Compare Hyundai I20 fuel injection system repair quotes from specialist garages

The i20 is a practical, efficient and stylish small car, making it a popular choice for urban commuters. There is a more exciting side to this model, too, because it is used as the basis for Hyundai's rally car, competing in the World Rally Championships (WRC).

At the 2023 WhatCar? Awards, the Hyundai i20 N was crowned 'Hot Hatch of the Year' - a highly sought-after title - earning praise for its "brilliant body control and grip". Two years before, it was also named 'Car of the Year' at Top Gear's annual awards. The most recent generation of the i20 is exceptionally reliable; in earlier models from 2009-15, watch for signs of clutch wear and blocked DPFs in diesel engines.

When you accelerate, your car's throttle valve opens, and the fuel injectors spray fuel. How and when this fuel mixes with air depends on what system is used. Petrol engines use an indirect system, where fuel and air mix before entering the combustion chamber, while diesel engines use a direct system, where air and fuel only mix once in the chamber.

Unfortunately, fuel injectors can become clogged over time, in which case you should book a petrol or diesel injector cleaning service or buy a fuel injection cleaning kit.

Signs you may need to have your fuel injectors cleaned include engine misfires, poor fuel economy, rough idling, engine stalls and leaking fuel.

If cleaning the injector system doesn't work, you may need to book a fuel injector repair or fuel injector replacement, depending on the severity of the problem. A fuel injection specialist can offer advice specific to your vehicle.
