If your red LED immobilizer light stays lit when the car is running or your car is blowing the anti-theft fuse, you have a bad siren.
Over time, the battery in the siren fails and destroys the circuit board inside.Replacing the siren should give the system another 20 years of life.
Our sirens are new OEM Bosch sirens that have been reprogrammed to include the original Ferrari compatible data.I also replace the batteries with new ones, as many of these batteries are already failing off the shelf.These sirens will behave identical to the dealer part for a fraction of the cost.
Compare to Ferrari part number 177148 which is $1,000 at dealer prices.
