I was getting an error code about not being able to communicate with the alarm siren so bought one off eBay.
After clearing that code it hasn't come back but the new siren is VERY quiet, almost impossible to hear.
I assume something isn't right here? I read on the forum that it's quiet but at this volume it's pointless, you can't hear it 2ft away
Car is a 2003 2.0 TDI
Alarm module: 1K0 951 605A
