About the 2003 LDV 400 CONVOY D LWB
The 2003 LDV 400 CONVOY D LWB is a large car with a 2400cc diesel engine. 31 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It sits in the bottom 91% of 2003 cars for MOT pass rates.
With an average of 70,112 miles at 23 years old, LDV 400 CONVOY D LWB 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.
2003 LDV 400 CONVOY D LWB Fuel Costs
The 2400cc 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 2003 LDV 400 CONVOY D LWB?
Total estimated annual running cost is £2,395 (£200/month), broken down as £1245 fuel, £395 road tax, £55 MOT, and £700 predicted repairs. The higher repair estimate reflects the 65% MOT pass rate. Cars in this bracket tend to need work on suspension, brakes, and emissions components.
Buying a Used 2003 LDV 400 CONVOY D LWB
At 23 years old, the LDV 400 CONVOY D LWB 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 31 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 2003 LDV 400 CONVOY D LWB'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.
Higher Than Average Failure Rate
Watch outWith a 65% MOT pass rate, this model fails more often than most. Budget for unexpected repairs and get a thorough pre-purchase inspection.
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.
