🚗 Mercedes & European Vehicle A/C Leak Diagnosis 🚗
This beautiful Mercedes S550 came to us with an A/C system that was slowly losing refrigerant. The challenge? The leak was so small that traditional UV dye testing showed no visible signs of a leak anywhere in the system.
🔍 After a thorough inspection, our advanced electronic refrigerant leak detector (sniffer) quickly identified the source of the problem — the A/C evaporator core hidden deep inside the dashboard.
⚠️ On many Mercedes-Benz and European vehicles, replacing the evaporator is a major repair because the entire dashboard must be removed to gain access. As you can see from these photos, this is not a shortcut job.
✅ UV dye showed nothing due to the extremely small leak
✅ Our professional leak detection equipment pinpointed the issue immediately
✅ Complete dashboard removal required for evaporator replacement
✅ Proper diagnosis saves time, money, and unnecessary parts replacement
At Duane’s Dealer Alternative, we invest in the latest diagnostic equipment to find problems that other methods can miss. When it comes to Mercedes, BMW, Audi, Lexus, and other European vehicles, accurate diagnosis is everything.
