Trunk Lock Replacement
#51
AudiWorld Wiseguy
Hi! Looks like im having some issue with my trunk as well. it was fine in the summer but right now as we speak it isnt as cold yet. but anyways, it wont lock even if i close it manually or with the button. so basically it does not latch at all and wont lock.
it looks like just replacing the lock mechanism as mentioned here with that part number you posted should fix this issue? just want to make sure!
I have a 2004 A8L.
Please let me know! Thanks

Hy huys , im a newby here ,, need some advice , my audi a8 2004/5 3 0ltre tdi boot is not locking properly , audi advised to change the lock which i did made no difference , what happes is the motor brings the boot down but does not pull tight shut , the boot seems to lift back up out of position and is not locked correctly , shows up on the dash as open and my alarm security system then fails as the boot is reg opened ? do i need to change the motor which opens up but weakly closes on the button but then the problems start ?

The soft close mechanism has failed. Most likely a broken spring. See here on how to fix and let us know how you get on.

I don't understand what you mean? Have you confirmed that when you manually latch the trunk latch, the strike pin mechanism is moving down or not? If not, have you been able to ascertain if the spring is still in place in that mechanism?

yes Dave the lock pin goes down , when i press the button to close , the boot lid comes down starts to lock then the lid raises about a quarter of an inch , on the right hand side , then goes down but still registers as open ? and the alarm system will not function , the diagnostic test at audi said change boot lock , i did , still got the same problem ? however it has once or twice rectified itself only then to go back to not working correctly

I wrote up a quick fix for the trunk lock issue that causes a lot of grief and is relatively easy and inexpensive to fix.

<p>This resolves issues with having to slam trunk to get it to latch and having the trunk close and then re-open when you press the close button. The trunk latch was known to be defective and has been re-designed. This same part is used on the A4,A5,A6, Jetta and Passat.</p>
