Hello guys!
I am having some problems with my Mitsubishi ASX. I am having Check engine oil warning. I have changed oil and filter and is at a good level, I get no error codes when scanning and I have tried reset service. Nothing works, does anyone knows what it can be?

And what is this sensor/switch for, located in the front on lower part of the engine.

when the light came on did you check the level then?
or did you just drain it and refill then check the level?

if the engine was overfull before and the warning message was" check engine oil"
then just draining will not send the message away. You need to reset the oil level counter using a scantool




I can see from your picture it is a diesel. do you have a split in the big air pipe going into the throttle body? The big thick black one to the right of your photo?

The oil was a bit overfilled and dirty so I changed oil and filter and it’s at a good level now, the light was on before the oil change too and I’ve scanned for error codes with an ELM327 and there ain’t no codes and tried to delete anyways and nothing happens.

I’ll check the pipes for leakage tomorrow

It sounds like your DPF is not regenerating. Do you do lots of short trips?

Have done recently over the past year with the UK lockdowns prior to that was doing reasonable length commutes daily. Surprised not to have DPF warning as well though that I would have suspected to have seen.

Short journeys is a killer for DPF systems. When the Rengeneration fails the extra fuel washes past the piston rings into the crankcase thinning out the oil.

So yes you will need to change the oil, but to turn the warning off you will need a scantool that can perform special functions, and not just code erase and read.

Dealers obviously have this, and independents will have a generic scan tool that can do this, but in my experience they do not know how to.
