MAN Tge 3.140 MOT Failures
An analysis of 13,035 real DVSA MOT tests on the MAN Tge 3.140 — what fails, how often, and how that compares to every other car on UK roads. Generations covered: Gen1 (2017–2024).
Where the MAN Tge 3.140 fails its MOT
The single biggest MOT failure point on the MAN Tge 3.140 is emissions failure — this model is 9.4 times more likely to fail on this item than the average car on UK roads. That makes it worth watching for anyone buying or owning this model. Across 13,035 MOT tests, 1.7% of all MAN Tge 3.140 tests recorded this as a failure.
Exhaust and emissions failures often point to catalytic converter degradation, lambda sensor faults, or — in diesel models — DPF problems. These can be expensive to fix and will cause an immediate MOT failure.
Other notable weak points include reflector defective or damaged by up to 50% of ... (13x the fleet average) and transmission shaft constant velocity joint boot... (8.1x the fleet average). These ratios compare the MAN Tge 3.140'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 3 categories: Exhaust & Emissions, Lights & Electrics, Bodywork. If you're inspecting a MAN Tge 3.140 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 MAN Tge 3.140'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 MAN Tge 3.140 specifically, the DVSA data shows the most common failures at this mileage are reflector defective or damaged by up to 50% of ... (13x the average) and emissions failure (9.4x). transmission shaft constant velocity joint boot... (8.1x) and transmission shaft constant velocity joint boot... 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 MAN Tge 3.140 specifically, the DVSA data shows the most common failures at this mileage are reflector defective or damaged by up to 50% of ... (7.4x the average) and emissions failure (7.1x).
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 MAN Tge 3.140 specifically, the DVSA data shows the most common failures at this mileage are reflector defective or damaged by up to 50% of ... (8.2x the average) and emissions failure (7.0x).

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 MAN Tge 3.140 specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Engine management light - emissions system fault (Gen1) Major
The 2.0 TDI engine shows a statistically elevated rate of engine management light illumination, particularly from 60,000-80,000 miles where it fails MOT at This typically indicates DPF (diesel particulate filter) blockage, EGR valve carbon buildup, or emission sensor failures. Affects Gen1; typical independent garage repair cost is £300–£800.
DPF blockage and regeneration issues (Gen1) Major
Commercial vehicles used for short journeys or urban delivery work frequently experience DPF blockages because the exhaust system does not reach the temperature required for automatic regeneration. Affects Gen1; typical independent garage repair cost is £400–£800.
CV joint boot failure (Gen1)
The TGE shows elevated CV joint boot failure rates, peaking at 5.5 times the fleet average between 40,000-60,000 miles. Affects Gen1; typical independent garage repair cost is £80–£150.
Excessive fluid leakage (Gen1)
This indicates significant oil, coolant, or hydraulic fluid leaks developing relatively early in the vehicle's life. Affects Gen1; typical independent garage repair cost is £150–£600.

What to check before buying a MAN Tge 3.140
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a MAN Tge 3.140:
Exhaust & Emissions — check for emissions failure. Lights & Electrics — check for reflector defective or damaged by up to 50% of .... Bodywork — check for transmission shaft constant velocity joint boot....
Beyond the MOT items, ask specifically about engine management light - emissions system fault and dpf blockage and regeneration issues. 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.
