About the 2006 MERCEDES 280

The 2006 MERCEDES 280 is a large car with a 2746cc diesel engine. 39 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. Among all cars from 2006, the average MOT pass rate is 73%, and this model beats that benchmark.

With an average of 125,816 miles at 20 years old, MERCEDES 280 owners drive about as much as the UK average.

2006 MERCEDES 280 Fuel Costs

The 2746cc diesel engine is on the larger side, so fuel won't be this car's strong point. 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 2006 MERCEDES 280?

Total estimated annual running cost is £2,195 183/month), broken down as £1245 fuel, £395 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 79% pass rate. Keeping on top of servicing will help avoid surprises.

Buying a Used 2006 MERCEDES 280

At 20 years old, the MERCEDES 280 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. Note: with only 39 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

Based on the 2006 MERCEDES 280'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

Watch out

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

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.

Rust and Corrosion

Watch out

At 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 out

Rubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.

Clutch Wear

Watch out

With an average of 126k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.

Brake Discs and Pads

Medium risk

High-mileage cars often need brake disc replacement, not just pads. A full set of discs and pads costs £200-£500 per axle.

Engine Mounts

Medium risk

Worn engine mounts cause excessive vibration and movement. Replacement costs £150-£400 per mount. Check for vibration at idle with the bonnet open.

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.
