Ooh, that's a new one??Not running, not even the key in, just bonnet open.
Not coming from just behind and below the battery by any chance where the alarm sounder is located?Not running, not even the key in, just bonnet open.
Definitely sounded fip side but I've had to go out, just got back. I'll have a better listen tomorrow but, yes, that alarm sounds feasible as the ignition was off....maybe valve block too?.Not coming from just behind and below the battery by any chance where the alarm sounder is located?
Valve block is possible. The B-Bus sounder has an internal battery that dies and that can cause it to buzz.Definitely sounded fip side but I've had to go out, just got back. I'll have a better listen tomorrow but, yes, that alarm sounds feasible as the ignition was off....maybe valve block too?.
