The airbag A-pillar trims were designed to be single use only, so the plastic attachment 'lugs' break off when you pull them away from the metal bodywork pillar
BUT..... if you have a set of security torx allen keys (available from Halfrauds), you can just get in behind and very carefully release the retaining straps from the trims, allowing them to be removed, then the lug that normally breaks can be carefully released from the spring steel clips in the pillar
Sorry I don't have any pics to explain this, but I've removed and refitted them a few times, so it is possible.
The B-pillar trims just need the airbag badge prizing out, then from memory, are removed like a conventional (non airbag) trim
