2011 bmw 3281 n52 mass air flow sensor problems

There are 3 key signs that may indicate it’s time to examine your MAF sensor. This causes the engine computer to miscalculate the amount of injected fuel, causing additional damage to your engine. A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. 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.The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. 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.
