Trunk lid pops open when Locking the Vehicle. Have to close it everytime i lock. This happened after an accident and replacing entire trunk lid.

Close the trunk.... Just kidding

this might sound odd but it sound like the sensor that sees the trunk as closed is either mis adjusted or faulty.

spray a squirt of penetrating oil like wd40 into the receiver that secures the trunk lid. For example the lid should have a loop or square of metal that when the trunk lid is closed joins with the locking mechanism.

Shoot a a squirt of we 40 into the locking mechanism and see if the light goes out.

Do you hear a click noise at all? You could try this.. One person sit on the truck lid, (heavier may be better) relieving the lift tension on the lock, while the other person push the button and hold. Sitter then hops off and pulls up on the trunk lid. If not working, Sitter person could try gently bouncing on the trunk lid while you hold the button.
Groceries still in trunk after 3 months???
If no joy, then you need someone to replace or remove the lock and pop it with a screwdriver.

This could be shorted truck lock switch issue.

have a look at the trunk latch mechanism.sometimes they get closed when they should be open(the fingers that lock the trunk lid closed).if its in the closed position just unlock the trunk with the key and use something to pop open the lock(fingers) then the trunk will close again.

It is right on the locking mechanism. When you pull the trink release, it retrieves and the trunk pops up. It is on your trunk lid, right in the middle. There is a small metal plate that you can be pushed bak if it is locked. When you use the trunk button, that metal piece releases and the trunk opens.

The locking mechanism either needs replacing or cleaning and lubricating but more often than not it's likely the striker pin needs readjusting to bring the lid fully shut.

the only way i have ever been able to open trunk is to remove lic plate and drill a hole threw deck lid to access release to trunk. be very careful if you attempt this.

I had exact same problem, but what I found out was a three step solution to the problem.
1) The trunk lock above the trunk lid tself - sometimes looses coiling retention for the lock to work properly, which in effect does not properly lock wrap around the pull down electronic unit located in the body of the car/trunk that catches and pull the trunk lid down SOLUTION: check and make sure lock is works properly. you cab check by opening trunk and locking it with remote key, then pry the lock with a screw driver to see if it unlocks or stays locked

2) The motor catching unit in the body of the car/trunk that catches the lid and draws it down can be off balance (sitting too low to catch the lock (upper trunk lid with lock) to pull it down and stay locked. Have a mechanic - Audi preferrably, check the positon and allignment to adjust it, so it can catch trunk lid and lock to stay locked. HOPE THIS HELPS!

spray the lock with penetrating oil like WD40 force open remove lock mechanism spray lots of oil force back and forth I used hammer with flat piece of wood in front (metal to metal) you will destroy it once trunk open remove if necessary lubricate until goes in and out freely
