Good morning,
I understand there are other threads on this issue, but I wanted to the additional factors in my case

2011 bmw 328i e90 N51

My TPMS system goes inactive after about 30-45 minites of highway driving. When I come to a stop and reset the reading, the TPMS system then becomes active again. This has been happening for a few months.
Just last week, my oil level measurement is also inactive. I have read many threads, I have seen many times people replacing the oil level sensor and not fixing the issue. I am skeptical this may be the IBS sensor as well.
I feel a little uneasy driving unable to read oil, as I know I had a slight valve cover leak which I am also planning to fix

Any help is appreciated. Thanks!
