Trunk wont stay closed - 2005 Audi A8

Sounds like you have a bad switch in the latch. You can try spraying it with contact cleaner and operating the switch several times. But most likely you will need to change out the bad latch.

Is the boot light staying on? If it is then the switch is faulty!

trip the lever on the latch and release it.

if the latch is broken you need to get a new latch.

undo the trunk release latch to see if trunk stays shut. if it does then check for stuck release button or short to ground on that circuit.

I have a 2008 chrysler300 and i had installed a system in it and noticed that my trunk kept popping open and i doubt its the subs because i only have 1 10 inch sub and when im driving it randomly pops open and i dont know what the problem is, can anybody help with this situation?

Please make sure your keys are not in the trunk because there is a safety mechanism that will not allow the trunk to stay closed if the keys are detected in the trunk. The other issue will be if the hold down mechanism is not pulling the trunk completely closed once the trunk engages the lock. You will then have to have it serviced to make sure the pull down motor is operating.

the piece on the body wants adjusting

use duct tape to hold the lid down.....just kidding. insert the key into the lock and see if it will UNLOCK.

replace the latch, the spring breaks in them and causes this problem
