These instructions pertain only to the multi pin plug switch on the back of the ignition lock and key assembly. THEY DO NOT cover the key tumbler or steering lock removal. A bad switch can exhibit the following symptoms: Intermittent starter motor contact (first check your starter motor and neutral safety switch at the transmission before replacing this switch) and/or intermittent operation of high amperage electrical components such as your heater blower motor,etc (first check heater motor operation and fuses before assuming it is your switch).

The primary electrical ignition switch on these Mercedes is located on the back side of the ignition key and steering lock assembly. Access is through the instrument cluster hole in the dash board. If you are not familiar with removal of your cluster please order my Instrument Cluster Removal and Component Replacement Guide available separately. No instructions for removal of the cluster are included in this kit. On most models you will need the special dash pull tools to remove your instrument cluster. Please see related products below:

NOTE TO DIESEL OWNERS: It is very common to see black oil in and around this switch. This occurs when you have a leaking shut-off valve and engine oil is sucked up into the ignition switch. If you see this on your car I recommend you replace the switch BEFORE it fails on you. Since it is such an inexpensive part it is worth the preventative measures to replace it.

WARNING: If your key is sticking or getting increasingly more difficult to turn, this is not usually due to failure of the electrical switch. It is more likely you have a worn key tumbler assembly and / or steering lock pin. To learn more about this problem type "ignition lock" in the search box. 

IMPORTANT: Getting this switch in and out is difficult without removing the entire lock assembly. This is a challenge but can be done with the special tool supplied in our complete D.I.Y kit. See related products below. Can you make this special tool yourself, but it is not needed if you remove the steering lock from under the dash.
