P3 Gauge install in a G80 M3 Competition 

It will be one of the coldest Christmas recorded here, at least 50! Very excited to see you guys soon.

So far we haven't had any issues with the gauge and alarm going off. Reach out to our sales team and they can help look into that for you.

Spoke to the guys at P3 and they have advised the following: The alarm is getting triggered from the OBD2 monitor in your car checking the network once the car is locked. (the car doesn't want to see any foreign traffic on the network) A few modern cars do this although most do not. There are 2 ways around this - You can code it out with Bimmercode (for BMW) or an equivalent software. Here's a video showing how to do that - m.ru-vid.comholknjAN4ao?feature=share You can cut the red power wire on the gauge's harness and run it to a switched power source. The OBD2 port has constant power (meaning it has power all the time) If you do this you will also want to change your power control option from "Pco.A" to "Pco.S" in the config menu.
