Mercedes-Benz S500 instrument cluster issue due to damaged MOSFETs on Mercedes-Benz S500

Some Mercedes-Benz S500 owners report experiencing instrument cluster issues attributed to damaged MOSFETs, particularly the BUZ102 power transistor chip. This common problem can result in partial or complete malfunction of the cluster, impacting the display and functionality of essential gauges and indicators. While repairing the instrument cluster can be a cost-effective solution, as replacing the damaged MOSFETs is significantly cheaper than purchasing a new cluster, owners should be aware that Mercedes-Benz replacement parts can be expensive. Fortunately, alternative repair services are available that can diagnose and resolve these cluster issues, potentially offering cost savings. Understanding the critical role of the instrument cluster in providing vital information such as speed and fuel level is essential for vehicle operation.
