Geek2232 Posted October 22 Share Posted October 22 Greetings, I recently purchased a BMW 316d with an N47D20C engine, which was displaying error signals for the O2 sensor. I was unable to locate it, then I realised it was absent. I saw an additional connector that is unoccupied, and I can not see a corresponding wire for connection. I attempted to research this on Google but could not identify its purpose; I am enquiring if anyone might provide guidance. The EGR warning light has illuminated, and I discovered several disconnected vacuum hoses in the engine. I would appreciate assistance with this matter as well, if possible. Postscript: I will include photographs tomorrow. Quote Link to comment Share on other sites More sharing options...

TechWhiz Posted October 22 Share Posted October 22 This connector is intended for engines equipped with a DPF temperature sensor; however, some engines, like yours, do not possess this feature. Typically, 316 and 318d lack them. It will be equipped with an O2 sensor; I have yet to encounter an N47D20C without one. Positioned atop the vehicle's DPF unit, it connects via the auxiliary connector. Which hoover hoses? That age should possess only two vacuum pipes: one connecting the main vacuum pipe to the EGR cooler bypass pressure converter, and the other linking the converter to the bypass. Which EGR code has been generated? Quote Link to comment Share on other sites More sharing options...
Geek2232 Posted October 22 Author Share Posted October 22 Thank you, I will examine it after work. Furthermore, it appears that the O2 sensor was either disconnected or removed from the vehicle by an unknown individual. Thank you once more for your comment.

Geek2232 Posted October 22 Author Share Posted October 22 This is the initial hose located on the left side of the engine compartment; its connection point is uncertain. Quote Link to comment Share on other sites More sharing options...
Geek2232 Posted October 22 Author Share Posted October 22 This hose from the opposite side of the engine bay links to the pipe I am indicating, which appears to have a fitting for it to attach behind; however, there is already a hose from this pipe leading to one of the fittings.

TechWhiz Posted October 22 Share Posted October 22 One side of the oil filter should connect to the main vacuum pipe nipple. Proceed to the pressure converter, located at the position indicated by the red circle in the image. The single turbo side operates at the same pressure as the converter.
