Didn't know there was an alarm in the car that my other half is driving...

now issue....

it's going off and then resetting and going off continuously while she is driving...

this is in a 1988 560 sel

help....

just unplug the alarm module.

or snip the power to the siren.

x2 what Porkface said. Just unplug the control unit under the passenger footwell. Don't cut the wire to the siren. The antitheft alarm may not go on, but your 4x flashers will still flash.
