In this video I show you how I repaired the alarm siren on my E70 BMW X5.

First I try coding the car to increase the volume with no luck.

I then take a look at the siren itself and discover a problem with it.

We are using the INPA software suite to do this. Specifically NCS Expert.

You can find the INPA cable online at places such as Amazon or Ebay. Search INPA Cable K+D Can.
