2008 Mini Cooper s
I have a 2008 Mini Cooper S (R56)
L4-1.6L Turbo (N14) customer complaint is mil illuminated stored DTC’s
2885 boost pressure control deviation, plausibility cannot find Any information on code need help thank you
sorry for the limited info checked Inwc on crankcase around 16.5 in wc converts to 41 millibar smoked engine no leaks found vehicle acts like it stumbles at times feels like a misfire
2885 is the Hex code which translates to SAE code P1297 essentially a boost pressure too low code. Can you drive the car and graph boost pressure values?
What have you done?, we need more info, a quick google search has tons of info on that code, did you performed health scan, have you test drive the vehicle, any driveability issues present, a quick visual inspection of vacuum hoses oil soaked, leaking? have you smoke the intake? what service information is your shop providing you, I can't help you if you post has lack of info
Thank you for the help I’m sorry for the vague description vehicle showing misfires on every cylinder while in park at idle smoke tested for leaks found none checked crankcase 41 mbar at idle .
can you please provide the fuel trim and fuel pressure data? It is tough to help with such limited info provided.
Check valve cover for internal leak .
Checked with Dwyer 425 digital nanomete 16.5 inwc at idle converts to 41 mbar
Then check blow off valve it ruptures
This may help as is common with modified Minis. jmtcperformance.com/publications/m…
Check for collapsed or faulty hoses to vacuum pump.
I want to genuinely thank everyone for there time and expertise sorry if I know I did not provide enough information for further diagnosis on this vehicle i found a ruptured diaphragm on the diverter valve (bypass) at the Turbo causing a 2885 boost pressure control deviation, plausibility which is one of many components that can set this code thank you all
