2.2L Diesel - 60kW (108 CDI)
Diesel
Turn the steering wheel from lock to lock while idling. Listen for groans or whines, as the power steering pumps on these W638 models can show their age through increased noise.
Gently accelerate in second and third gear. Notice if the engine surges or hesitates, as the Mass Air Flow (MAF) sensor is a common point of contention that can impact fuel efficiency.
Check this by idling for 5 minutes after a test drive. Look underneath the vehicle for any signs of fluid leaks, specifically checking around the gearbox casing, as seals can harden over time.
While stationary, shift through all gears including reverse. Feel for any excessive 'clunking' or hesitation, as the manual gear linkage bushes can wear, making gear changes feel less precise than they were when new.
Usually marks the time to inspect the condition of the turbocharger hoses for small cracks or fatigue.
A common point where the glow plugs may eventually require a bit of attention to ensure reliable winter starts.
Consider having a specialist inspect the suspension bushings and ball joints, as these contribute significantly to the van's handling and ride comfort.
Keep a close eye on your engine oil levels; the 2.2L diesel engine appreciates fresh oil and a high-quality filter every 10,000km.
Ensure the cooling system is kept fresh with the correct coolant type, as this is vital for the longevity of the alloy cylinder head.
Regularly clean the drain holes located beneath the windscreen scuttle panel to prevent water ingress into the cabin ventilation system.
Check the condition of the serpentine belt and tensioner; replacing these early can prevent a breakdown on the open road.
Inspect the tyres for uneven wear patterns, which can be an early indicator that a wheel alignment is due.
Estimated repair costs if issues arise
If the van feels like it has a bit of vibration at idle or the clutch pedal feel changes, it is common to consider planning for a clutch overhaul. This involves replacing the friction plate, pressure plate, and the dual-mass flywheel to ensure smooth power delivery.
Over many years of service, the intake hoses can develop small splits. Budgeting for these ensures your engine maintains its factory-intended torque and efficiency. It is a straightforward job for a local diesel specialist.
Depending on the roads the van has traveled, you might eventually need to budget for new shocks and suspension bushes. Doing this as a set can make a significant difference to the comfort of your ride.
