Starter motor on this car is imposible to get to..better find the post forward of the drivers side fuse box in the engine compartment where a bunch of wires come together. This is a positive terminal attach red jumper here put the negative jumper on any bare metal bracket of the engine

There should be a positive charging post under the hood. Hook up jumper cables to this post for positive and the engine for ground. Then get in the car and pop the trunk with the trunk release button.

I have the same intermittent problem on my C230 in that the trunk lid switch will not open the trunk lid from inside. If you pull it the least bit hard, the little plastic switch button breaks off and you have to replace the whole unit. Mine has been replaced twice and five months later it is now happening again. One of the tech's at Mercedes happen to say in passing that the contacts may have a problem in the hot weather and it was acting up during several heat spells. Problem is the assembly is $742.00 installed each time and Mercedes says they only warranty the replacement from the date of the original installation instead of a new warranty on the new part. I am currently fighting Mercedes of America over this as they seem to have a problem with the switch and will not admit it. Everything is so expensive on a Mercedes.
