Just bought the car 2016 octavia 2.0 tdi se l, looking at the accelerator pedal is a plug missing  , also the foam lower cover mis sing aswell (tried to find this part on internet with no results) does anyoane has any clue?  

Not much to go on here, but I've looked at my accelerator pedal and it has two plugs connected where you only have one plugged in. I think you'd see the plug hanging around and you would have to unclip it from the socket with some effort. So I doubt it's missing anything. 

 

I wonder if it could be different due to different specifications. Mine is the Dsg,  so automatic. 

 

you might not have a lower foam cover at all if you have a knee airbag, there is a softer plastic cover below mine where the airbag module is situated. 

Mine is manual. At least I want to cover again that area but it's hard to find that cover on market

Dont go covering the open purple connector above it will you!

 

I would say that an open connector with exposed male pins does not seem correct unless there are no wires connected to them.

2015 manual1.6tdi and mine is the same as yours Theleffect, nothing plugged into the white connector.

That looks like the control unit the front and rear parking sensors plugs into.  I've got front and rear sensors. It looks like you must only have rear parking sensors.
