I just noticed this yellow warning light. It is steady on as I drive. Any reasons to worry?

My Tiguan is TSI 125, old fashion Auto, 2010 model. It has 55,000 km - last service at 50,000 km a year ago.
Interestingly, a few days ago - before the engine light started - I had a low oil light. The dipstick was showing Min, so I added 1/2 litre and it is now midway between Min and Max.
Could there be any link between the two?

Is it possible that engine light is just a routine emission control warning? There are lots of YouTube videos how to reset this light (not for VW)

Any advice would be appreciated.
