I noticed a few weeks ago that when triggered my alarm only causes the hazards to flash with no sound. I removed the coolant reservoir yesterday and removed the sounder unit. Opened up to find it is the victim of water ingress and is corroded.
Anyone have a replacement unit in good condition? I believe the part number is YWK000040 or YWK000041.
I have also heard that certain BMW sounded will work but not sure if that would cause problems due to the electronics being different or not?
