Im not an expert in emissions testing but pretty sure it still needs CE certification testing. The module shouldnt cause any problems providing that the firmware for the transmitter is configured properly, and is placed sanely in the enclosure, but the entire product must still undergo the relevant testing for 2.4GHz emitters.
Just because you use a certified module doesn't give you a free pass.

To be fair, it's unintentional radiator testing that's required, rather than everything the module had to go through as an intentional radiator. So, it is a "free pass" for nearly all of it, and a much cheaper one, since you don't have to use a costly FCC accredited lab.
Modular Approval is an FCC thing only. CE doesn't have it.
It does still need CE certification and emissions testing. I’m guessing they didn’t do that and it will be fine because they only sold 2,500 units.
Technically it doesn't - it just needs to be compliant.
It is completely left up to you how you are going to demonstrate this if they ever come asking for the paperwork proving this. This can be a certification by an independent testing lab, documentation from in-house tests, or perhaps even documentation proving that it is compliant by design.
