Your vehicle’s fuel injectors play an essential role in delivering the correct amount of fuel to your engine, helping it run smoothly, efficiently and reliably. Over time, injectors can become blocked, develop leaks or stop delivering fuel correctly, leading to poor performance, increased fuel consumption and potential engine problems.
At Auto Service & Tuning Centre Hitchin, we use the advanced ASNU Classic GDI fuel injector testing system to accurately assess injector performance, identify faults and determine whether existing injectors can be cleaned and maintained rather than replaced. This specialist technology helps us deliver precise diagnostics, cost-effective solutions and improved vehicle efficiency.
Based in Hitchin, Hertfordshire, we also offer specialist fuel injector testing for other garages, allowing workshops without dedicated testing equipment to benefit from our advanced diagnostic capabilities.
