2.0L M133 DE20 AL (280kW) - 4MATIC
Petrol
Listen for gearbox hesitation during low-speed maneuvers | Description: The AMG Speedshift DCT 7-speed transmission can be a bit jittery in stop-start traffic; ensure the shifts feel deliberate rather than slipping or shuddering.
Check the braking performance for pedal feel and vibration | Description: The GLA45 uses high-performance rotors and pads which can wear quickly if driven spiritedly; ensure there is no pulsing through the pedal under moderate braking.
Monitor the coolant temperature gauge during your drive | Description: These M133 engines run quite hot to achieve their power output; ensure the temperature remains stable and verify the cooling fans engage correctly once the engine is warm.
Inspect the front tires for uneven wear patterns | Description: Due to the aggressive factory alignment settings, check for 'feathering' on the inner edges of the tires, which might indicate suspension component wear or alignment needs.
Usually marks the interval for transmission fluid and filter service.
Often the window where spark plugs and potentially ignition coils may require attention to maintain peak performance.
A common point to review the status of the water pump and auxiliary drive belt tensioners.
Verify the service history confirms the use of Mercedes-approved high-performance synthetic oil.
Check that the panoramic sunroof seals are clean and the mechanism moves without straining.
Confirm that the 4MATIC all-wheel-drive system has had its differential fluid serviced as per the manufacturer's schedule.
Examine the interior trim and buttons, as soft-touch coatings can occasionally wear with high usage.
Ensure all digital driver assist features and infotainment connectivity are responsive and up-to-date.
Estimated repair costs if issues arise
These components are engineered for track-level performance. Depending on the car's driving history, you might eventually need to budget for a complete set replacement when the friction material reaches its limit.
Regular fluid and filter changes are vital for longevity. If this component needs attention in the future, it is best to use a specialist familiar with the AMG DCT system.
The M133 engine pushes significant boost pressure. It is common to consider setting aside a small fund for incidental cooling system hoses or sensors that may become brittle due to high heat cycles over time.
