Known problems
- Worth watching usually from 37,000 mi (60,000 km)
DPF clogging and oil dilution
Symptoms: frequent regenerations, limp mode from a blocked diesel particulate filter, and a rising, diesel-smelling oil level on cars used mostly for short trips
What to do: Give the car regular longer drives so the DPF can regenerate fully, use the correct low-ash diesel oil, and watch the oil level — if it climbs, change it, as fuel-diluted oil loses lubrication. Don't ignore DPF or limp-mode warnings.
- Worth watching usually from 50,000 mi (80,000 km)
EGR and intake carbon fouling
Symptoms: reduced performance and rough running as the EGR valve and intake manifold silt up with soot over time
What to do: Have the EGR valve and intake cleaned when performance drops (typically every 50,000-80,000 km), and use quality fuel to slow the buildup.
- Worth watching usually from 62,000 mi (100,000 km)
Diesel injector wear and cracked injector bores (4N15)
Symptoms: rough running, misfire, jerking or power loss above idle, and blow-by/seal leaks around the injectors; the cylinder head has thin injector walls that can crack if injectors seize and are forced out
What to do: Use clean, quality diesel and service the fuel filter on time; have injectors removed and refitted only by someone who torques them correctly and frees seized ones carefully, to avoid cracking the head. Investigate any misfire or power loss early.
- Good to know
Minor electronics niggles
Symptoms: occasional infotainment or electrical quirks; the ladder-frame chassis and mechanicals are otherwise durable
What to do: Keep software updated and address individual electrical faults as they appear; these are usability-level rather than a structural concern.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | diesel wise at ~10,000 km with correct low-ash oil; halve for dusty, short-trip or heavy-tow use — short trips promote DPF-related oil dilution |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Fuel filter (diesel) important | every 12,000 mi (20,000 km) | diesel — replace on schedule to protect the injection system |
| Air filter | every 19,000 mi (30,000 km) | sooner in dusty or off-road conditions |
| Automatic transmission fluid (Aisin 8-speed) important | every 56,000 mi (90,000 km) | service earlier for heavy towing or severe use |
| Brake fluid important | every 24 months | — |
| Timing chain (no belt) | — | both the 4N15 diesel and 6B31 petrol are chain-driven — no scheduled belt, but keep oil fresh |
Manufacturer-declared fuel economy
No manufacturer-declared figures for this model are in the Knowledge Base yet. A figure without the cycle it was measured under is not comparable to anything, so we publish none rather than a number you cannot interpret.
