2015 Mercedes-Benz GLA 2.1L Diesel · BT65 DZF

The 2015 Mercedes-Benz GLA presents a stable and improving maintenance trend, culminating in a clean pass on 2 February 2026 at 89,075 miles with zero defects recorded. That clean sheet followed a failed test on the same day, where the tester flagged a malfunctioning tyre pressure monitoring system, excessive play in the offside front wheel bearing, worn rear brake pads below 1.5 mm, and an insecure rear exhaust heat shield. The fact that all four items were rectified before the pass test suggests the previous owner addressed the failures promptly rather than deferring them. The 2025 test tells a similar story: a fail on 5 February for an inoperative engine MIL, followed by a clean pass the next day at 79,810 miles. This pattern of failing and passing within 24 hours across two consecutive years indicates a reactive but responsible approach to compliance rather than chronic neglect. The mileage progression is consistent and unremarkable for an eleven-year-old vehicle. The car covered roughly 9,991 miles between the February 2025 pass at 79,810 miles and the February 2026 pass at 89,075 miles, which aligns with the annualised average of approximately 8,098 miles per year. There are no suspicious gaps or sudden spikes in accumulation that would suggest long periods of standing or odometer anomalies. The record is sparse, with only three test events across three years, but each one shows a clean pass outcome, which is a positive indicator of baseline roadworthiness. A buyer should still inspect the front suspension and wheel bearings in person, given the offside front wheel bearing failure flagged in February 2026. Excessive play in a wheel bearing can indicate underlying stress from road conditions or poor alignment, and a physical check for roughness or noise during rotation is advisable. The rear braking system also warrants attention. The rear pads were worn below the 1.5 mm minimum at the 2026 fail, and while they were clearly replaced before the pass, the condition of the rear brake discs should be examined for scoring or lipping, as pads worn that thin often operate on compromised disc surfaces. The insecure rear exhaust heat shield noted in the 2026 fail is a relatively minor item but one that can deteriorate further if left unattended. A buyer should verify the shield is firmly mounted and not rattling beneath the vehicle. The 2025 engine MIL fault, though resolved, suggests the car may have had an intermittent emissions-related fault code at some point. A diagnostic scan for stored or pending fault codes would provide reassurance that no underlying engine management issues persist. Overall, the MOT record paints a picture of a vehicle that is mechanically sound and well-maintained, with no recurring structural or systemic defects.
