In June 2017, I purchased a second-hand F18’s 2014 525Li luxury design set from 4S, 55000 kilometers, 360,000 yuan only, and 13,000 yuan insurance.

In the summer of 2017, I set off from Suzhou to Putuo Mountain

2017.11 We set out for Suzhou and went to Ningbo. About 600 kilometers back and forth

At the end of 2017, the 4S senior technician brother I met opened his own repair shop from the store, and has hardly been to 4S maintenance since then. Replace the oil filter every 7000 kilometers or so and upgrade the original factory 0W30 from the original factory 5W30, which costs about 600 yuan per time.

2018.6, the mileage reached 70,000 kilometers, and the original rear wheel brake pads (TRW) and original transmission oil were replaced. There is no cheap way to add ZF oil here, although it may not make any difference… The total cost is more than 7000 yuan. This oil replacement process is quite complicated and has a strange taste.

In May 2019, more than 80,000 kilometers, replacing belts, tensioners, thermostats, and coolant cost a total of 3000 yuan. I have seen photos of several F-chassis N20’s 3 Series and 5 Series lying on the road for 100,000 kilometers without changing belts, but it is still necessary to think about it.

The original owner replaced the waterless coolant. Its boiling point is much higher than that of the original coolant. Although it protects the engine, it accelerates the aging of the waterway. At that time, my brother told me to be mentally prepared for leaking water pipes. Indeed, as he said, it laid the foundation for future failures!

At the end of June 2019, the first long-distance driving tour began

Starting from Suzhou, you will pass through Qiandao Lake, Nanchang, Changsha, Wuhan, Hefei and back to Suzhou, which is 2260 kilometers round trip. The car is in good condition and it is comfortable to drive without any problems!

Before the epidemic in January 2020, Suzhou set out for a self-driving trip to Fuzhou via Taizhou, a round trip of 1680 kilometers.

Fuzhou is a city that very much wants people to visit for a second time. The climate is pleasant, the history is long, and the food is rich. The trip to Fuzhou was also the last long-distance self-driving tour of F18.

2020.11。The accelerated aging of waterways mentioned earlier has indeed come true. The water pipes near the turbine cracked and most of the coolant leaked

Remove the turbine replacement water pipe

The machine foot pad is seriously aging

Finally, the brother said that the water pipe repair cost 3500 yuan, but selling the car to him to repair the car would be free. After considering it, the mileage of the car reached 103000 kilometers, the left front wheel was obviously worn, and the floor mats were seriously aging. Oil seepage in the oil pan is obvious, which is a common problem for N20 engines. Many factors combined, and I decided to sell it. In the end, he also gave me a price much more than the market price, 220,000, which was a win-win situation ~
