Why does my car making a ticking noise when it's cold?

Question

For weeks, my car has made a ticking noise when it's cold. Sometimes it's very loud, sometimes it's only quiet, but I haven't been able to have anyone listen because obviously the car is warm by the time I get to any mechanic.

The noise sounds a bit like something hitting the spokes of a bicycle wheel as it goes round.

Yesterday evening, the check engine light came on, and I very much suspect it is to do with what is causing the ticking but there's no way I can get to a mechanic for a while and I need to know if the car is safe to drive.

I drive a 1.2 Kia Rio btw.

It sounds like a hydraulic lifter which operates by the engine oil & oil pressure.  If it is operating incorrectly due to low oil pressure or a partial blockage, it will make a light clacking or tapping noise that speeds up as the engine RPMs increase.  As the oil heats up inside the engine, the lifter begins to operate properly.  Check your oil level.  Also, check for dirty oil.  Then ask your mechanic.

have you checked the oil level?
on some cars, the oil light only comes on when its empty and damage has already been done.
the ticking can be a sign the engine oil is running dry
