Trunk wouldn't open without key (fixed)
I had this problem yesterday in my 2003 CL500. Suddenly the trunk door stoped responding to remote and door key and did not opened. I opened it with emergency key and closing function was normal. Everytime i pushed the button i heard a fissing sound. Some like air leak. It was from unlock acuator. Very common in w220 and c215 ( w215 ). So the Mercedes Service told me to change the complete trunk central key part a2207500684 (very expensive one). But i did a research and find out that little acuator exist in market with part number a2208000275. This part isn't listed in official Mercedes spare part selling system. I tried to buy it from ebay but since paypal currently doesn't work in turkey i didn't succeed. So i thought about a resolution and did a great job. Only 3 plastic zipper and that stupid part is now resistant to even a nuclear blast 😂😂. It worked even better than new. No need to glue it.
