Where is the front cylinder position sensor of Dongfeng 307?

4S shop, No.49 Xingshikou Road, Haidian District, Beijing! (307- Red) Beijing Han Peng Trading Co., Ltd.: My new car cost 4,800 yuan in half a year. I changed the right fender of the bumper in Han Peng 4S store. I went to pick up the car three times, but the paint didn't spray on me. I got angry the third time I picked up the car on the spot. Let me change the bumper again and refund the bumper money. Bring it back to the car that night and exhaust the alarm the next night! Finally, I went to another 4S shop to show me the oil tank, nozzle, air inlet, oil pump and oil pipe, all of which are sticky substances like coffee (nozzle and oil pump cost more than 3,000 yuan to clean and return) and stick to the car wall. I asked several teachers that it was broken and said that I must have offended others. Fill my tank with stuff ... Shit! State-owned enterprises finally approved it without evidence (I asked several mechanics, and this substance would be finished if it didn't run 10 km in the fuel tank, and there would be problems if I ran 15 km. I haven't refueled before, so please comment on it yourself).

Be careful with your handlebars in case of conflict.

The money I spent

I don't understand. I don't know if they are talking about me.

Han Peng is a grandson. My car was bought there, and the first insurance was made there. When maintaining and changing the oil, they didn't flush the old oil with engine oil, but let the engine burn the oil dry. Think about it, it will ruin the car even more.
