How to Replace the Spark Plugs in a Mercedes A-Class

Model: Mercedes Classe A W176 - Years 2012-2018
Part: Spark plugs

To replace the spark plugs in a Mercedes A-Class, open the hood to access the components inside the engine bay. You will need to remove the plastic cover on top of the engine block to access the underlying components. Next, loosen the bolts securing the air intake tube to gain access to the top of the engine. This will allow you to disconnect all connectors attached to the coils. Once the coils are removed, you can pull out and replace the underlying spark plugs.
