22 models were modified second to 530li first guarantee

August 3, 2024

Coordinated in Shenzhen, the 22 models were second modified to 530li first insurance, and they traveled 9900 kilometers. Today, I asked my technical brother that the factory was 5.25 liters of 5W-30. Mine was a three-year free maintenance gift from an old customer, including subsequent oil changes at your own expense. 0W-20 is recommended by default for 4S. 0W-20 is divided separately, and 5W-30 is drawn from large cans. My brother suggests running 0W-20 in urban areas for ordinary models and 0W-30 for M series, which is enough. If you travel in the city, you can change every 10,000 kilometers.

After changing, the gears are light and the throttle response is much improved, which can be clearly perceived. The shifting speed of the 1122 system is above 2000 revolutions. It used to be a bit dragging, but now I can hardly feel the momentum of gear switching.

The abnormal noise of the skylight could not be solved. After cleaning it up and applying lubricant, the cure was not the root cause. The cure was to change the car.
