2.1L Turbo Diesel (GLA 200 d) - FWD
Diesel
Listen carefully for any 'fluttering' or whining noises during acceleration, as the turbocharger seals on the OM651 engine can occasionally show signs of wear as they age.
Cycle through every gear in the 7G-DCT transmission while slowing down; ensure the downshifts feel smooth, as jerky behavior might suggest the mechatronics unit or fluid is due for attention.
Turn the steering wheel fully to both locks while stationary to listen for any clicking or grinding, which can indicate the CV joints or suspension bushings are nearing the end of their service life.
Spend a moment checking the panoramic sunroof (if fitted) operation; ensure it opens and closes without stuttering, as the tracks can collect dust and debris in our NZ climate.
Usually the time to inspect the auxiliary drive belt and tensioner to ensure no cracking is present.
A common point for DPF (Diesel Particulate Filter) health checks and potential intake manifold cleaning to maintain efficiency.
Often recommended for the transmission fluid and filter service to keep the dual-clutch system shifting like new.
Check the service history logbook for regular oil changes every 10,000 to 15,000km using the correct low-ash synthetic oil.
Inspect the tyre tread for uneven wear patterns, which can be an early indicator that the wheel alignment needs a quick refresh.
Confirm the air conditioning blows ice-cold, as these systems appreciate a regular gas check to prevent the compressor from overworking.
Verify the coolant reservoir level and check the colour of the fluid to ensure it has been kept fresh for optimal engine temperature regulation.
Examine the brake pads and rotors for any ridges, as these heavier diesel models can be a bit more demanding on their braking components.
Estimated repair costs if issues arise
While it doesn't need doing all the time, keeping this fluid fresh is key to longevity. If this component needs attention or a full service in the future, the estimated cost in NZ is usually higher than a manual gearbox service.
If you mostly do short city trips, the DPF might not get hot enough to clear itself. Depending on the car's history, you might eventually need to budget for a professional forced regeneration or a deep clean.
Our roads can be tough on suspension. If this component needs attention in the future as the car reaches higher mileage, it's worth having a technician check the bushings during your regular service.
