Mt car is a 320d E90. I get an intermittent engine fault running on reduced power message. Took it to get diagnosed and the fault code DTC 4755 showed up mentioning boost pressure actuator. Position control. The mechanic mentioned that the drainage system was blocked and there was moisture in the ECU. Dried it out but the problem persists. Any advice please. Location New Delhi India.
