A few days ago, I used E-altar to consult mini countrymen about replacing some parts that traveled 100,000 kilometers away. I went to replace the thermostat and the broken reversing radar the day before yesterday. They all bought original parts at Benbao in South China. That shop is very reliable. The parts owner helped find a store in Kunming that specializes in BMW Audi. It was quite meticulous. When conducting an entire vehicle inspection, it was obvious that the maintenance technician was very familiar with this niche car.
The cabin is very small, and it is not easy to disassemble and disassemble parts.
The removed thermostat showed obvious aging and leakage of the plastic.
I carefully compared the old and new thermostats. Original parts are made of anti-counterfeiting with matrix dots in some very subtle places that are not easy to notice. Newly purchased original parts also have anti-counterfeiting treatment in these details. The parts suppliers recommended by the forum are still very reliable.
There are such gradual plastic matrix dots in different locations on the original mini parts that are not easy to notice. Compared the newly purchased accessories, they matched one by one.
The brand new thermostat, looking at the number, has been updated for a generation. The boss said it should be an improvement for more than 10 years.
This is a small inductive reversing radar, about the size of a thumb. This generation of mini is the last generation to retain a purely mechanical feel. The dashboard also has pointers, and it doesn’t even have Bluetooth. There is no reversing image, the radar is just a toot, and electronic accessories are ancient and simple products. There is no technical content. At that time, the 4S store issued a quotation that was more than 10 times after the inspection. After reading the quotation, I smiled at the after-sales service of the 4S store, but I was running with 10,000 alpacas in my heart. Car owners who drive mini are really too easy to be treated as silly leeks (thanks again to the strict version and drivers of E-Tan)
Three hours to replace the thermostat and radar. I asked the technician to use an endoscope to look inside the engine. As shown in the picture:
Condition of cylinder 1. This is a 1.6T four-cylinder turbocharged engine. Forgot to tap the spark plug, the burning condition is pretty good. ps. Fuel consumption is slightly higher now than before. It was originally 7.1, but now it is 8.3.
The technician said that there was still a little too much carbon deposition, and what kind of “pulse washing carbon deposition” was a kind of liquid medicine to wash the cylinder. I don’t know anything about this. Is it necessary to clean the carbon deposits in the cylinder at present? Can this potion be used for cleaning? Is there a risk of washing out?
Thank you to Yan Ban and Hao Ban for occupying the precious land again

Moderator Editor, this is the latest homework of the landlord. She used walnut sand to clean the carbon deposits, and the results are very satisfactory: www.xcar.com.cn/bbs/viewthread.php? tid=99727895 。
