Engine /EML/ diesel particulate filter /DPF/ light on just check fault code if P252F fault is set only the problem is engine oil level is too high what is calculated by engine ECU NOT with engine oil level sensor is not fit in the engine so don’t start looking the location, check the engine oil level manually, if overload better to replace with oil filter. I see a couple of cars that it was overfilled with 6-7 litre fuel, so it needs attention. Recommend engine oil 5w30 C3 /C3/ is protect the DPF system.
Why is the level growing up? The DPF is not regenerating properly for some reason and keeps spraying fuel in. When the DPF start regenerating it needs extra heat and the spray of some fuel helps the DPF. Normally the Mitshubishi technician after the service, resets the engine oil level calculation /is on the service list/ to 0 so if you run to the local garage is not sure if is done the reset.
A couple of things why not regenerate the DPF, driving condition is not met is in the owner’s manual, the fuel level is too low recommend half tank fuel, any fault code set, some DPF temp sensor is not working correctly is have 3 in so check the data list have to be close all 3 sensors if 1 to far out is a fault, other main things the EGR valve not always get fault code and electric motor side check the data list any different between the ECU what tell and the real EGR movement.
How to reset the engine oil level? With MUT diagnostic machine go to engine -special function-initialisation-exchange engine oil level reset to 0 and is done.

[…] Engine light on DPF light on, a couple of problems with them when don’t have proper service on the vehicle. Service interval is 12500 Miles or 12 mouth. P252F fault code engine oil level too high is calculated with engine ECU, not with a sensor that comes when not reset after service or has any problems with DPF or other system. We can check the real mileage/kilometres with a diagnostic machine, is in the engine ECU and what is not writable but in the odometer is writable so have a point to check, what I see is the highest clocked vehicle it was 100K miles.
