Re: [bmw] OBD-II codes 1523, 1478

[Matt Brannock <matt0611@xxxxxxxxxxxxxxx>]

I went to this website: http://www.actron.com/code_lookup/index.php

These are its definitions for those codes:
1523: *Engine Oil Pressure Sensor/Switch High Voltage
*1478: *Exhaust Pressure Control Valve Circuit High Input
*
Hope this helps
