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.
