Hey guys,

Last weekend I installed the Naviks video input harness. I disconnected the battery, installed the harness and then reconnected the battery. When I fired up the car i noticed my CEL was on. I ran a quick scan and it came back with fault code P0156 O2 Sensor Circuit Malfunction (Bank 2 Sensor 2).

Since the O2 sensor is a electronic part I'm thinking the disconnection of the battery has something to do with the fault code.

Something else to note I'm hearing a whooshing noise at WOT coming from the mid pipes. It definitely sounds as if theres a valve opening somewhere on the exhaust line when the car is on full boost, which doesn't make sense but the sound is loud and only occurs when the car is on full boost. Not sure if this is relevant or normal for the X5M but I'm going to look into this further on Saturday morning.

Anyone else experience these issues and if so how did you remedy?
