Engine light on ( timing chain problem)

Hi- my mechanic diagnosed my engine light problem suggesting a stretched timing chain. the car runs fine no noises or any engine issues. Could this be a sensor problem or is the timing chain the real issue?

Timing chain stretched-balance shaft gear worn-tensioner stuck-no way this is a sensor problem unless you have codes that aren't 1200 or 1208 current or stored in MOTOR ELECTRONICS...

good luck

Thanks for the reply.

What is the easiest way to reset the computer so as to see if the light reappears?

OM642 stretch can be rather easily checked by anyone; open oil filler cap, you'll see tensioner shaft, if oil lubrication hole is visible, it's about time to change...

Thanks.
It seems fine to me, the problem now is how do I get the engine light off?

If the original fault that caused the light is not longer valid, light shuts off after 3-5 successful (fault free) starts....
