About the 2006 MERCEDES MOTORHOME
The 2006 MERCEDES MOTORHOME is a performance with a 4250cc diesel engine. 122 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 17% of all 2006 cars for reliability.
With an average of 64,969 miles at 20 years old, MERCEDES MOTORHOME 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.
2006 MERCEDES MOTORHOME Fuel Costs
The 4250cc 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 MOTORHOME?
Total estimated annual running cost is £2,385 (£199/month), broken down as £1245 fuel, £735 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 84% pass rate. Keeping on top of servicing will help avoid surprises.
MERCEDES MOTORHOME Reliability Trend
Newer MERCEDES MOTORHOMEs show better MOT pass rates than older ones, with an average improvement of 9 percentage points.
Buying a Used 2006 MERCEDES MOTORHOME
At 20 years old, the MERCEDES MOTORHOME 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 2007 model has the highest pass rate at 95%.
Common Issues to Watch For
Based on the 2006 MERCEDES MOTORHOME'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.
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.
