Hello everyone, and greetings from the newest member of Bmw family with a 535d production 2012/06. Yesterday i was doing a diagnosis at a local service shop, and the only thing that came up was these (picture attached). The technician explained to me what was wrong in technical manner which i don't fully remember, something of voltage being transmitted from this sensor was around 398(cant remember the measurement unit sorry haha) while 400-600 was optimal. Now i am having some trouble to find the part number online and I've looked up a decent time. If anyone can help me i would be very grateful. I have attached the picture i took at these parts from the engine schema.

Cheers
