2016 Mercedes-Benz GLA 2.1L Diesel · BW16 KNP

The 2143cc diesel engine is designed for efficiency, typically offering good motorway fuel economy, though actual costs will depend on driving style. As a 2016 model, tax bands will vary based on the specific CO2 emissions, but diesel models of this era generally fall into moderate tax brackets.

Insurance groups for the GLA vary, but the 2.1L engine often sits in a mid-range group. Maintenance costs should be factored in for periodic items like brake discs, pads, and tyres, which have appeared as advisories in recent MOT history. Estimated annual running costs, including fuel, tax, insurance, and maintenance, sit around £1,400-£1,700.

Focus your inspection on the braking system and tyres, as these were the primary areas of concern in the 2025 and 2026 MOT records. Specifically, check the thickness of the front brake pads and the condition of the rear brake discs to see if the 2025 advisories were addressed.

Given the aggregate data for this model, which highlights suspension arms, coil springs, and drive shaft joints as common failure points, it is wise to inspect the underside of the vehicle. Look for any signs of play in the suspension or excessive noise when driving over bumps, as these are frequent issues across the wider GLA population.
