What is the reason why BMW's oil measurement 15 cannot proceed?

BMW's oil measurement 15 cannot proceed probably because the oil level sensor is faulty or there is a system issue. It is recommended to go to a 4S shop for a computer diagnosis. Relevant introduction about BMW is as follows: Brand Introduction: BMW (abbreviation for Bayerische Motoren Werke) is a German automobile brand under the BMW Group. It has four model series: i, X, Z, and pure numbers, as well as series like 2 and 3, and the M series (BMW's official high-performance modification department) based on improvements to each series. Logo Meaning: The B.M.W. in BMW's logo stands for Bayerische Motoren Werke (Bavarian Motor Works). The colors and combination of the logo come from the state emblem of Bavaria, where BMW is located.

I've encountered similar issues several times. As an enthusiast who frequently tinkers with cars, the most common reason for BMW's oil level measurement getting stuck at step 15 is when the vehicle isn't parked on a completely level surface, or when the engine temperature isn't optimal before initiating the check. BMW's system is quite sensitive - if there's even slight ground inclination or if the engine is too cold/hot, the sensors will interrupt the measurement. Additionally, occasional glitches in the onboard computer software might occur; try restarting the iDrive system by holding the volume knob for 10 seconds to reset. A more troublesome scenario would be a loose oil level sensor or corroded wiring connection - last time I opened it up for inspection, I found some corrosion on the connector. For a permanent solution, it's best to connect a diagnostic tool to read error codes rather than forcing repeated operations that might cause damage. If all else fails, visit the dealership - their technicians have professional equipment to prevent minor issues from escalating into major repairs that could harm your vehicle.

As a long-time BMW owner, seeing Error 15 during oil level measurement can be really frustrating, especially when you want a quick reading right after parking. From my experience, the key is operating under correct conditions: the vehicle must be parked on absolutely level hard ground, with the engine running for a few minutes to reach temperature before shutting off, then waiting for a brief cooldown before starting. I've encountered system freezes when the ground slope was too steep or temperature wasn't balanced. The sensor might also give false readings - cleaning the engine bay could help. Another possible cause could be interference from headlights or AC being on. I recommend resetting vehicle settings with the original key. If this happens frequently, it might be time for regular maintenance or even considering a replacement - spending some money could save you headaches.

From a mechanic's perspective, a 15-step BMW oil measurement failure usually indicates unmet basic conditions. First, ensure the car is parked level and the engine is warm, otherwise the sensor won't send signals. Hardware-wise, check for loose or water-damaged oil level sensor connectors, or aging wiring harness shorts. For software errors, disconnect and reconnect the battery negative terminal. If you're handy, first check the ground and temperature yourself, but avoid tampering with the sensor to prevent damage. If that doesn't work, visit a professional shop to scan for trouble codes - early intervention prevents major issues and saves money.
