2.0L (M 270) - CLA 220 / CLA 250
Petrol
Check the transmission during cold start and low-speed crawling. | Advice: In the C117, the 7G-DCT transmission can sometimes feel a bit hesitant. It is worth observing if there is any shuddering in lower gears, as this may indicate the dual-clutch system would benefit from a software update or a fluid service.
Inspect the dashboard and door card trim while stationary. | Advice: Commonly, these models can develop interior rattles or creaks as they age. It is helpful to test the fit and finish on uneven surfaces to ensure the cabin integrity is consistent with your expectations.
Observe the cooling system temperature gauge closely. | Advice: The M270 engine relies on efficient cooling. Ensure the temperature remains stable during your drive; monitoring this helps provide peace of mind that the thermostat and water pump are operating as intended.
Test the frameless windows operation at motorway speeds. | Advice: Since the CLA features frameless windows, it is sensible to verify that the seals effectively block wind noise and moisture, as rubber seals can naturally wear over time.
Consider a transmission fluid flush to maintain crisp gear shifts.
Time to inspect suspension components such as bushings and control arms.
Recommended interval to check the serpentine belt and tensioner assembly.
Ensure the logbook shows regular engine oil changes using high-quality synthetic lubricants.
Verify that the panoramic sunroof drainage channels have been cleared to prevent interior dampness.
Check that the electronic parking brake engages and releases smoothly without resistance.
Confirm the brake fluid has been flushed at the recommended two-year intervals.
Review the history for any previous coolant system maintenance to ensure the engine remains optimally cooled.
Estimated repair costs if issues arise
In cars of this age, it is common to consider that these cooling components may reach the end of their service life. If this component needs attention in the future, it is a sensible preventative measure to replace them together.
To keep your CLA shifting smoothly, you might eventually need to budget for a professional transmission fluid and filter service, which helps protect the internal clutch packs.
Depending on the road conditions the vehicle has faced, you may find that the control arm bushings require renewal to restore the factory-feel handling.
