About the 2019 MERCEDES UNCLASSIFIED

The 2019 MERCEDES UNCLASSIFIED is a family car with a 2143cc diesel engine. 176 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 16% of all 2019 cars for reliability.

With an average of 25,080 miles at 7 years old, MERCEDES UNCLASSIFIED owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

2019 MERCEDES UNCLASSIFIED Fuel Costs

The 2143cc diesel engine offers a reasonable balance between performance and economy. Expect around 40 mpg in mixed driving, which works out to roughly £1,245 per year at current diesel prices of 148p per litre (based on 7,400 miles per year). Diesel cars of this age should have their DPF (diesel particulate filter) checked, as replacements can be costly.

What does it cost to own a 2019 MERCEDES UNCLASSIFIED?

Total estimated annual running cost is £1,695 141/month), broken down as £1245 fuel, £195 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 95% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

MERCEDES UNCLASSIFIED Reliability Trend

Newer MERCEDES UNCLASSIFIEDs show better MOT pass rates than older ones, with an average improvement of 13 percentage points.

Buying a Used 2019 MERCEDES UNCLASSIFIED

At 7 years old, this is a solid used buy if you find one with good service history. Depreciation has levelled off, so you won't lose much more value. Focus on condition over mileage. If you're flexible on year, the 2021 model has the highest pass rate at 96%.

Common Issues to Watch For

Based on the 2019 MERCEDES UNCLASSIFIED's fuel type, age, and engine size, these are the most likely problem areas to check.

DPF (Diesel Particulate Filter)

Watch out

Short journeys clog the DPF. Replacement costs £1,000-£2,500. Check the DPF warning light and ask about driving patterns.

Turbo Wear

Medium risk

Diesel turbos work harder and wear faster. Listen for whining noises and check for oil leaks around the turbo housing.

AdBlue System

Medium risk

Post-2015 diesels use AdBlue for emissions. Sensor failures and tank heater issues are common. Budget £200-£500 for repairs.

EGR Valve

Watch out

Exhaust Gas Recirculation valves clog with carbon deposits, causing rough running and poor economy. Cleaning costs £150-£300, replacement £300-£600.

Dual Mass Flywheel

Watch out

Larger diesel engines put extra strain on the dual mass flywheel. Listen for rattling at idle. Replacement with clutch is £800-£1,500.

Suspension Wear

Medium risk

Shock absorbers, springs, and anti-roll bar links typically need attention around this age. Listen for clunks over bumps and check for uneven tyre wear.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
