What's wrong with it? Is it the plastic arm in the middle that's broken? If so, just remove all remnants of it - it's not needed for the operation of the cover. That plastic arm is only used to lock the cover open while repairing the hydraulics.

Part number is A2097500521. USA pricing is over $300 retail, $230 discounted. I can't help with pricing/sellers in your country (I know you aren't in the USA because the CLK280 was not sold here). Consider updating your forum user's profile with your location so others may be able to help.
