π Coolant loss with no obvious leak? It might not be as simple as topping it up...
This vehicle came into Red Oak Garage with a coolant loss issue that wasn't immediately obvious. After carrying out a full inspection, we traced the fault to a failed EGR cooler.
The internal failure was allowing coolant to leak into the exhaust system, which in turn had begun to block the Diesel Particulate Filter (DPF). Left unresolved, faults like this can lead to reduced performance, repeated warning lights, costly repairs and, in some cases, serious engine damage.
This is why proper diagnosis is so important.
Rather than replacing parts based on assumptions, we identified the root cause first. By finding the original fault, we can recommend the correct repair and prevent the same problem from returning.
If you've noticed: π§ Unexplained coolant loss
π§ White exhaust smoke
π§ Frequent DPF regenerations
π§ Reduced engine performance
π§ Engine management or DPF warning lights..it's worth having your vehicle checked before the issue becomes more expensive.
At Red Oak Garage, we use dealer-level diagnostic equipment alongside years of workshop experience to diagnose faults accurately and repair them properly the first time.
