Swirl Flap Motor

First of all , hello fellow Skoda owners!

Now let's talk about my problems!   

Few days ago i used autocom to try to find out what's wrong with my airbag and i also saw this:
19559 Swirl Flap Motor Defect

Check engine bulb is not on while the engine is running (bulb works perfectly) , i haven't experienced any issues while driving the car , but i saw two or three times that idle is jumping a bit , between 9xx to about 1050rpm.Now nothing weird happens and I think fuel consumption has not changed.

So, the question is, could this damage the engine and if that's the case how can I solve the problem, or it's not a problem at all and I should not think about it anymore?
It would be great if someone could tell me what to do with other two problems i have:
00588 Airbag Squib Circuit (Drivers)

18027 Glow Plug Relay Coil Open or short circuit to Ground

Thanks in advance!
