Diesel
Check this by listening closely during a cold start. | Description: It is worth keeping an ear out for any rattling noises from the back of the engine bay, as the N47 engine's timing chain assembly can occasionally require inspection in high-mileage examples.
While driving at low speeds, observe the gear shifts. | Description: If you are looking at an automatic, pay attention to the smoothness of the shifts; occasionally, the transmission fluid may benefit from a flush to ensure continued longevity.
Check this by inspecting the exhaust smoke while accelerating. | Description: Keep an eye on the exhaust; excessive smoke may suggest that the DPF (Diesel Particulate Filter) has been worked hard, which is common if the car has mostly been used for short city trips rather than long highway runs.
While parked, check the undercarriage for dampness. | Description: It is wise to look for any signs of oil seepage around the engine block, as gaskets can begin to perish due to age and heat cycles in cars of this vintage.
Usually the point for checking suspension bushings and verifying the condition of the turbocharger.
A sensible time to inspect ancillary belts and the water pump assembly for peace of mind.
Consider a full cooling system refresh and a deep diagnostic check of all electronic modules.
Ensure the oil has been changed strictly every 10,000 to 12,000km, rather than relying solely on the long-life computer indicator.
Verify that the brake fluid has been flushed at least every two years to protect the ABS pump.
Keep the engine air filter clean to assist with fuel efficiency and DPF health.
Regularly use a high-quality diesel fuel additive to help keep the fuel injectors clean.
Check the cabin air filter regularly to ensure your heating and cooling system operates efficiently.
Estimated repair costs if issues arise
While not guaranteed to fail, some owners choose to proactively replace these as a preventative measure to ensure complete peace of mind. This is a significant labor-intensive job as it sits at the rear of the N47 engine.
If the car has lived primarily in urban traffic, the DPF might eventually become clogged. A professional clean or an on-car forced regeneration can often resolve this before a total replacement is required.
As these cars age, the original suspension components may lose their composure. Budgeting for a freshen-up of the front struts and rear shock mounts can significantly restore the 'BMW driving feel'.
