BMW Repair Questions? Ask a Mechanic for Answers ASAP
I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
you have asked: "would it be possible to test the pressure switch and force it to work or does it seem like another error"
the answer to your question is no, there is no way to test the pressure sensor without a factory BMW scan tool, there is no way to force it to work, and yes it seems like another error.
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
