You may have a fault in the wiring for that sensor that is intermittent causing the code. The module that controls the system in E39s is notorious for failure. I'm about to purchase my third.
Module Masters can usually repair them for $300, otherwise prepare for a chill at the dealer.
No, my husband had to talked to someone at a garage that told him to change the sensor

We did go to (non BMW place) Auto place to get codes read last night and it came back as PO153 and PO430

Thanks for your reply
