Known issues on the 2015 320i xDrive. Thirty-three complaints are on record for this model year, and the engine draws the most at 9, ahead of 5 on the electrical system and 4 recorded under fuel and propulsion. Taken together they point at running and starting trouble more than at hardware failure, the kind of fault that answers to the factory diagnostic sequences: fuel pressure and injector tests, ignition and timing checks against the specified values, and the wiring diagrams that show every sensor and control module in the path.
