The roof operation is fairly complicated, consisting of a lot of electricals (e.g. controller, hydraulic pump motor, relays, fuses, position switches), 7 hydraulic cylinders and related systems operating properly (e.g. windows lowering, rear head rest roll bar).
There is a ton of information within this forum regarding the diagnosis and repair each of the above.
Have never heard of a dead battery replacement causing a roof mechanism failure.
However, windows must fully lower for the roof mechanism to work.
Was the required window reset done after the battery replacement?
After replacing a battery, there are 3 required resets (e.g. radio code, turning the steering wheel lock to lock in both directions, fully lowering and raising the windows while holding a short time in each position).
If the window controller was reset now working properly, check for an electrical issue that is keeping the hydraulic pump from working (e.g. relay, fuse).

Hi thanks for the reply the windows have been reset and the steering also thr rear roll bar goes up and down but roof still won't work you can hear the motor weering but it just won't release. Spoke to mercedes and they are saying that it needs to be reprogrammed at £175 (about 5mins work) I believe there is a simpler option as I cant be the only person this has happened to! Any more help would be very much welcomed

The STAR diagnostic / programming software would be needed to do this.
While I understand that it can provide some limited roof diagnostic information, not really sure if reprogramming this system is required and/or valid.
If it is, many independent mechanics have the STAR software and typically would charge less.
While the following would not have anything to do with the battery replacement, from your last note and the age of the car, you could have a leaking hydraulic cylinder.
If this is the case, you can check the pump's hydraulic fluid level, which is easy to do through an inspection port in the trunk (see page 4 at the following link).

Hi mate read your reply over and over again last night so are all these latches and locks controlled by hydraulics? And is it just a normal code read that gives you all your fault codes or is it another plug in point a the back for the roof cheers

Another common issue has been a relay. Fortunately, the same relay is used elsewhere (believe it's the fuel pump relay) which can be swapped to check (you'll find more information on this via searching the forum).
Another easy check would be the luggage cover. The roof can will not operate if it's not in place correctly (e.g. up). Make sure the position inter-lock switches are being actuated (weren't knocked askew while the battery was changed). The rollers must located within their tracks correctly, in order to close the switches properly.

Lastly, North American cars have 2 ports for reading codes. The OBCII port is under the drivers side dash and only deals with emissions. The STAR port in located in the rear of engine compartment (passenger side) and has many more capabilities (e.g. for diagnostics, resets).

From the photo, I could not identify the switch you're referring to.
The document below will show you more more information regarding the roof's switches, functions and locations.

Does S84/5 (soft compartment cover open switch) exist on a MY2000 W208 CLK430?, If it does, where is it? The WIS picture is zoomed in too far to really see where that switch might be.

A picture and location of the switch is shown on page 7 in the WIS document in post #10 above.
You'll have to remove some of the compartment cover carpeting in that area to see it.
If your having an issue with the operation of your roof and suspect that the switch is not working properly, I can tell you how to verify that it's functioning properly.

CLK 430 W208 MY2000
All CLK A208s cabriolets, produced between 1998 and 2003, use the S84/5 compartment cover open switch. A picture and location of the switch is shown on page 7 in the WIS document in post #10 above. You'll have to remove some of the compartment cover carpeting in that area to see it.
Thanks. I will be checking the electrical operation of all the switches related to the top system via the N52 connector so hopefully that will give me a better clue as to which might not be working properly.
