There is no oil dipstick in the 5 Series. The engine oil pan is equipped with an oil level sensor, and the oil quantity is displayed on the central display via the sensor. Taking the 2021 BMW 5 Series as an example, it belongs to the mid-to-large-sized car category, with body dimensions of: length 5106mm, width 1868mm, height 1500mm, wheelbase of 3105mm, fuel tank capacity of 68 liters, and curb weight of 1705kg. The 2021 BMW 5 Series features a double-wishbone independent front suspension and a multi-link independent rear suspension. It is powered by a 2.0L turbocharged engine, delivering a maximum horsepower of 184PS, maximum power of 135kW, maximum torque of 290Nm, and is paired with an 8-speed automatic transmission.

I've been driving a 5 Series for almost ten years, and the newer models basically don't have physical oil dipsticks anymore—they've all been replaced with electronic monitoring systems. To check the oil level, you need to start the engine, let it warm up for a few minutes, park on level ground, and then operate it via the buttons on the steering wheel or the iDrive system. Based on my experience, you should navigate to the onboard menu, find the vehicle information or service options, and select the oil level detection function. The screen will then directly display the oil level status. If it shows low, don't panic—just open the hood and add the specified viscosity oil at the oil filler port. Remember not to check on a slope, as the reading won't be accurate. For routine maintenance, it's best to check once a month to avoid engine wear due to insufficient oil, especially before long trips—always check to ensure safety. If you encounter any issues, you can refer to the owner's manual or consult a specialized repair shop.

As a car enthusiast, I've studied the oil system of the 5 Series. For over a decade now, the physical dipstick has been eliminated across all models. In terms of location, it's been replaced by electronic sensors in the engine compartment. The checking procedure is straightforward: Start the engine and let it run for a few minutes until reaching normal operating temperature, park on level ground, turn off the engine, wait 30 seconds, then access the engine oil option through iDrive or the instrument cluster menu to check the reading. If the display shows abnormalities, it could indicate sensor malfunction or actual oil shortage. Be cautious when adding oil – avoid overfilling to prevent damage to seals. It's recommended to use the manufacturer-specified oil grade. If unsure, measure the oil pan manually with proper tools. Regular checks can extend engine life by tens of thousands of kilometers.

Oil level checks are crucial for 5 Series owners, as modern models don't have physical dipsticks. You need to use the onboard electronic system to check oil levels: After starting the vehicle, operate the iDrive controller to navigate to the vehicle settings menu and select engine service check. The system will display OK or indicate if top-up is needed when parked on level ground. Remember to warm up the engine to avoid cold-start misreadings. If oil level is low, promptly add the appropriate amount of oil through the filler neck - don't wait until the warning light comes on. Make it a habit to check weekly to maintain optimal engine performance.

For 5 Series beginners, checking the oil level has now become electronic. Operation method: Park the car on level ground, start the engine and warm it up to normal temperature (about 85℃), then turn off the engine and let it sit for 1 minute. Next, access the iDrive system or instrument cluster to find the maintenance function and select the oil level test. It will provide instructions; if no addition is needed, continue using as is. When adding oil, carefully pour the dedicated engine oil using a funnel to avoid overflow. The key step is ensuring the parking position is perfectly level, otherwise the system may report an error. Developing this habit monthly can help prevent major repairs.

In circles, the topic of oil dipsticks has been discussed. For older 5 Series models like the E39, the dipstick might be located on the right side of the engine bay near the engine, but newer models have electronic monitoring. The checking method: Drive until the engine warms up, then park on level ground, turn off the engine, wait a moment, start the iDrive, select vehicle diagnostics to check the oil level. If it shows low oil, add oil through the oil filler under the hood. Note that too little oil can damage piston rings, and regular checks can save on repair costs.
