Fuel injector replacement typically takes 1 to 3 hours, depending on the vehicle and how accessible the injectors are.
Costs can vary depending on your vehicle’s make and model and whether you’re replacing a single injector or a full set. On average, it can range from £150 to £500 or more, including parts and labour.
Driving with a faulty injector isn’t recommended. It can lead to poor engine performance, increased emissions, and potential engine damage if left unresolved. It’s best to address the issue as soon as possible.
Common signs of faulty fuel injectors include rough idling, poor fuel economy, misfiring, difficulty starting, loss of power, or the smell of unburnt fuel. You may also see the check engine light appear on your dashboard.
Fuel injectors are responsible for delivering the right amount of fuel into the engine’s combustion chamber. They help ensure efficient fuel combustion, smooth engine operation, and optimal performance.
No — deleting or blanking off the EGR valve is not recommended. While some believe it improves performance, it can lead to increased emissions, higher engine temperatures, and long-term engine damage. It’s also illegal in the UK to remove or disable emissions control systems, and doing so can cause your vehicle to fail its MOT and result in fines or penalties. Keeping your EGR system functioning properly is the safer, more reliable choice.

While it may be possible to drive for a short time, it’s not recommended. A faulty EGR valve can cause long-term damage to your engine, reduce fuel efficiency, and increase emissions. It’s best to get it checked and replaced promptly.
Common signs of a faulty EGR valve include rough idling, poor acceleration, increased fuel consumption, engine warning lights, and failed MOT emissions tests.
The EGR (Exhaust Gas Recirculation) valve helps reduce harmful emissions by redirecting a portion of exhaust gases back into the engine’s intake. This lowers combustion temperatures and reduces nitrogen oxide (NOx) emissions.
It’s a good idea to get a diagnostic check at least once a year as part of regular maintenance. Additionally, if you notice any unusual symptoms or if your check engine light comes on, schedule a diagnostic service promptly.
