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

Yes

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

Instructions for replacing your upper trunk latch.
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.
Time required less than 1 hour.

Required Tools: Torx 25 driver Phillips screwdriver Small flat blade driver Plastic pry tool/putty knife or other instrument 10mm socket driver (not pictured)
1) Order part number 4F5 827 505 D <a href="http://www.audipartsnationwide.com/partlocator/index.cfm?action=getJointLocator&siteid=215503 &chapter=&sectionids=0,2822&groupid=51 935&subgroupid=3276&make=2&model=A8&am p;year=2005&catalogid=2&displayCatalogid=0 ">Lock</a> from the online or from the dealer. Cost is about $45 online $68 from dealer

2) If you go to the dealer pick up an extra metal clip that is used on the trunk trim that you will be pulling off. They get lost very easily.
3) Pry off cover of emergency release to get to Torx 25 screw on emergency release handle

4) On the other side on the handle pull there is a small plastic door that when opened will reveal two Phillips screws that secure the
other handle lift to trunk.
