Mercedes Benz Viano (2012)
2012 Mercedes Benz Viano
CarHunch analysed 763 real MOT records for the 2012 Mercedes Benz Viano. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2012 Mercedes-Benz Viano passes its MOT at 81.4%, marginally above the UK average of 80%, but a serious concern emerges in the safety data: 38.5% of these vans have recorded dangerous defects at some point, well above the threshold that should worry a potential buyer. This high rate of critical issues makes thorough pre-purchase inspection non-negotiable.
At nearly 102,000 miles on average, these vans have covered typical mileage for their age, yet they're racking up an average of 2.91 failures and 15.3 advisories per test—suggesting wear and maintenance demands accumulate steadily. Before committing to one, have a Mercedes specialist conduct a full diagnostic focusing on brake systems and suspension components, where dangerous defects are most commonly recorded on this model.
What to check before buying a 2012 Mercedes Benz Viano
