I have a 2003 Boxster

First of all, I "searched" the forum for answers, but could not find any solutions.

My rear trunk has always been tempermental and recently refuses to open. Pressing the remote key (or the interior switch) will cause the actuator to pull the cable (I can hear it whirring away) but the trunk lid refuses to open. I can open the trunk using the manual emergency release and I have oiled / cleaned all of the mechanical linkages and springs, but still no improvement.

I took a careful look at the cable linkage and the cable appears to have about 1/4" to 1/2" of slack. It is possible that the actuator just can't pull the cable far enough to release the trunk ? Is this a normal condition ? Can the cable be adjusted to remove the slack ? If so, any procedures out there ???

Many, many thanks in advance

It shouldn't be too hard. My cable broke and it's on my project list..

However when I was washing rear trunk carpet I saw the adjustment point.

You have to remove the black plastic that sits over rear trunk latch (4 or 5 screws) and you will see where the cable is hooked up

Loosen the retaining screw (I'm not sure if you have to take out the metal plate on top of it or not) and tighen the cable.

Now this is what it looked like when I inspected it.. I didn't do it myself.. so "results may vary", maybe someone with more technical knowledge can give exact instructions

OK, I had some spare time and decided to dig around in the rear trunk.

The solution is stupidly simple. The cable actuator is mounted in the trunk area by wrapping it in a sticky foam blanket which is then shoved it position. The device is held in position by friction and not a mechanical fastener (which would restrict the actuator's tendency to be pulled toward the cable attachment point). I was able to reach in and pull the actuator to the left and slightly adjust the sticky foam blanket....the cable slack is now gone and problem solved.

I must say that this is a really cheesy design by Porsche engineers.....apparently whoever came up with this solution was at the local hofbrau haus when Newton's 3rd law of motion was reviewed in Physics 101.
