@ascocarsltd: Customer came in because the rear of the Mercedes S-Class was only blowing hot air. 🥵 Plugged in the diagnostics… no fault codes. 👀 This is where experience takes over. After carrying out further testing, we found the fault ourselves — a faulty A/C valve 🔧❄️ Not every problem is stored in the computer. Sometimes you have to investigate, test, and understand how the system works. Have you ever been told, “No fault found,” even though something was clearly wrong? 🤔👇 #mercedesbenz #viralvideotiktok #london #amg #Summer
