1.7L CRDi (High Power) - Elite/Premium trim
Diesel
Check the Dual Clutch Transmission (DCT) operation | Detail: While driving in stop-start traffic, pay close attention to the smoothness of gear changes. In cars of this age, it is common to consider that the clutch pack may show signs of wear, which can manifest as slight shuddering or hesitation at low speeds.
Inspect the Electronic Parking Brake (EPB) | Detail: Check this by engaging and disengaging the parking brake multiple times while stationary. It is worth noting that the electronic actuators can occasionally become sluggish over time, so ensure the system responds promptly without unusual grinding noises.
Verify the Panoramic Sunroof functionality | Detail: If the model is equipped with the sunroof, open and close it fully during your test drive. It is common for the runner tracks to accumulate debris or lose lubrication, which may lead to slower operation or jamming.
Examine the DPF (Diesel Particulate Filter) status | Detail: While driving on an open road, observe if there are any warning lights or loss of power. In high-mileage diesel engines of this type, it is common to consider that the DPF may reach its capacity if the car has mostly been used for short city trips.
Usually marks the point for a significant transmission fluid flush and check of the suspension bushings.
A common interval to check the integrity of the turbocharger and inspect the timing chain components for any signs of stretching or noise.
Consider a comprehensive cooling system health check and potential refurbishment of the alternator or starter motor.
Ensure the oil changes have been strictly adhered to every 10,000-15,000km, as these CRDi engines appreciate clean, high-quality synthetic oil.
Verify that the transmission fluid has been changed according to the schedule to maintain the longevity of the DCT.
Check that the air filter and fuel filter have been replaced regularly to keep the diesel injection system running optimally.
Keep an eye on the brake fluid levels and condition, as this is often overlooked but crucial for safety in heavier touring vehicles.
Monitor the condition of the drive belt and tensioner, especially if the vehicle has exceeded 120,000km.
Estimated repair costs if issues arise
If this component needs attention in the future, it is a significant job involving the replacement of the friction plates. Depending on the car's history, you might eventually need to budget for this if you notice persistent shuddering.
Should the DPF become blocked due to lack of highway driving, it may require a professional forced regeneration or a full replacement. It's a good idea to set aside funds for this if your commute is primarily short urban trips.
The i40 is a comfortable tourer, but the weight of the diesel engine can lead to wear on front suspension bushings over time. If you hear knocking over bumps, budgeting for a refresh of the control arm bushings is a wise future plan.
