where can i find the power sounder ?

The power sounder is in the passenger side wing (assuming your car is right hand drive)
You have to remove the wheel then the plastic inner arch liner to get at it. It's a sealed unit, you used to be able to cut them open and put in new batteries, but I dont think you can get the batteries any more.
If you fit a new unit I believe it will have to be set up by a dealer or an independent with dealer level diagnostic equipment (tech 2, abcom etc.).
