Question Answered: 

I would suggest you just go to an auto radio shop and have them remove it for you, they will probably do it for free. Not using the proper tool can be done, but it can easily scar up the face of the unit.

Sounds like you need to take it back to the place that did the work. It sounds as though the valve timing maybe improperly set.

Usually vehicles that have a flashing anti-theft light on do not start. I am going on the assumption that you have Pats system, where the keys have a chip in the plastic part of the key. The Pats system lets you put the key in and turn it, the chip is recognized and the vehicle is allowed to start. When the chip is not recognized the anti-theft light flashes and the motor may not crank over or the it will crank but not start. It will take some diagnostic know how to go through the steps to find your problem. Without more information and certain tests and their results it will be difficult to tell you if it is major or not. At this point I suspect you have tried to jump start it or charged the battery and tried it, did it start? If it did, did the battery die again? if you charge the battery, then leave it disconnected from the vehicle, will it stay charged,(hooking it back up a few hours later , it cranks or starts). Knowing this will tell us if the battery is bad or the vehicle is causing it to go dead. Are the battery terminals dirty? There are some thick wires coming off of the negative battery cable, are they corroded? Is there signs of the wiring insulation swelling from corrosion?These answers will help us help you.

Normal programming of the radio security code follows these steps. 1) turn key on 2) turn radio on 3) word code should be displayed 4) enter 5 digit radio code and enter, radio should operate. If you have tried this three times consecutively without success, wait may be displayed, you will have to leave the key on for a period of time until "code" is displayed again. You may need to connect a battery charger, because it may take an hour to do so. If this fails again, you may have the wrong code and you will have to get the proper code from your MB dealer, (they will need to remove the radio and get the serial number from the radio chassis). If you have had radio repairs before they may have not updated the radio code.

Hate to tell you this, but CD changers do have their share of problems. Usually if you can eject the magazine from the changer then reinstall it, you should be able to hear the CD changer load the CD's. If the changer does not go through this process it usually is replace first. You can remove the changer and inspect the connectors to make sure they are seated properly, but if connectors are okay, the changer should be replaced.

I have to ask one question and when you answer it, you may have it figured out. Does only one actuator go up and down very fast,(machine gun effect) or do all of them? If only on is doing that, then it is most likely the bad actuator. Usually the driver's door latch is the culprit since it is used the most. The actuator is part of the latch, so the latch will need replacing.

First, car does not start, does the starter crank the motor over? Easiest thing to try is another ignition key,(known good key). The key you have maybe defective or erratic and this will cause this behavior. The ignition keys hold certain coding info and if all the info is not transmitted to the vehicle you can have the symptoms listed. If you do not have another key you may need to order one from MB by the VIN number. The keys are over $200, so at this point you may want to pay to have a quick test of the vehicle by a technician/shop, it may reveal obvious items that may need addressing that the display did not show. Sometimes this is the best money spent instead just throwing parts at it.

From the info supplied, I have to assume that the front brakes have been inspected and they are found to be ok. Make sure that the wires for the brake pad sensors have not come in contact with the wheels, if these wires wear through it will cause this.Make sure old sensors have not been reused.You next will have to inspect the wiring for the warning system. You must look for wires that a not in their holders and have chafed on other moving parts.

The switch for the alarm is attached to the key cylinder of both front doors, so the driver's door trim panel will need to be removed to inspect the condition of this switch. It may be broken or disconnected from the key cylinder

Question Answered: 

I would check the speed sensor. It should be at the rear housing of the transmission and have two small gauge electrical wires plugged into it. It may or may not have a large cable coming out of the center of the sensor, if it does it is a mechanical drive for the speedometer. If it has the large cable, you may have a speedometer drive gear stripped. If there is a lone sensor with the wires plugged into it, this sensor maybe bad. If you have access to a multimeter check the resistance of the sensor it should be below 2K ohms. If the sensor passes this test you will need to perform further circuit tests, a wiring diagram is highly recommended, not having it can waste lots of time.
