Need help with diagnoses (alarm?)

[racerx12367]

2003 230slk My daughters car. I live in NH, she's in the Orlando area. The car won't start. The car was rear-ended about a year and half ago requiring work to alighn the trunk lid. This wasn't don correctly at the body shop and was then sent to a Mercedes dealership to correct the problem. After a few months the car wouldn't start, back to Mercedes. There the PSE was replaced at a price that they could afford. This problem has once again reemerged. Now they are telling me that the tumbler assembly needs to be replaced in the ignition. I have no idea if the trunk is leaking at this time, my daughter says it isn't wet inside the trunk. I haven't been able to inspect the wires to the PSE....What do you think? They want $1100 to do the ignition. I'm sure that it can be done cheaper, but does it need to be done at all? I've enclosed the test results from the "brain". Thanks for your help
