I have the shock sensor installed (by the dealer before pickup). I have noticed a rattle from the passenger side of the car. Near the hinge and the floor. I'm thinking that its the alarm shock sensor. I took the plastic cover off to check and there is a fair bit of movement in the sensor.

Any suggestions?

I'm thiking of getting some foam and stuffing it between the shock sensor and the plastic cover. I'm thinking that those are the two bits rattling.

But if you have a better idea, or a warning against doing this, then I'd love to hear 'em.

Thanks in advance.

 

Are you sure it's the shock sensor?
