The safety issue is the possibility of an engine fire and BMW's negligence in taking responsibility for the manufacturing flaws, especially when so many owners are having problems with these issues starting early at 40k miles.BMW E93-series All Models (316i, 318i, 320i, 320si, 323i, 325i, 328i, 330i, 335i, M3, M3 GTS) Repair & Service Manual 2005-2013Ĭomplete service repair manual for BMW E93-series All Models ( 316i, 318i, 320i, 320si, 323i, 325i, 328i, 330i, 335i, M3, M3 GTS), with workshop information to maintain, diagnose, repair, and service like professional mechanics.īMW E93-series All Models workshop service repair manual includes: This replacement will cost me another $2k+ for a valve cover gasket and oil pan gasket replacements, yet this wasn't made known when I had gotten my oil changed previously. Decided to take a look at my engine myself and noticed oil leaking from the valve cover gasket area and could see oil that had leak on the bottom of the engine bay, now at 60k miles, took it in early for an oil change and diagnosis again due to possible fire if oil spills on mounting struts. These codes weren't showing up on my vehicle. Did research into the issue with other BMW owners which had the vehicles serviced for replacements of vanos, mass air flow sensors, etc. Went back to dealer and stated they didn't find any further issues. Next day, continued to have the same problem. Was told that it was the eccentric shaft sensor/gaskets, battery tested low to include vvt sensors and left pad brake sensor due to wire cut. Took vehicle in to dealership to diagnose issue, oil change. Engine cold start hesitation with vibrations while idling stationary.
