How to Solve the Jerking Sensation in BMW?

If you want a smooth ride, you can gently press the accelerator pedal at the appropriate time, and the transmission will automatically upshift, resulting in a weaker gear shift jerking sensation. Persistent dirt and impurities have accumulated inside, especially within the valve body, forming blockages that prevent effective regulation of oil pressure. Check if the transmission temperature is normal. If not, inspect the transmission cooling system. If the cooling system is functioning properly, reprogram the transmission computer. Examine whether the internal valve body of the transmission is damaged, and replace the transmission fluid, especially for older vehicles.

I just experienced this issue - the jerking of BMWs at low speeds or during gear shifts is really annoying. Most of the time it's a transmission problem, especially in older cars where the transmission fluid hasn't been changed for too long, causing degraded fluid to result in rough shifting. First check the transmission fluid level and condition - if it's black or has a burnt smell, immediately replace it with the manufacturer-specified fluid. Also don't ignore engine carbon buildup, particularly in direct injection engines where excessive carbon affects combustion efficiency - walnut shell blasting every 30,000 km works well. The transmission software also needs updating - many dealerships can refresh the module for free. Finally pay attention to driving habits - stomping on the accelerator worsens the jerking, while smooth acceleration can alleviate the problem.

My F30 has started to show noticeable jerking after driving over 70,000 kilometers, and I've explored quite a few solutions. The focus should be on checking the transmission and fuel system. It's recommended to first read the fault codes to confirm if it's a serious issue. Transmission fluid should be changed at least every 60,000 kilometers, and using ZF genuine fluid is highly recommended. Clogged fuel injectors are also common, so remember to replace the fuel filter at the same time and use a reliable brand of additive to clean the fuel system. Worn-out spark plugs can cause poor ignition, leading to sluggish acceleration. Regularly replacing them with NGK iridium ones works well. Also, a dirty mass air flow sensor can be improved by simply spraying some cleaner. If you experience significant jerking during cold starts, try warming up the car for a few minutes before driving.

The key to solving BMW's jerking issue lies in three aspects: engine, transmission, and driving habits. First, clean carbon deposits, especially using dry ice cleaning for the back of valves which proves effective. Then, ensure transmission fluid is changed on time - the safest approach is having it done at a 4S dealership along with a software update. Spark plugs must be replaced at 60,000 km using OEM-matched models. Driving-wise, avoid sudden throttle inputs at low speeds and utilize manual mode for better gear control. Maintain proper tire pressure as uneven pressure affects power delivery. Fuel quality matters - avoid cheap gas from unknown stations; adding a bottle of fuel system cleaner monthly helps maintain clean fuel lines. These cumulative small adjustments bring noticeable improvement.
