Hi guys.
Looking for advice on how to fix the loose armrest on my 2013 Fabia Elegance please. I looked on the YouTube and can only find other VAG vehicles which are nothing like mine! 
any help most gratefully received, thank you in advance. 

Pretty new to Skoda and cars in general, so not quite sure what you mean by 'VAG vehicles'. So if my experience here isn't a help I do apologize.

Ive been wanting to mount an OEM armrest in my same year Fabia, so me and my ADHD brain started disassembling the centre console one day to figure out how to mount it. Its juts 4 bolts, likely hex keys like most things with the car. all you need to do to get to them is with the handbrake up (on) undo the bolt under the rear cupholder and lift the centre console up from the rear. you may have to remove some panels around the armrest base to be able to lift the centre console. Once you have lifted the rear of the console a tiny bit you'll be able to see the bolts. 

if the problem is with the armrest itself, and not where it mounts to the car I have to apologize again, as I haven't been able to learn more. 

Also If anyone knows where I can get an OEM, or OEMatching armrest it greatly appreciate tips.
