2011 MINI ONE 1.6L Petrol · NU61 YRL

The vehicle shows a history of recurring mechanical issues that suggest a reactive approach to maintenance. In the most recent test in April 2026 at 103,049 miles, the car failed initially due to high carbon monoxide and lambda readings, alongside an exhaust leak at the front downpipe flexi. While it passed shortly after, the tester noted corrosion on the rear sub-frame. This specific exhaust leak was also present during the March 2025 test at 100,989 miles, where the vehicle also failed on emissions, indicating a persistent fault in the exhaust system that was not immediately addressed. At 103,049 miles over 15 years, the car averages roughly 6,900 miles per year, which is consistent with typical usage. However, the data reveals a significant decline in upkeep following the clean February 2024 test at 100,524 miles. Within a single year, the vehicle suffered multiple failures involving electrical faults, including a supplementary restraint system (SRS) warning lamp, low headlamp aim, and low pressure across all four tyres. The repeated mention of low coolant levels across the three most recent tests suggests a persistent leak or cooling system inefficiency that the owner has overlooked. The structural integrity of the rear sub-frame requires close monitoring. Although the tester classified the corrosion as not seriously weakened in 2026, rust on these components in this era of MINI often progresses to structural failure if untreated. The binding offside rear service brake noted in 2025 is also a sign of a seized caliper or worn slider pins. A buyer should verify that the exhaust flexi has been replaced and that the SRS fault has been properly diagnosed, as these issues represent genuine safety and emissions concerns beyond simple consumable wear.
