BMW Injector Testing & Replacement in Galway
Misfires, rough running, hard starting or smoke? Faulty injectors are a common cause on both petrol and diesel BMWs. We test your injectors, replace only the faulty ones and code new injectors to your engine with BMW-specific software.
What do fuel injectors do?
Injectors spray a precise amount of fuel into the engine at exactly the right moment. When one leaks, sticks or sprays unevenly, the engine misfires, smokes or struggles to start. Modern BMW injectors are matched to the engine with a correction code, so new injectors need coding with BMW-specific software to run properly.
Petrol BMWs
Misfires, rough idle and engine warning lights.
Diesel BMWs

Could it be your injectors?
Pick the symptom closest to yours to see the likely cause and the usual repair.
Faulty injector
Likely cause: an injector that sticks, leaks or sprays unevenly, so one cylinder is not burning fuel properly.
Usual repair: injector testing, then replacement and coding of the faulty injector.
Leaking injector
Likely cause: an injector leaking fuel or pressure, making the engine slow to start.
Usual repair: injector testing and replacement.
Poor spray pattern
Likely cause: an injector over-fuelling or spraying poorly, especially on diesels.
Usual repair: injector testing, then replacement as needed.
Injector seal leak
Likely cause: a leaking injector seal letting combustion gas escape, often heard as a chuffing or ticking noise.
Usual repair: injector removal and new seals and washers.
Leaking injector
Likely cause: an injector leaking fuel. A fuel smell should always be checked quickly.
Usual repair: leak check and injector or seal replacement.

BMW injector FAQs
Yes. Modern BMW injectors have a correction code that must be entered into the engine computer so each one delivers exactly the right amount of fuel. We code them with BMW-specific software.
Not always. We test them to find which are faulty and usually replace only those. We will advise if it makes sense to do more.
Age, wear, poor fuel and carbon build-up can all cause injectors to stick, leak or spray poorly.
A chuffing or ticking noise near the injectors is often a leaking injector seal letting combustion gas escape. It needs new seals before it causes more damage.
