About the 1998 MERCEDES HYMER

The 1998 MERCEDES HYMER is a large car with a 2800cc diesel engine. 40 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 21% of all 1998 cars for reliability.

With an average of 78,746 miles at 28 years old, MERCEDES HYMER 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.

1998 MERCEDES HYMER Fuel Costs

The 2800cc 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 1998 MERCEDES HYMER?

Total estimated annual running cost is £2,045 (£170/month), broken down as £1245 fuel, £395 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 83% pass rate. Keeping on top of servicing will help avoid surprises.

MERCEDES HYMER Reliability Trend

Buying a Used 1998 MERCEDES HYMER

At 28 years old, the MERCEDES HYMER 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 2020 model has the highest pass rate at 97%. Note: with only 40 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

Based on the 1998 MERCEDES HYMER'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.

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.
