E53 x5 3.0 hazard light flashes while parking?

[hellgrace5]

Hello!My e53 x5 hazard lights keep on flashing while I left it parked outside for like an hour.Some say it's the crash sensor,crash relay or the hazard light switch.Does anyone have a solution for this?Addon: forgot to mention that I bumped the car and both front PDC sensor dmg and the hood got bent alittle. Pdc sensor not yet install but hood and bumper is restored to shape. Can it related to PDC sensor or?

Hello!
My e53 x5 hazard lights keep on flashing while I left it parked outside for like an hour.
Some say it's the crash sensor,crash relay or the hazard light switch.
Does anyone have a solution for this?

Addon: forgot to mention that I bumped the car and both front PDC sensor dmg and the hood got
bent alittle. Pdc sensor not yet install but hood and bumper is restored to shape. Can it related to PDC sensor or?

since u have bump the car, better plug-in check for error code n diagnose from there to save time n money, might be just a relay

Diagnose already only get fault from PDC front middle left & right sensor.
Does it have something to do with my hazards randomly flash when parked?
