An issue found in almost half of all vehicles on the road could cost used car sellers up to £400 if not taken seriously, according to experts.
Not fixing issues with a car when they first appear may help save pennies in the short term but accumulating issues is likely to backfire.
A dashboard warning lights system showing a catalyst of issues is not going to sell meaning road users will have to pay out for a costly service.
Modern cars are packed with sensors in almost every area with the dashboard warning light system showing which areas might be suffering from issues.
This can be anything from problems with a car’s power steering, exhaust, engine failures or tyre concerns.
Steven Edwards, editor at used car platform MOTORS, has claimed the price of a service is likely to vary based on the type of vehicle owners have with some set to pay up to £400.
He explained: “The brake, engine, airbag, coolant and low tyre pressure warning lights are just a few of the dashboard symbols drivers will be familiar with.
“While warning lights should be addressed with or without you selling your vehicle their presence could seriously affect a car’s value. Taking your car in for a full-service before putting your vehicle up for sale will allow you to address these issues and get them fixed – boosting the value of your car and reassuring buyers.
“Unlike an MOT, which checks a car’s roadworthiness, a full-service checks over the various aspects of the vehicle from electrics to tyres, identifying any underlying problems including dashboard warning lights.
“The cost of a full service will depend on the size of your vehicle, with smaller models averaging around £170 and larger makes hitting the £400 mark.
“Remember to keep a physical paper copy and receipt for your service should you need to produce it on the day of sale.”
It comes after previous research from dealer group Robins & Day found that a whopping 46 percent of adults ignore dashboard warning lights in their car.
One-third of those surveyed said they pushed back getting issues looked at due to the likely cost of expensive repairs.
BookMyGarage, the leading comparison site for service checks and repairs, has put the average cost of a full service at £182.40.
However, they warn this could rise towards £280 depending on the car’s engine size.
A service will take around three hours to complete and will usually cover almost all the vital parts of a vehicle.
Some services will also include some minor repairs such as the replacement of oil and air filters and possibly spark plugs.
