Narrative:
We took aircraft X in ZZZ with MEL 30-3. Engine cowl valve light on bright with switch off. This had been written up earlier in the day and all maintenance procedures were reported to be verified and complete as noted in logbook and on the release. However, in cruise flight, I was looking at the MEL appendix section. In order for this aircraft to be operated in conditions above 10 degrees C, a modified cowl is required. Upon inspection of the cowl in ZZZ, it was unsure whether this cowl was actually modified or not. I called maintenance duty and they seemed surprised at my discovery, and insisted that this was a modified nose cowl. I described the cowl to them and at the time of this report, it seems that the cowl is unmodified, and I operated the aircraft X in conditions above 10 degrees C.
