P12BA Engine Code

Post by baby-z4 » Mon Mar 07, 2022 7:21 am

Hey everyone,
A few days ago I got the P12BA check engine light code. I reset the code and after approximately 300 miles it came back on. I have a 2010 BMW Z4 30i. I cleaned the MAF and MAP sensors already. Any ideas about what this code means and what could cause it?
P.S. My car starts slow (slow crank), first I thought it was the battery but the battery is in good condition. Now I started to think about the starter. Also, it leaks oil from the valve cover gasket. Sounds expensive :/

Change your Map sensor. After that test your injectors.

Update: First I tried to clean my MAP and MAF sensors, it didn't work but then I changed the MAP and the code is gone. The problem was the MAP sensor.
