Fiat 500 constant alarm sound going off?
My car was stationary and I had my phone connected to the speakers on a call,
then all of a sudden the call ended and a deafening, loud horn noise (although
it wasn't the same sound as the horn) started and I switched everything and the
engine off and the noise was still going on. I did this multiple times to see what
was going on, but it did nothing and the noise wouldn't stop. I parked my car up
and switched everything off and left it for about 30 minutes whilst the noise was
still occurring. after about 30 minutes the noise had stopped so I restarted the
car and everything was perfectly fine. So I have no clue as to what was causing
this noise/what this noise was.
