Expert verdict
Steering accounts for 13.2% of everything recorded on the 2014 Mercedes-Benz Motorhome, against 2.6% nationally — 10.6 points above. Brakes are still the single largest share at 27.6%, but at 20.9% nationally that one is ordinary. Ask for the steering to be checked for play with the wheels on the ground, not on a jack.
Written from this page's own figures: fault shares against the national composition, the like-for-like pass rate, and the priced repair list. How these are worked out
Watching a Mercedes-Benz Motorhome? Get an email when these numbers change .
Every Mercedes-Benz motorhome first registered in 2014 is combined here — 6 trim and body variants in total — so the sample is as large as the DVSA data allows.
Cars of this age and mileage average 80.2%, so this figure is 2.6 points ahead of what its age and mileage predict. On a first attempt, before any retests, the figure drops to 79.6%. The median 2014 Mercedes-Benz motorhome in this dataset had covered 37,342 mi.
The single most recorded failure item is "Windscreen damaged but not adversely affecting driver's view", noted on 7.81% of tests.
Figures count every completed test on this vehicle-year in the dataset, including retests. See methodology for the exact definition.

Windscreen
Typically a garage job — get quotes before committing.
Pass rate by odometer reading. Bar lengths start at 67% so small gaps stay visible.
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
Check the windscreen 7.8% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
Check the lights 6.3% of tests
“registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
Check the suspension joints 1.6% of tests
“ball joint excessively worn”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
Across the 10 items that are recorded most often on this model, the average repair comes to £27–£72 — and 59% of those repairs are parts that cost under £30.
Estimates from typical UK parts prices, weighted by how often each item appears in 64 MOT tests on this vehicle. They exclude diagnostics, retest fees and garage labour where the part is a DIY fit, and they are not figures from the DVSA dataset. Older and higher-mileage examples cost more than the average.

21 model years on record, from 2000 to 2022. Across them the pass rate runs from 75.4% to 95.0% — a spread of 19.6 points. The bar under each year is the item that failed it most often.
Colour is the pass rate on a fixed scale, so a block means the same thing on any model. Each year links to its own page with the full fault breakdown.
The raw pass rate mostly measures age. The year comparison adds the like-for-like figure, the mileage bands and the repair bill.
Closest pass rates among 2014 motorhomes with at least 150 tests, so a small sample cannot flatter itself into the list. Full rankings: best motorhomes and worst motorhomes for MOT pass rates.
Shares of the 76 individual items recorded on this vehicle, and the same share across all cars nationally. A single test can record several items, so a row is not a percentage of tests.

Severity is as recorded: Major and Dangerous fail the test outright; Minor and Advisory do not. Costs are estimates from typical UK parts prices — see how they are built.
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.
