2014 SEAT MII 1.0L Petrol · ML14 HJJ

The 2014 SEAT Mii currently holds no valid MOT, having failed its most recent test on 18 March 2026 at 162,023 miles. The maintenance trend is clearly worsening. Two consecutive failures in early 2026 reveal unresolved mechanical and emissions faults that have persisted or escalated since the January 2026 test. The vehicle is not roadworthy in its present state and requires significant remedial work before it can legally return to the road. The mileage accumulation tells an unusual story. Between the January 2025 pass at 145,733 miles and the January 2026 failure at 162,010 miles, the car covered approximately 16,277 miles in twelve months, a sharp increase compared to the 17,351 miles accumulated across the entire preceding twelve-month period between January 2024 and January 2025. Yet the recorded mileage at the March 2026 failure stands at 162,023, meaning only 13 miles were covered in over two months. This suggests the vehicle may have been taken off the road or used very little after the March failure, potentially leaving it stationary with unresolved faults. The high annual mileage overall points to sustained use, which typically accelerates wear on consumables and drivetrain components. The two most recent failures raise serious mechanical concerns that go beyond routine wear. A fractured or broken nearside front coil spring is a critical structural fault affecting suspension geometry and ride safety. This was present at the March 2026 test and demands immediate replacement. Both front brake discs were flagged as worn, pitted, or scored, and both front service brakes were recorded as fluctuating, indicating uneven braking force that points to worn pads, distorted discs, or caliper issues. The offside rear service brake was excessively binding in March, a condition that generates excessive heat, accelerates pad wear, and risks fuel economy loss or brake seizure. These braking faults across multiple axles suggest the entire system needs thorough inspection and likely overhaul. Beyond the suspension and braking defects, the recurring exhaust emissions failures are notable. Both the January and March 2026 tests recorded carbon monoxide exceeding manufacturer limits, with the January test also flagging hydrocarbon and lambda failures. This pattern points to a deteriorating catalytic converter, oxygen sensor fault, or engine management issue that has not been addressed across two consecutive tests. A prospective buyer should have a full emissions diagnostic carried out and budget for exhaust or engine management repairs. The repeated headlamp aim faults and minor oil leak noted in January 2026 further indicate a vehicle where basic upkeep has been neglected. Any in-person inspection should prioritise a thorough check of the front suspension assembly, all four brake calipers and discs, the exhaust system from manifold to catalyst, and a live emissions test under load.
