Before you begin, open the hood of your Mercedes A-Class. Start by removing the exhaust manifold by loosening and taking out the mounting bolts.

Next, detach and remove the manifold itself, then disconnect the hoses connected to the glow plugs. At this point, disconnect the positive electrical connector.

Once you complete this step, you can unscrew and remove the glow plugs, finishing the disassembly. To install the new glow plugs on your Mercedes A-Class, follow this procedure in reverse, and you will have completed the replacement.
