Did you open it to check what could be wrong? Maybe the connection of the capsule to the circuit board is not good, it can be as simple as that.
You need Torx T8 to remove the 3 screws and slide the basket out carefully not to tear the cables and that's it. You can post photos here. They have replacement capsules for sale just in case.
BTW I got in touch with BaiFeiLi store on aliexpress and alibaba, they have been pretty nice and offered me to send a spare capsule if I pay for the shipping or with an other order. They also told me they will check with the assembly line to prevent that. I was thinking of getting a BaiFei Li V5, they seem to be really smooth and great for vocals.
I tested and measured the response of the 414 with the fingerprint and the 4 other I have with REW and there was almost no difference between all of them.
I paired some to make stereo matching drum room microphones and overheads.
This is the response I got from all the BFL. The curve is because of my speaker/room response and mic placement but they are really close to each others.

I have already inspected, nothing convincing, but indeed the work is not neat inside...
They clearly tailored the response of this mic to a C414 target. Manufacturing consistency and reliability would be the only considerations.
Wow! They didn't wear gloves during assembly? Someone at Bai Fei Li needs to take Quality Control 101.

That would be great but it would require a double sided capsule as well. The stock one is single sided.

I haven't posted on this fine site for some time, but wanted to add my opinion here - yes this I the case.
The V5 is the pick of the bunch according to the folks I spoke to from BFL.
The V5 is a very velvety sounding mic on vocals.

I received 2 x 25mm versions of this mic the other day (already had the 34mm version).
One of the 25mm versions is about 4db lower than the other (noise floor seems about the same though).
I contacted them (Enping Shiyinzhe Electronic Technology Co.) to let let them know about the difference and suggested that they should sell matched pairs. To my surprise, they got straight back to me to say that if I request matched pairs at the time of ordering, they will supply them matched.
Both types are very nice sounding microphones - really amazing value for money. The 25mm has a very nice sound - somewhere between a traditional SDC and LDC.
Any ideas why one mic would be 4db quieter than the other?

I understand that you have 2 microphones with 2 capsules, theoretically identical and one of the microphones has a lower output signal.
Did you reverse the capsules in the microphones?
Maybe one of the capsules has less sensitivity.
By reversing the capsules maybe the output levels would equalize, it's worth a try.
Or, Maybe the cause is that the electronic circuit of one of the microphones has lower sensitivity, for example one of the input jFETs has a different Idss,
or polarization voltages of the capsules are not equal
