If I do install this do you know if it will affect my BMW comprehensive extended warranty?
Also, as you know the alarm beep is so quiet, have people just added a louder 2nd siren or is there more to this than I'm thinking?
Thanks again for your help
I hope your sensor installation goes well.
I cannot comment on warranty status to be honestly.
Re: you can install aftermarket alarm if needed. I have not done that yet though it is sitting at my place.
