You have an intermittent engine fault.

You can't cure this by changing filters, or lots of stuff that isn't related to the fault.

You need to see what fault is bringing up the warning light and the tool to do that is Lexia tool (info here).

The lexia tool will give you the code and it's meaning, use this to diagnose the fault and you can then at least look into the right part of the engine that needs attention.
