RE: F20 N13 - 15N2 supply problem - 1B5302 error - KristjanL - 02-25-2023 Might be a ground problem or a bad connection somewhere, if you checked the complete circuit and are sure that these are okay it is a bad component in the circuit or a faulty output. Unplug everything that uses this output for power and start plugging connectors one at a time and always check for voltage on 15N. Should be able to locate the faulty component. RE: F20 N13 - 15N2 supply problem - 1B5302 error - djoes16 - 02-26-2023 Ground is from dme and i check resistance - is Good. I unplug all component and still have error on ista but status is „unknown” or „not exist” but on idrive still have idrive of Drivetrain RE: F20 N13 - 15N2 supply problem - 1B5302 error - modernm69 - 03-14-2023 15N_2 Replace Vanos solenoid in Engine oil crank .
