particularly when the vehicle is regularly used for short journeys and cannot complete a regeneration.
EGR Issues
Carbon can build up within the exhaust gas recirculation system, potentially causing warning lights, poor performance or uneven running.
AdBlue System Faults
AdBlue system problems can generate dashboard warnings and may eventually prevent the vehicle from restarting if they are not repaired.
What to Check Before Buying
- Check for engine-management, DPF and AdBlue warnings.
- Ask how the vehicle has previously been used.
- Check whether it regularly completed longer journeys.
- Look for invoices relating to the DPF, EGR or AdBlue system.
- Make sure there is no reduced performance or limp mode.
- Arrange a diagnostic scan before buying.
- Check that any stored or recently cleared fault codes are investigated.
Technician's Inside Tip
Do not assume every Navara has lived an easy life. Its previous usage is important, particularly if it has spent years towing, carrying heavy loads or making short journeys.
Final Verdict
The 2.3 diesel Navara needs careful inspection of its emissions equipment. A properly maintained example may still be worth considering, but unresolved DPF, EGR or AdBlue problems can become costly.
