Hi All
I have a 330ci coupe e46 2001 NZ new and the siren for the alarm is faulty - it is not as loud as it should be.
When I went for my most recent service the guys at BMW told me I need to install a new siren which will cost about $700 NZD.
What I am wondering is there an aftermarket siren that I can install to replace the BMW one?
The information is much appreciated.
