Hello, I have a 2014 F20 116d 2.0l. Bought the car used with a drivetrain malfunction. Diagnostics said the DPF was clogged. DPF service took it out opened it and cleaned it manually, reinstalled it and reset the faults. I was driving it and my RPMs started jumping in idle when the car was warmed up. Diagnostics said there were two faults :245700 and 290900. Took a look at the EGR, it wasnt that dirty. Bought a new exhaust pressure sensor and fitted it and after a while drivetrain malfunction again (it said possible to continue with journey). I didn't reset the codes after the new sensor, is that causing the problem? Thanks in advance!
