2003 Jetta TDI Automatic -- the trunk lid takes two hands to raise and a heavy hand to close. WD-40 does nothing. Dealer says I need to replace the entire mechanism for approximately $400. Any other solutions?

Re: trunk lid is very stiff to open/close
The hinges for the trunk will need replacing. not the shocks. about $60 a piece from VW. do it yourself about 4 bolts. just get someone to hold the trunk for you. its not necessary to paint the new hinges

if you have a chance to put the car in a heated garage somewhere for some hours it would help...
-after the car is warmed up you need to spray some silicone spray on the trunk door and around all the rubber sealing and the fuel door hinge to have it better prepared for freezing temperatures.... blog carlist my
check the trunk latch on the lid,use a screwdiver to see if it locks when you insert the shaft of the screwdriver in the latch. if it doesn't lock check the inside trunk release could be stuck in the up position.or the latch is dry try to oil it with dry lube or wd 40
#1 The latch isn't lining up with the lock. Look closly at the lock assembly as it comes down on the latch the insure that enverything is going where it fits. If not use a screwdriver to pry, or soft blows with a mallet to move the latch.
#2 The lock isn't open. Look inside the lock as you use the key to open the trunk. Now with the key turned as you would to open the trunk, make sure the latching mechanism of the lock is open to allow the latch to slide into place. Use a screw driver to open it if it is stuck. A little WD-40 will cure it is this is the problem.
Stick little red nozzle of WD-40 or similar, in key hole as far as you can & give it a good spray & give it a little time, then spray again. Keep trying lock occasionally & try your key as well. When/if you get lid up, give it a good spray from behind as well.
There may be something obstructing the path. Possibly the wind deflector? It's also possible that the sunroof knob is out of sync with the sunroof itself. Try putting your key in the drivers door lock, turning and holding that position while the sunroof closes. (not sure which way you have to turn) You can also close it manually with a hand crank (which is actually an allen wrench)
most likely cause is latch cover plastic has broken and got lodged in the latch mechanism. now the fun part, fold down back seat , slide into trunk with a phillips screwdriver a flashlight and a large strait blade screwdriver, once in trunk remove trunk cover, then with strait blade unlatch the trunk. once lid is open remove latch and take out broken plastic to free up latch and reinstall then retest before closing trunk.
You can open it old school. Insert the key in the trunk lock in the VW emblem and turn it while pushing down on the trunk lid with the other hand a little bit. It should open. The plastic arm that the motor is pushing to unlock may be broken. I have the same problem. You can see it if you unscrew the fabric from the trunk lid and press the button on the remote. There are about a dozen fuzzy head screws (nicely masked btw.) that hold it. I am still looking for the proper name of the part so I can order it for my car.
If your lock actuator engages (you can hear the sound it makes) with the remote/electric button on the door, but the trunk doesn't open then the problem is likely a broken plastic arm that the electric assembly pushes. You can see it if you unscrew the inside cover from the trunk lid and try the remote. I started having the same issue with VW Jetta 2002 GLS that was rear-ended 8 months ago. My guess is the cracked plastic finally gave out in the cold weather.
