What are the steps for removing and installing the ignition switch of a Mercedes-Benz C200?

There is a bright ring at the position where the key is inserted. Insert two small tools into this bright ring and turn it counterclockwise. After removing it, the ignition lock can be pushed backward and taken out from the position above the brake pedal. Then, disconnect the plug on the lock to remove it completely. Below are the specific details of the Mercedes-Benz C200: 1. Dimensions: The body dimensions are 4784 mm in length, 1810 mm in width, and 1457 mm in height, with a wheelbase of 2920 mm and a fuel tank capacity of 66 liters. 2. Powertrain: The Mercedes-Benz C200 is equipped with a 1.5T turbocharged engine, delivering a maximum power of 115 kW and a maximum torque of 250 Nm, paired with a 9-speed automatic manual transmission. 3. Suspension: It features a multi-link independent suspension system for both front and rear.
When removing and installing the ignition switch on a Mercedes-Benz C200, special attention must be paid to safety. The first step is to disconnect the negative battery cable, loosen the nut with a wrench, and insulate the terminal to prevent short circuits. Then remove the lower steering wheel trim panel by unscrewing the fastening screws with a T20 screwdriver, gently prying off the plastic cover to expose the steering column. There is a locking pin on the ignition switch housing that requires a specialized tool to depress before the switch core can be extracted. When installing the new switch, align it properly and push firmly until it clicks into place, then reassemble the trim panel without overtightening the screws. Finally, reconnect the battery and test the ignition function to ensure smooth rotation. The entire process may take 30 minutes to an hour, allowing you to save hundreds in labor costs by doing it yourself, but remember to wear gloves to prevent cuts. If the airbag warning light illuminates, recheck the airbag wiring harness—Mercedes parts are precision-engineered, so avoid forcing components to prevent damage to surrounding electronic modules.
I've done quite a few car modifications, and replacing the ignition switch is pretty straightforward. First, disconnect both the positive and negative terminals of the front battery, wait a few minutes for the capacitors to discharge before working safely. Adjust the steering wheel to its lowest position in the driver's seat for easier access, remove the bottom trim panel to reveal the switch assembly, and use a Phillips screwdriver to loosen the retaining clips to remove the lock cylinder. When inserting the new part, don't push too hard; test the rotation flexibility before reassembling the trim panel and tightening the screws. The crucial step is the electrical test—start the vehicle and check that no warning lights appear on the dashboard, then you're good to go. All you need are a few screwdrivers; no professional equipment is required. You can finish it on a weekend afternoon and learn more about car structures in the process. Regular maintenance with some lubrication can extend the switch's lifespan.
