2.1L Diesel - 70kW (109 CDI)
Diesel
Observe the gear shifts while driving through local streets. It is worth noting that if shifts feel harsh or hesitant, the transmission fluid may be due for a service, which is common for vans of this vintage.
Check the dashboard for warning lights after idling for a few minutes. Occasionally, the DPF (Diesel Particulate Filter) system can trigger a light if the van has been used predominantly for short, low-speed city trips.
Turn the steering lock-to-lock while stationary. In these W639 models, it is helpful to listen for any groaning sounds, as the power steering pumps can show signs of age with higher mileage.
Operate every electrical switch, specifically the sliding door mechanisms. It is a good practice to ensure they glide smoothly, as the rollers and latch mechanisms are frequent wear items that may need lubrication or adjustment.
Usually the time to inspect suspension bushes and ball joints for any play.
A common point to verify if the alternator and starter motor have had any previous maintenance.
A stage where proactive assessment of the turbocharger's boost pressure and hose integrity is often recommended.
Check the engine oil level and colour; regular, high-quality oil changes are the best way to look after that 2.1L turbo-diesel engine.
Inspect the tyres for uneven wear, which is often a polite hint that an alignment or suspension refresh might be in order.
Look underneath for any signs of surface rust, especially around the rear wheel arches and under-chassis rails, which is sensible for NZ coastal conditions.
Test the heating and cooling system thoroughly, as these vans have large cabins that rely on well-maintained fans and air conditioning condensers.
Ask to see the service history, particularly records of fuel filter changes, which are crucial for maintaining healthy fuel injectors.
Estimated repair costs if issues arise
If the van has spent much of its life doing stop-start city driving, the DPF might eventually need a professional deep clean or, in rarer cases, a replacement. Future Budget Planning suggests keeping an eye on your exhaust performance.
As these vehicles often carry heavy loads, the suspension components take on quite a bit of work. Depending on the car's history, you might eventually need to budget for new shocks or control arm bushes to maintain that comfortable ride quality.
The 2.1L engine is a workhorse, but the copper seals on the injectors can deteriorate over high mileage. If this needs attention in the future, it is best to address it early to keep the engine top-side clean and running efficiently.
