2001 CLK Cab w208 Rear Bow Lock Replacement

[Pblewett]

Hi there,

Can anyone help?

My 2001 W208 CLK 320 convertible roof stopped opening back in July and I have been fault finding since. One fault that seems to have developed (and it could have been since I have been opening/closing the roof manually) is that the rear bow lock mechanism which is normally operated hydraulically but manually just now by an Allen key will not lock without being given a “kickstart” with a screwdriver pushing against the latch mechanism. It simply will not turn with the Allen key, although it will unlock all the way with the key.

I have removed the cylinder and lock (P/N 1247700426) and can see no obvious damage or reason why it would bind in this way.

Has anyone seen this before, and if so, what is the solution?

I’m now in the situation where I cannot lock the rear bow and use the car in the rain! I’m getting desperate!

Thanks for your thoughts and advice.

Cheers

You usually need to push the roof down into the lock a bit to get it to grab. I think there must be a part that needs the loop of the roof to touch in before it will operate. Prevents the hydraulic part missing the loop when operating automatically
