Injection à contrôler / Antipollution à contrôler – Renault Koleos bridée P012B #antipollution

🔧 Renault Koleos 2012 – Loss of Power / Code P012B7A 🔧 Hi everyone, it's LARS DIAG AUTO! In this video, I show you the complete diagnostics of a 2012 Renault Koleos suffering from a loss of power: the engine won't go above 3000 rpm, with the following messages on the dashboard: "CHECK ANTI-POLLUTION SYSTEM" "CHECK INJECTION" And the engine light is on ⚠️ 🔍 After testing the diagnostics, a P012B7A fault code pops up: "Leak detected in the turbocharger system" And for good reason: the intercooler hose had come loose, causing a drop in turbo pressure and the turbo to go into degraded mode. In this video, you'll see: ✔️ How the diagnosis was performed step by step ✔️ How to spot a leak in the turbocharger system ✔️ Why this type of fault causes engine throttling 👉 A simple fault, but one that can lead you to believe a much more serious problem if you don't look in the right place. 💬 Remember to like, comment, and subscribe so you don't miss any upcoming diagnostics!
