Mercedes-Benz E220 CDI Models Recalled Due to Boost Pressure Sensor Issue

A potential issue with the boost pressure sensor has been reported in certain Mercedes-Benz E220 CDI models from 2014. The sensor, B5/1, may output incorrect voltage, leading to a mismatch and causing the engine to revert to 'limp home' mode. This can result in reduced performance.

The issue is related to the sensor's ability to provide accurate readings to the engine control unit. Owners of affected vehicles may experience reduced performance or erratic readings. The National Highway Traffic Safety Administration or the manufacturer may have issued a recall notice for the affected models.

Owners are advised to check with the manufacturer or a trusted repair shop for further information and inspection.
