Is the Mercedes CLA equipped with a timing belt or a timing chain?

The Mercedes CLA is equipped with a timing chain, which is located within the engine and is lubricated by engine oil. Unlike timing belts, which are external to the engine and can dry out and crack over time, timing chains tend to last longer. To prevent timing chain issues, it is important to regularly maintain your engine, change the engine oil at recommended intervals, and use high-quality engine oils and oil filters. Ensuring the proper oil level will help keep the timing chain well-lubricated, especially since many modern engines tend to consume oil. Timing chains are designed to last the lifetime of the engine, but with high mileage, around 200,000 miles or more, there may be a need to replace the timing chain due to potential timing issues.
