The most serious issue you have is a leak in the evap or boost system - lots of places it could be - diverter valve, boost hoes leak, evap pipework, cam cover gasket, etc.
The P0243 is N75 valve & P0441 is the carbon canister - these are lesser issues than above, on mine these would only flag up once a month. Of the 2 items, one is not working, generating the 2 faults - easy DIY fixes, try a canister, cheap ones from jungle web site or ebay are fine, if the faults are still there replace the valve - Bosch make these for VW, just get a genuine Bosch replacement.
Couldn't hear anything in the vid, but the drive belt tensioner is moving in and out quite a bit as if something is loading up the belt every other second - normally these will sit steady. This could be the tensioner, AC or Alternator pully binding up.
