11 Αυγ 2022 · I replaced the boost solenoid, charge pipe and ran the troubleshoot but the code comes back. I learned that the error can occur as a difference in pressure limit between a few sections of the throttle system. So any boost/pressure leak from a valve cover or a pipe can cause the code.
11 Σεπ 2023 · Fault code 216104 is basically a code that has been generated to say the engine took too long in attempting to start. It's a symptom code rather than the actual issue which is 101F01 and 102002 which relate to a problem with air getting to the cylinders.
I ordered a MAP sensor from ECSTuning.com and installed it, and cleared the codes. The CEL came back on, however the codes had changed to 101F02 and 104302. To me this means that it went from pressure to high to pressure to low.
I just picked up a 2011 X3 35i that is setting a P0112F or 101f01 code. I've checked all the charge air pipes for leaks and everything is sealed up good. The valve cover was replaced recently with a new one so the PCV is not an issue. Both pressure sensors are working fine.
