🚗 Mitsubishi Triton 2018 — DPF warning follow-up.
Firstly, everyone was correct in their answers.
The fault ended up being a split boost hose.
Because the boost hose had split, the vehicle wasn’t able to complete a proper DPF regen. When the car attempts a regen but can’t carry it out correctly, it can lead to diesel dilution in the engine oil, causing the oil level to rise and overfill the engine.
Once the DPF light comes on, the vehicle will no longer perform a regen on its own — so it needs to be diagnosed and repaired properly.
In this case, finding the actual cause was the important part. A DPF warning doesn’t always mean the DPF itself is the problem. 🔧
