AdBlue delete on G30 is doable but make sure the tuner has experience with the newer SCR systems. Its more complex than older DPF deletes.
I did AdBlue delete on my G30 530d. The tuner disabled the SCR system in the ECU and removed the AdBlue injector. No warning lights, no limp mode. The car runs perfectly. Cost was about 500 EUR for the software solution. Just be aware this is not legal for road use in most EU countries and will fail emissions testing.
The G30 AdBlue system is more complex than older cars. Make sure your tuner has experience with the Bosch MD1 ECU in the B57 engine. Some tuners only disable the warning but dont properly disable the SCR system, which can cause issues down the road. A proper delete should disable the AdBlue dosing, the NOx sensors, and the SCR catalyst monitoring.
