About the 2016 DETHLEFFS UNCLASSIFIED
The 2016 DETHLEFFS UNCLASSIFIED is a large car with a 2300cc diesel engine. 36 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 10% of all 2016 cars for reliability.
With an average of 23,817 miles at 10 years old, DETHLEFFS 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.
2016 DETHLEFFS UNCLASSIFIED Fuel Costs
The 2300cc 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 2016 DETHLEFFS UNCLASSIFIED?
Total estimated annual running cost is £1,895 (£158/month), broken down as £1245 fuel, £395 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 97% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.
Buying a Used 2016 DETHLEFFS UNCLASSIFIED
At 10 years old, the DETHLEFFS UNCLASSIFIED is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age. If you're flexible on year, the 2019 model has the highest pass rate at 99%. Note: with only 36 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 2016 DETHLEFFS UNCLASSIFIED's fuel type, age, and engine size, these are the most likely problem areas to check.
DPF (Diesel Particulate Filter)
Watch outShort journeys clog the DPF. Replacement costs £1,000-£2,500. Check the DPF warning light and ask about driving patterns.
Turbo Wear
Watch outDiesel turbos work harder and wear faster. Listen for whining noises and check for oil leaks around the turbo housing.
AdBlue System
Medium riskPost-2015 diesels use AdBlue for emissions. Sensor failures and tank heater issues are common. Budget £200-£500 for repairs.
EGR Valve
Watch outExhaust Gas Recirculation valves clog with carbon deposits, causing rough running and poor economy. Cleaning costs £150-£300, replacement £300-£600.
Dual Mass Flywheel
Watch outLarger diesel engines put extra strain on the dual mass flywheel. Listen for rattling at idle. Replacement with clutch is £800-£1,500.
Rust and Corrosion
Watch outAt 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.
Suspension Bushings
Watch outRubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.
Service History
Low riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
