Hey all, I've a 2012 R60 (Countryman S). I love it. I won't part with it. It's driving me insane. I started with some rough starts when cold, progressively getting worse. I've read about some of the high pressure pump issues and with 130k miles on the dial, I though it was good time for a refresh. New high pressure pump installed, same issue. I pulled the rear seat up to swap out the sending unit and there was fuel visible on top of the sending unit inside the electrical connector. I figured with the pins/plastic degrading I'd found my issue. Swapped it out, same issue. (Unrelated to rough starting but now my dash gauge reads half of a tank when I'm all but empty. I think it's the wrong potentiometer for the model.) I tore down to the fuel rail to replace the rail pressure sensor and injectors. New injectors, sensor delivered was wrong. Marginally better starts but still low pressure when I shift, or come off the throttle (check engine light on then off). I'm currently trying to locate the fuel pump relay to swap out for a known good. I've ordered a 3D printed intake adapter to give it a walnut shot. I assume carbon's unrelated but anyone who may have other opinions,ideas or advice would be greatly appreciated. I run the Torque app on my phone with a Bluetooth OBD tool. My codes are repeated, switching from pending to historic from time to time. P0087 Fuel Rail/ System Pressure - too low P306F Fuel Pressure drop below minimum P15DF Fuel High Pressure System Cold Start, too low Other than the rough first start attempt (it purrs on second start) as long as I stay out of Sport mode and don't try to pass at highway speeds I'm okay. I know, I didn't follow the golden rule of replacing the cheapest parts first, I went more with the easiest to swap out and ignored price. Any sage advice?
