The BMW Diagnostic Trouble Code (DTC) P1055 corresponds to specific issues with the Valvetronic system.

The BMW Diagnostic Trouble Code (DTC) P1055 corresponds to specific issues with the Valvetronic system. In particular, it relates to the Valvetronic eccentric shaft sensor. Here's what it typically means:

**P1055 - Valvetronic Eccentric Shaft Sensor Plausibility (Bank 2)**

In BMW's Valvetronic system, the eccentric shaft sensor is responsible for measuring the position of the Valvetronic eccentric shaft. This shaft controls the variable valve lift system, which adjusts valve lift to optimize engine performance and efficiency. The sensor monitors the position of the shaft, and if it detects implausible or incorrect values, it triggers this error code.

When you see the P1055 DTC, it's an indication that there may be an issue with the eccentric shaft sensor or its related components on Bank 2 of the engine. The specific cause of the problem could be wiring issues, sensor malfunction, or problems with the Valvetronic system itself.

To diagnose and address this issue, it's recommended to consult a qualified BMW technician or use specialized diagnostic equipment. They can perform further testing, inspect the wiring, and assess the sensor's functionality to pinpoint the exact problem and provide the necessary repairs.************************ **************
