Mercades 430 wont start back when hot for 15
If it is a gasoline engine- check on replacing the thermostat. If it is faulty it will not let your car run warm, making it think it is way to hot too be in operation. part is relatively cheap as well, and labor not too far from that unless you are comfortable under the hood (medium DIY project)
Glow plugs won't work when
Check voltage and make sure that the glow plugs when cold are getting the right amount of voltage, if they are replace the glow plugs
Xenon problem wont stay on
The ballasts take the 12v power of the car and amplify it to 22,000 volts to ignite the lights. After that, they run at a constant 85-95 volts to keep the lights on. You may have a weakness in the electrical system that is causing the battery voltage to drop just enough during startup that the lights won't ignite. Are you turning them on before cranking the engine? You shouldn't do that for a few reasons (if you are) - one, the life of the xenon ballasts can be severely shortened by flickering, and two, having the lights on puts additional strain on the battery while starting, as most of its amperage is needed to turn the engine over. Get a piece of 10 gauge wire (a stereo shop can sell it to you) a couple feet long. Put a ring terminal on each end and attach one to the battery's negative side, and the other to a bolt in the engine bay. This will give your car an additional ground point that can help its conductivity better and it may help to alleviate your problem.
If the problem is simply that the lights will not turn on, you may need either new bulbs or new ballasts. They're very expensive from a Mercedes dealership (on my Audi, the bulbs are over $200 each and the ballasts are even more) but you can find them online for a fraction of that.
Mercedes bonnet thinks its open.

You normally can't disable alarms as there is a computer in-between the switch and the light on the dash. You have to fix the fault, not find a way around the problem.
The easy way is to connect a professional grade scan tool computer, check for codes and read the data that is registering the problem.
