Engineer mode for Moto E 2nd Gen?

[fkneg1]

Does anyone know the code for engineer mode for the Moto E 2nd Gen? I have found some codes online but they don't work.
I have an issue with the in-call volume being very low which I think I may be able to fix in engineer mode if I can get to it!

Welcome to Android Forums.

Have you looked at Tasker (sub-forum to this forum)? It has the capability of manipulating all 7 streams. Perhaps all you need to do is to set the In-Call volume to the maximum.

(An app that you installed may be playing with that volume.)
