I have checked fault codes for Audi s3 p0332 p0333 and p0325 to p0328 and they all say the same

Question

Is there six different knock sensor and if so could they all be broken

Answer 1

You have 2 knock sensor only both are setting codes, one in the front near the cooling outlet housing and the other is at the rear block, when you set a knock code you check the basic, the cooling system that code cause a knocking noise, due to  a overheating condition, the oil level low to no oil would cause a rattling noise, a lean condition can cause a knock sensor code,
