🚨 GUESS THE FAULT EP30 — FINAL CONCLUSION! 🔥
🛢️ ONE SMALL OIL DRIP… A MUCH BIGGER PROBLEM?!
Remember the mysterious oil coming from that component?
🔧 Mercedes Sprinter OM651.
We found engine oil inside the vacuum reservoir and investigated the vacuum pump.
⚠️ WHY DOES THIS MATTER?
Oil contamination can affect connected vacuum lines, control valves and other vacuum-operated components.
And there's something many owners don't realise…
🚨 THE VACUUM SYSTEM IS ALSO IMPORTANT FOR BRAKE ASSISTANCE!
🔍 THE RIGHT APPROACH:
✅ Identify where oil is entering the vacuum system.
✅ Check the vacuum pump and connected lines.
✅ Inspect affected components.
✅ Repair the source, not just the visible symptom.
💡 THE LESSON:
THE OIL DRIP WAS ONLY THE CLUE. THE REAL PROBLEM COULD BE HIDDEN ELSEWHERE!
