E46 bump sensor

[Kurt Adv]

Where is it? My alarm goes off for no reason, I suspect the bump sensor, need to find it....

Have you checked the bonnet switch, it's normally the cause.

No, but thanks for the tip, will check it out.:ty:

it should be the bonnet or loose battery connection

 

[ET was here]

was also thinking, check the bonnet switch first

 

[Kurt Adv]

Checked the bonnet switch, seems ok....I activated the alarm, waited a while, gave the bonnet a few klaps, nothing. Does this switch get dirty inside? I will spray it with electrical cleaner....

I have the same issue.

i unplugged the switch so far but my car is in the shop so i cant say if it worked or not.

I jiggled the bonnet switch, sprayed some electrical cleaner in there, hasn't gone off since...
