A Skoda Octavia 1.4 was brought into Squad Workshop, a highly rated specialist car workshop in Singapore, with a strong fuel smell coming from the engine bay. Upon inspection, our technicians confirmed a fuel injector leak, which is a serious safety concern due to the risk of fire.
Skoda Octavia 1.4 – Fuel Injector Leak Repair & Walnut Blasting at Squad Workshop
✔ Fuel Injector Leak – Immediate Safety Risk
The vehicle was advised to be towed to avoid driving with raw fuel leaking onto hot components. Our diagnostic confirmed injector seal failure.
We installed injector repair kits for all four injectors to ensure proper sealing and safe fuel delivery.
✔ Walnut Blasting – Severe Carbon Buildup
Despite low mileage, this Octavia had heavy carbon buildup caused by frequent short-distance driving. We performed a full walnut blasting and intake valve cleaning to restore engine airflow, improve fuel efficiency, and prevent misfires.
✔ Final Checks & Safety Assurance
After repairs, the engine was tested for leaks, fuel trims were verified, and the vehicle was returned with smooth idle and restored performance.
At Squad Workshop, we specialise in Skoda and VAG vehicles, delivering professional repairs, safety-focused diagnostics, and transparent recommendations. If you smell fuel or experience rough idling, have your car checked immediately.
A strong fuel smell usually indicates a fuel injector leak, cracked seals, or raw fuel escaping from the fuel rail. This is a serious fire risk and requires immediate inspection.
No. Driving with leaking fuel can ignite on hot engine components. We advise towing the vehicle to prevent fire hazards.
When one injector seal fails, the others are often close to failing. Replacing all four ensures balanced fuel delivery and long-term reliability.
Short-distance driving prevents the engine from fully warming up, causing carbon to build faster. Direct-injection engines like the Octavia 1.4 are more prone to this.
Walnut blasting removes stubborn carbon on intake valves, improving throttle response, fuel economy, and engine smoothness.
