A few weeks ago, the boot catch on my SLK 350 came loose, and caused some damage to the boot latch. I've secured the latch, and bought a replacement latch on eBay, but now there is a further problem - the boot lid is now completely jammed.

At first, I could hear the latch trying to work, but even that has stopped now. I can turn the physical key, and feel some resistance in the latch handle, but it doesn't open the boot. My local dealership wants £200 just to look at it, with no guarantee that it can be fixed. I've spoken to a couple of specialists locally, but they are bereft of ideas.

A further problem is that now the roof won't activate (luckily it is up!) The boot separator is open, and the "Close Boot Lid" warning light comes on, even though the boot is stuck shut.

Anyone got any bright ideas, please? Have you heard of this before? Is there a magic fix? Or should I buy a replacement boot lid off eBay too and set about it with an angle grinder?

No on the angle grinder. When you start on this, you should have somewhere dry to park the car, and should prepare to not drive the car for a few days while working on it.

The external handle is an electrical switch, not a mechanical switch - the "feel" of the handle has no relevance.

If I were you I would start by relieving the pressure in the vario roof pump and raising the boot lid manually - to see if you can see what is causing the problem. It may be possible to open the latch manually (I have never tried this).

There is a switch inside the latch, and there are wires for this switch that traverse the hinge, you will want to check these.

I take it the relief valve is with the pump?

Depending on that, OP may find these useful.

Note that separator triggers a switch. If open you cannot move the roof.
If sensors detect boot will not open then roof will not operate to prevent damage.

I'm going to eat my words here:

In fact, the handle is both a mechanical and an electrical switch, and I have no idea how it works.

When my battery is connected to the car, the handle acts as an electrical switch, no resistance is felt other than the electrical portion. But when the battery is disconnected it turns into a mechanical switch.
