I need a new alarm siren at £85 but also have to pay for it to be coded to the car, why? The siren fits many other cars so why does it need this, just puzzled.
I had a new siren fitted today, it was the newer version that chirps when it is armed or disarmed. It also had to be coded so I could not fit myself which I am more than capable of doing.
I rang a genuine dealer to buy the siren and they said it must be coded to the vehicle.
I rang a local Mercedes specialist who also said the same thing! Well it's fitted and working and all error codes deleted that were created due to the faulty siren and actually the knackered car battery that I also replaced a week earlier. It cost £175 and all is ok at present.
