Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, if the ML starts and dies it can be caused by a faulty key. If you have a spare key I would try that first. Next you can try turning the key on without starting the car and leave it on for 3 minutes then start the car and see if it will idle. As far as missing fuses, I would just install a 10 amp fuse in any empty slots in the fuse box and see if that solves the problem.
Let me know if you have any questions.
If only 2 doors are not working the problem is most likely to be the door lock actuators.
