Alarm sounding and volume?

Post by Warrior » Mon 12 Jun, 2017 23:03

For the first time in 5 years of ownership my Z3 alarm went off several times this morning.
No strong winds etc.,

Any suggestions?

Check the left rear well in the boot for water. That's were the tilt sensor lives and it is right below the aerial. It the aerial grommet is leaking, then it fills the well with water.

The other common alarm cause is the bonnet/hood switch.
