@alcomoto: 🚗 This Audi arrived running incredibly rough… and the diagnostics told the story. The engine was misfiring badly, the idle was extremely uneven, and the fuel pressure readings were fluctuating far more than they should. Rather than jumping straight into replacing parts, Alex worked through the diagnostics step by step to find the root cause. After analysing the live data and carrying out further testing, the investigation led us to the injectors. They were removed and sent away for professional testing to confirm the fault before any repairs were carried out. This is exactly why proper diagnostics are so important. Modern vehicles can display the same symptoms for several different faults, and replacing parts based on a guess can quickly become an expensive mistake. Watch the full video to see the diagnostic process from start to finish and why taking the time to diagnose a fault properly always pays off. Follow along for Part 2, where we’ll show the test results and the repair that gets this Audi running smoothly again. #Alcomoto #Audi #AudiDiagnostics #EngineDiagnostics #Misfire
