Is the Mercedes-Benz Citan reliable?

On MOT evidence the Mercedes-Benz Citan is well below average. It passes 65.2% of tests once age and mileage are accounted for, against a national average of 72.3%. That figure covers 74% of the national age and mileage range, which is enough to quote but not to rank. This measures how often the car meets the MOT standard, not how often it breaks down or what a repair costs.

What do testers most often warn about on a Mercedes-Benz Citan?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 32.8% of all Mercedes-Benz Citan tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Mercedes-Benz Citan usually have at its MOT?

The average odometer reading recorded at test is 105,208 miles. This is the mileage across all tested examples of every age, not an annual figure, so treat it as a description of the fleet rather than a target for one car.

Which Mercedes-Benz Citan years are the most reliable?

Going by MOT pass rate, Mercedes-Benz Citan cars first registered 2020–2022 do best at 70.3%, and those registered 2011–2013 do worst at 51.9%. But that ordering is mostly age, not build year: almost every model passes less often as it wears, so the newest cars top this list whatever they are. A specific year looking strong here means little on its own; the failure items above, and the individual car's own MOT history, tell you far more.

Does a Mercedes-Benz Citan get harder to pass as it ages?

Yes. At 3 to 5 years old, 70.3% of Mercedes-Benz Citan tests pass. By 12 to 14 years, that falls to 51.9%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most Mercedes-Benz Citan models petrol or diesel?

Of the Mercedes-Benz Citan cars tested, 98% are diesel, 2% are petrol. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

From 19,945 recorded MOT tests of the Mercedes-Benz Citan, published by DVSA.

Data updated 29 July 2026

Quick answer

The Mercedes-Benz Citan passes 65.2% of MOT tests once results are adjusted for the age and mileage of the cars tested, against a national average of 72.3%. That is well below average. Based on 19,945 tests. Its most commonly recorded failure is transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc, which appears in 25.0% of failed tests. Cars of this model average 105,208 miles on the odometer when tested.

Known faults

Mercedes-Benz Citan common problems, by part and by year

The same failure record read the way a buyer asks the question: which parts wear out on a Citan, when they start, and how each registration year compares — including the steps that mark a generation change.

How wear changes the picture

Citan pass rate by age and registration year

How often the Mercedes-Benz Citan passes at each age, with the years those cars were first registered. Tests are from 2025, so a car aged 3 to 5 was first used in 2020–2022.

3–5 yrsreg. 2020–202270%

6–8 yrsreg. 2017–201962%

9–11 yrsreg. 2014–201657%

12–14 yrsreg. 2011–201352%

Read this as an age curve rather than a verdict on particular model years. Nearly every car passes less often as it gets older, so a newer Citan outscoring an older one says more about wear than about how that year’s cars were built. Bands holding too few tests to be meaningful are omitted rather than shown as a rate.

How this was worked out

Method and limits

Figures come from the DVSA anonymised MOT testing dataset, published under the Open Government Licence. Only class 4 initial tests are counted: retests are excluded so a car appears once, and abandoned tests are excluded entirely. The adjusted rate is directly standardised across twenty-five age and mileage bands and reweighted onto the national distribution, so this model is compared against cars that have lived a similar life rather than against a younger or lighter-used fleet.

An MOT measures whether a car met a legal standard on the day. It is not a breakdown record, a service history or a running-cost estimate, and a pass rate is a property of a fleet rather than a prediction about one car.
