🔧 GDI Petrol Injector Testing at Llandow Tuning 🔧

Check out the results from our ASNU test bench! Notice how the second injector from the left (cylinder 3) isn’t working – this is something you won't easily diagnose in the car without specialized equipment. In fact, replacing it without proper testing is mostly guesswork.

If you drive a TFSI EA113 or TSI EA888 engine, you’re likely familiar with misfires. It’s not just a VW thing – it’s a common issue with GDI (direct injection) engines. 💡

Many customers come in for Walnut Blasting to clear carbon buildup from the inlet manifold, which is a great service! However, carbon isn’t always the culprit behind misfires. While coil packs and spark plugs are often blamed, our top suspect? The fuel injectors.

At Llandow Tuning, we’re the ONLY garage in Wales with multiple ASNU benches with the ability to test all types of petrol injectors: Port, GDI, and Piezo injectors. ✅ If your engine’s not running smoothly, let us take a closer look before you replace parts blindly!
