BMW X4 2016 B47D20A 150000 miles
Hi everyone, after running a diagnose on my BMW F26 B47D20A 2016, i found a faul related to AUC sensor C90D60-sensor internal fault error. As the original one PN 64116826347 is out of order, advised by the spare parts seller , I ordered 64115B3A890 (hope they are compatilbe). After installing the new sensor I got another (different) error , C90D74-Missing LIN slave.As I found, LIN is +12V and is connected through fuse F44. There is any connector between F44 and the sensor plug?
And if the answer is yes , can someone advice where is locaded that connector? There is no any other fault present on my car. Thanks and best regards,
Emilian

I measured presence of +12 on sensor connector pin no.1, ground on pin no2 and on pin no.3 + 8.5 V. Apparently all ok. I put back the old sensor, I got the same error-Internak sensor error.
