W208 Clk Boot Lid Lock Issue

[Pjones1001]

I have a 2001 CLK430 cabriolet, and I have a problem with the boot lid, which isn't quite the same as all the other boot lid problems.

Alarm was going off randomly, so I removed fuse 20(?) from the fuses in the boot to try to disable the alarm. Boot is now locked... I can't open it on the key fob, or from the switch on the centre console (because I stupidly took out the fuse) and, naturally, the lock cylinder is seized. The battery is fine.

So I've drilled a 10mm hole in the boot lid, and I can get a hook in there to release the book lock, and the lid pops up about 5mm. The light on the switch on the console comes on to tell me the boot's open. However, my car has option 884 "Additional boot lid lock", and I suspect that's still locked, because I still can't open the boot.

I can find almost nothing about the additional boot lid lock on the internet, but I'm assuming it's electrically actuated, so I'm hoping that pulling one or all of underbonnet fuses 8, 9 and 17 will cause that additonal lock to open.

Can anyone here provide any real-world experience or expertise as to how I might get the trunk open? I feel that even making big holes in the bodywork won't help as long as that additional lock is still locked.

Many thanks.

Yes, I've looked everywhere for information. This issue isn't covered.

My car is a convertible. There's no way into the boot from the rear seats. I can already release the cable, that's not the problem.

Got you sorrio. Suggest you find parts schematic showing locations in boot, go from there.

I've got one of those too. My issue is being unable to release the additional lock. I know where it is, but it's locked

Is it key, cable, or electrically operated?

As per my original post, I don't know. That's what this thread is about.

I guess that's why I suggested schematic of pts, if lock electric guess u will see wires? If mechanical, no wires or plug?, if cable, likely pt nu for cable?

The diagram I have only shows the position of the hardware. As I said in my OP, I expect the additional lock is electrical, and I'm asking if anyone knows which fuse or relay might energise it.

From memory some fuses are in boot, which won't help u much. And I guess you hav already checked the handbook.. Prob looking to call dealer of nearest indie for that info. Good luck
