Poly bushes are notorious for squeeking, if its a daily driver I would, as Paul70 has done, go with the Clubsport S bush which has smaller voids in to still allow the bush to flex but reduce any excessive movement.
I think the part number is 81A 407 183 having been recently superceded.
Or another option is the TTRS bush which is solid rubber 8S0 407 183B IIRC.
