Coils

There are a range of parts that make up the ignition system in your Mercedes. The ignition coils are important parts that are attached to your spark plugs. They generate the current that is necessary to power your spark plugs, which starts the combustion process. It's crucial that they are operating properly so that your engine can run. If they start to fail, a range of things can go wrong. Damaged ignition coils are likely to cause the check engine light to come on after a period of time. Your car might start to hesitate during acceleration. A decrease in fuel economy is also a common symptom due to a lack of spark plug energy caused by worn down coils. This can come as a result of weakened performance. Your car also might start to have a rough engine idle or you could have difficulties starting the engine. Recurring engine misfires are another thing to pay attention to. It's important to replace old ignition coils with OEM parts that will fit your Mercedes properly.
