Land Rover Discovery Sport MOT Failures
An analysis of 1,488,326 real DVSA MOT tests on the Land Rover Discovery Sport — what fails, how often, and how that compares to every other car on UK roads. Generations covered: L550 (2014–2024).
Where the Land Rover Discovery Sport fails its MOT
The single biggest MOT failure point on the Land Rover Discovery Sport is front or rear fog lamp with a multiple light so... — this model is 83 times more likely to fail on this item than the average car on UK roads. That makes it a major concern for anyone buying or owning this model. Across 1,488,326 MOT tests, 0.23% of all Land Rover Discovery Sport tests recorded this as a failure.
Lighting faults are usually straightforward to fix (bulbs, connectors, earth points) but can indicate deeper wiring issues on older cars. Check all lights including fog lamps, number plate lights, and dashboard warning lights.
Other notable weak points include emissions failure (9.1x the fleet average), obligatory rear fog lamp missing, or a front or... (59x the fleet average), service brake efficiency below minimum requirement (14x the fleet average), and headlight fault (18x the fleet average). These ratios compare the Land Rover Discovery Sport's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 4 categories: Lights & Electrics, Exhaust & Emissions, Brakes, Bodywork. If you're inspecting a Land Rover Discovery Sport before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Land Rover Discovery Sport's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Land Rover Discovery Sport specifically, the DVSA data shows the most common failures at this mileage are front or rear fog lamp with a multiple light so... (83x the average) and obligatory rear fog lamp missing, or a front or... (59x). service brake efficiency below minimum requirement (14x) and lens defective which has no effect on emitted l... (14x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Land Rover Discovery Sport specifically, the DVSA data shows the most common failures at this mileage are obligatory rear fog lamp missing, or a front or... (34x the average) and front or rear fog lamp with a multiple light so... (33x). front or rear fog lamp emitted colour, position... (14x) and service brake efficiency below minimum requirement (8.0x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Land Rover Discovery Sport specifically, the DVSA data shows the most common failures at this mileage are front or rear fog lamp with a multiple light so... (57x the average) and headlight fault (18x). emissions failure (8.2x) and brake lining or pad worn down to wear indicator (6.0x) also appear frequently.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Land Rover Discovery Sport specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
DPF blockage and excessive smoke opacity (L550) Major
The diesel particulate filter (DPF) blocks with soot on Discovery Sport diesel engines, particularly on vehicles used for short urban journeys that do not reach full operating temperature regularly. Affects L550; typical independent garage repair cost is £300–£600.
Premature suspension component wear (L550) Major
Discovery Sport models experience premature wear of suspension bushes, ball joints, and control arm components. Affects L550; typical independent garage repair cost is £300–£800.
9-speed automatic transmission malfunction (L550) Major
The 9-speed automatic transmission fitted to Discovery Sport models can suffer from internal component failures leading to complete loss of drive or transmission entering failsafe mode. Affects L550; typical independent garage repair cost is £2,500–£4,000.
Exhaust system corrosion and leaks (L550)
Discovery Sport models suffer from premature exhaust system corrosion and component failure. Affects L550; typical independent garage repair cost is £200–£600.

What to check before buying a Land Rover Discovery Sport
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Land Rover Discovery Sport:
Lights & Electrics — check for front or rear fog lamp with a multiple light so..., obligatory rear fog lamp missing, or a front or..., headlight fault, lens defective which has no effect on emitted l..., front or rear fog lamp emitted colour, position.... Exhaust & Emissions — check for emissions failure. Brakes — check for service brake efficiency below minimum requirement.
Beyond the MOT items, ask specifically about dpf blockage and excessive smoke opacity and premature suspension component wear. These won't show up on a standard MOT but can be expensive to fix — repairs start from £300. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
