Just bought a 2011 CM all4 and its running in limp mode for 2c01, first start it's ruff with several miss fires codes but once the check engine light turns on it'll smooth out and run good in limp mode. Of course only to 4500rpms. If I clear the codes while it's running only the 2c01 will come back on. When I check rail pressure with my scanner it starts out around 1040psi but after running a couple minutes it'll drop down to 87psi and stay right there. When I map it at first while driving I'll get 1740psi under load but once it decides to quit reading it'll go to 87psi. But still runs smooth and will drive. Previous owner said they've been driving it like this for around 5 months. I'm curious what's the chances of it just being the pressure sensor which I've ordered or is there anything else I should check. Also The front wipers don't work. Checked relays they're good but haven't dove into the wiper motor yet. Thank you
N14 engines and early N18 engines are known for failing high pressure pumps. All those codes listed in your tool are likely related to the failing HPFP. Get a reliable replacement, and move on.
I understand that but guess my real question is would the car still run if the hpfp was really only putting out 87psi and would a failing pump really last 5 months as a daily driver
It should run with low pressure, but I would expect it to run in low power mode. (limp mode) The engine will effectively just barely run and stay out of boost. If you're seeing 87psi on the fuel rail, that would tell me the low pressure pump is keeping the engine running.
