After 9 weeks of running, the riders who went to the altar to wash the inlet were clean and itchy in the heart of the attack of obsessive-compulsive disorder. 5.1 after the single leisure also has nothing to do, in the forum consulted a dry ice please clean the combustion chamber by the way + a walnut sand cleaning inlet, about it!
9: 30 a.m.:
1. Dry ice cleaning combustion chamber:
I’m sorry I forgot to take a picture.. Describe it roughly.
Remove the spark plug with an endoscope, most of it is a thin layer of brown carbon deposition, the middle round part of the piston also shows metallic luster, the edge part is relatively thick, and some of the sunken parts on the cylinder have been filled with carbon deposition.
The cleaning process was rather tortuous, and the labourers repeatedly used a large box of dry ice, but there was still some places that could not be washed, because there was an angle between the spark plug and the cylinder, so they tried several pipes in their store, and there were still places where the lower piston could not be washed. The top is shiny. I can’t get it for more than three hours. It’s pretty much like that.
I had a meal at noon and ended at about one o’clock.
2. Walnut sand cleaning intake channel:
This should be more mature, take apart the intake port to see the carbon accumulation is simply. Send it to my buddy, he says it looks like booger nostrils. Don’t delete me on the strict version. The view of the innermost two vats was not very good, and the small labourers spent a long time blowing with walnut sand and scraping with tools, and spent the whole afternoon. After washing, I am in a good mood!
During this period, some walnut sand flew out of the cabin, and I don’t know if there is any problem.
It ends after three o’clock
3. loading and commissioning:
The biggest headache came. After a whole day, I thought I could finally go home for dinner. Today, I arranged a meal on Mother’s Day. As a result, the car was loaded, and the staff did not go out for the test drive, so he shouted: fault code, eliminate it! The clerk took the computer to talk about trifles, and then it was over. Then: alas? Why can’t it be eliminated? I’ll try again. Alas, it still can’t!? Go back to the furnace and recast.
Error: “the solenoid valve of the crankcase partial load ventilation system is short-circuited to the ground, check Y58 Universe 2 parts.”
According to the xentry prompt to check, plug voltage valve body resistance what is no problem, electrified valve body works normally. Reseat the plug and still report an error.
During the consultation for 4s, an oil-related plug in the lower part of the engine will also cause this error and the attempt will be fruitless. Took a new valve and replaced it to no avail.

This part is directly controlled by ME, unplug the computer to check, at this time! Found it! There is the same problem found in the jar when a rider is washing walnut sand! Plug computers are full of oil! The quantity is a little less than that car friend. I don’t know what kind of oil it is.
At this time has been tossing to eight o’clock in the evening, directly consult the driving computer maintenance, said that this situation is very common should be caused by short circuit. I’m speechless, too. The car is directly there for maintenance.

Take a taxi home and wait for my mother and my new mother’s wife to have dinner. My wife said that the first Mother’s Day was so sad.
I didn’t pick it up until it was repaired all day on Monday.

It should be the happiest experience to pick up the car on Tuesday, wash the car and avoid the muddy rain on Monday in the imperial capital.

I drive slowly, but I do feel more comfortable after washing. I don’t know if it has a psychological effect, but I feel better after washing it.

In this experience, if the same car user finds that it is difficult to eliminate the unexplained fault code, it is recommended to check the engine control unit (ME) to see if there is a large amount of oil causing a short circuit.
