2003 CL55 amg trunk issuie please help

Hi I have a beautiful 2003 CL 55 amg in near perfect condition I have own this car for 5 years and had very little issues with it. Recently the trunk does not open electronically. Only if the battery is disconnected it will open for a little bit then completely stops it also has completely stoped closeing electronically I was told I need to replace the trunk computer modeul but it’s $1000.00 part new is there a cheaper way to fix this issue?

Is it the latch or the actual hydraulic opener? There are Youtube videos showing how to fix both of these issues using the S class but they work the same way. The hydraulic opener will leak and stop working. The latch actuator tends to break causing air to leak and the trunk will not unlock unless you use the key. very easy fixes.

Well the actuator is in perfect condition when I removed it I didn’t see any cracks at all anywhere. Also my trunk lights don’t work any idea on the issue could be? Only if I disconnect the battery and reconntect the battery will the trunk only open electronically but still does not close . If the issue is not the actuator is there anything else it could be? Maybe a fuse???

Sorry Amgfan80, i wish i had seen this earlier. I had the same harness issue on my 05 CL55. My mechanic said that with the constant opening and closing of the trunk and the harness and wiring always moving over time the wires break. But not that expensive of a problem to fix as you probably found out. The other area that is a similar problem is the retractable exterior mirrors. I opened and closed mine daily while parking (had it set to automatically do that) and over time the wiring to those broke as well. But again not an expensive problem
