Default rear trunk latch wont latch

so...

a couple weeks ago, i opened the trunk with the key fob, and it won't latch. luckily, it stays closed by itself, and looks latched...but...it'd be really nice to have a working trunk again.

anyone have any suggestions for this one?

thanks,

i had this issue on my '05 golf. the sensor in the trunk latch was faulty. it would mechanically latch but the sensor would not trigger the lock. i had it replaced under warranty.

Same issue in my 02 golf. Replaced under warranty but took over a week to get the part from Germany.

Default Spring

There is an internal or should I say "infernal "spring in the latch assy that can be knocked off by the plastic cover that envelopes that assy. I had to remove the plastic that had broken off and reinstalled the spring with a set of angled needlenose....delicate operation but saved a bunch of money and time.

Mine failed because of a leaking wiper/washer motor that corroded the connections. Common on Golfs and Wagons.

My latch also does not latch anymore. I can close the trunk, but it gives me a 'door ajar' light on the dash and the horn does not sound when I lock with the keyless entry fob.

It did this on occasion before when it was very cold, but now its stopped completely.

If I open the hatch, I can rotate the 'locking hook' on the hatch release with my fingers until it is in the 'closed' position and the alarm then 'locks' and the horn beeps its 'locked' signal. ...but the trunk locking hook does not stay in the closed position. It returns to the open position.

The Hella brand trunk release motor seems to be working fine, and its still attached to the trunk lid, its arms appear to be moving the pieces they are attached to.

I have read about the 'spring fix' where you either repair the broken spring or replace it with something else like a rubber band. I keep a fair amount of tools in my car and I would hate for someone to take them so I need to fix this correctly.

Any suggestions?

Fixed!

I removed the trunk latch using my 12 point torx bits and removed the plastic cover. After cleaning all the junk outta it with some PB Blaster, I put dielectric grease in the 3 pin sensor and a bunch of white litheim (sp?) grease in the lock mechanism.

Im guessing that the latch couldnt rotate enough to lock properly.

Most likely it will be the srping inside. Remove the latch from the car and look inside the mechanism. There are pics around here somewhere to show what it looks like but when its in your hands, the problem is really apparent.

Smile Trunk latch spring fix.

Just wanted to thank weasel for the trunk latch tip. My 2001.5 Passat (non-diesel.... not available back then, waiting for common rail technology now), trunk latch failed but I was able to:
  1. remove the upholstery from the inside of the trunk (by carefully prying around the edges),
  2. remove the latch from the trunk lid using a 10mm socket wrench on the two nuts. Had to pry a little at the trunk metal to get the socket in here.
  3. removed the black plastic surround on the latch that peels back and unfolds around the latch,
  4. and finally see aforementioned weasel's spring languishing.
  5. I then used a darning needle to hook the spring back on to the latch.
  6. reassemble, check, hey presto. I've been saved a bunch of hassle and cash.
Thanks again!

That's how I fixed mine.
The most time consuming part is removing and installing the upholstery.

Same problem on 2003 Jetta GL sedan. Same fix except for:
  1. remove the upholstery from the inside of the trunk (by removing the phillips-head screws),
  2. <same>
  3. <same>, then remove the white insert with the two studs on it to which the black plastic was attached (to do this, you may have to detach the electical cable, the wire cable, and the metal rod with the black plastic fitting)
  4. <all the rest is the same, but I used a wooden barbecue skewer instead of the darning needle>
Whole thing took 30 minutes, including several trips back in the house for tools I should have thought to bring.

Many thanks, all, for saving me lotsa $$$!!!
