[Solved] P00B4 and 10A001 Fault Codes

Topic starter

Hello, 

I have a 2014 BMW 428i automatic with 65,385 miles. I have a check engine light for a P00B4/10A001 (permanent) fault code. I have replaced both coolant sensors (right side of radiator and top near plastic cover). Voltage seems to be in normal range. It warms up to 204 F and usually stays between 194 - 200. Live data looks good. No rough start, no idle issue and still getting about 32 mpg.

Thanks,

Brandon

Well you'd have to check the wiring and pray it has some kind of a wiring short or loose connection cuz if not odds are it's a computer driver failure in the computer. If that's the case and it runs okay, I would just ignore it
