Fuel Injector Repairs – Brentwood

Fuel injectors deliver precisely metered amounts of fuel into the engine’s combustion chambers. When they become dirty, worn, or faulty, that precision is lost, and the effects show up across the car’s performance, economy, and emissions. It’s a problem that tends to develop gradually, which means it can go unnoticed until it’s causing real issues.

Symptoms of a fuel injector problem

• Rough idling or misfiring, particularly from cold
• Increased fuel consumption
• Hesitation or stuttering under acceleration
• A strong fuel smell, especially after switching off
• Engine management warning light

Injector issues can mimic other faults, so accurate diagnosis is important before any work begins.

What we do

Depending on the condition and nature of the fault, there are different routes available. Injector cleaning, either through an in-fuel additive treatment or a professional ultrasonic clean, can restore performance where the issue is contamination rather than mechanical wear. Where an injector is genuinely faulty, replacement is the right answer, and we’ll always explain which approach is appropriate and why.

We use quality parts across all injector work, and every repair is covered by our standard 24-month warranty on parts and labour.

If your car has been running roughly or your fuel bills have crept up without explanation, it’s worth having the injectors assessed. Contact Mercury Car Centre in Brentwood to book a diagnostic check.

Mercury Car Centre is a Bosch Car Service centre and a member of the RMI and IMI. We’re also registered with Trading Standards, so you can book with confidence knowing we’re held to recognised professional standards.
