Good day everybody. Glad to join the group. Feel in love with Mini when I rented one in Germany many moons ago. Actually the exact same model down to the color as the one I own now. I have a black 2010 S N14. Purchased in Kansas City even though I live in Chicago(Amazing how difficult it is to find a manual). I joined because I have some mechanical as well as upgrade questions. Here is a list of what I have had done since I purchased it with 70,000 miles. It now has 77,000 miles. New tires Fixed drivers heated seat oil changes of course thermostat housing and thermostat oil cooler seal turbo oil line coolant flush brake fluid flush new intake manifold(old one was slightly melted so the car overheated at some point replaced almost all engine sensors(2 MAP, solenoid, crankshaft, and 2 oxygen) new valve cover new spark plugs high pressure fuel pump gasket Walnut blasted intake Nm air charge pipe And here are my issues that I'm trying to resolve. Slight vibration at idle and poor mileage(20-30mpg). I now have a P129E - Manifold Absolute Pressure Minimum Pressure Implausible code after installing the new MAP sensors. Tomorrow I will swap it with the old sensor to see if the new one is faulty. No other codes. OBD live data shows upstream oxygen sensor(O2S11) bounces between -.01 and .01 which I believe means super lean as it is supposed to be between .45 and .50. downstream sensor(O2B1S2) stays pretty much at .80. There is a oily foam under my oil cap which only goes away after long highway drives. It is not on the dipstick and the coolant level hasn't changed so not a coolant leak. I tried to measure crankcase pressure but only have a gauge in InHg which showed 2.5 and did not move from idle to full throttle. 2.5 InHg converts to 84mbar but the N14 is supposed to have 38mbar pressure. I have ordered a mbar manometer to confirm this. So I am thinking a vacuum leak but I cannot find it anywhere. Any advice or opinions?
