There may even be an airbag relay cut off..
there was on my EK4.. like when you unplug the relay the airbag is automatically switched off..
but as said disconnet the battery..
You'll need a torx screx head to get them off they are not philips or flat head bolts..
Best way i found was to get a torx head screw driver and then use mole grips on them as i could not get the bolt to break with a screw driver handle i needed leverage..
P.S haynes manual's will answer alot of basic questions to do with things like this. its always worth while to get your hands on one...
