Spark plug-700 save, now you can not look at the number of years, directly look at the mileage. Since the last time I changed Gang 20000km, I was ready to do his 10000km at least (almost more than 30000, which is sometimes used for the switch with T).
Throttle-more than 700 saved, there is no need
Air conditioner filter element-jd directly fixed, save 380s
Air conditioning cleaning-TBD, I haven’t tried alcohol yet, but it’s only 300 at most downstairs, so the price difference of 460 is saved.
Differential oil replacement-ssss directly do not recommend that it is maintenance-free for life, but according to the strict version recommended or changed, two bottles of oil a bottle of 120, man-hours 100. The total is 340. It saves 1000 compared with ssss quotation.

Nearly 3000 of the above cards are stuck.

The differential oil still had a notebook, and as a result, the master didn’t use it at all. He just came up and said, “you only have two bolts, huh?”. It seems to be quite skilled. Three, five, five, two, three, five, five, three, five, five, five, For the specific oil conditions, see the figure below. Because it is collected in an opaque bucket, it is impossible to observe it at rest. There are several observations.
1. According to the strict version, the whole process visual, instructed to use the torque wrench 50Nm. I did, but we don’t know if the wrench is 50Nm. There should be nothing wrong with it.
two。 Asked the master, and did not provide the first into 0.5L oil and then D-gear idling, but empty directly filled with new oil to leakage. (it’s probably a lot of trouble. )
3. Two barrels of oil are poured into the pump (2L), but only 1.2L is needed. And the differential is not cleaned with 0.5L oil. Hmmmm . Forget it. Anyway, this thing is only changed once every 6w kilometers, and it takes up space to keep at home, and the cost is not expensive.
4. With regard to oil release and refueling bolts, according to the strict version, take the initiative to ask for cleaning + applying sealant. The master cleaned it, but said it was not necessary to apply sealant because the shape of the bolt was tightened to prevent leakage.Then let’s just take a look at it.
5. The master can see at a glance that this oil label is different from the original factory (skilled! (fortunately, I checked, and I remember that the original factory was 75W-85. Fortunately, I checked, the latter number represents high temperature fluidity, generally the higher the better, so there should be nothing wrong with reasoning.
6. Pump oil is directly pumped to the spill, which should be quasi-1.2L. There is no intention to accurately measure the amount of pump.

I feel that the next A guarantee can be done downstairs, which is convenient and saves money. The gearbox oil has been changed for 4w, and it will be a long time next time. We’ll see.

Recently, I have read several posts related to gearbox and specially tested it, and it is true. After reversing into the warehouse, it also turns off the engine directly on the R gear, and the system automatically jumps back to the N gear. Pull the door directly (make sure the car doesn’t slip), and the car automatically hangs the P gear. Advanced, ha!

At the same time, automatic parking was tested. What does hmm say? I can pour it if it can, and I can’t pour it if I can’t. It’s just that sometimes there’s an accident.

Asked the tb store about the latest version of the Audio20 navigation map, but unfortunately there was no follow-up update. I don’t know whether MB has stopped the service of the old machine (only updated to 2019 Universe 2020 V12.0) or whether garmin has stopped its version. It is suspected that the former is because the new car is also available with the simple Audio20, but the map version does exist in 2021 and later (tb can be found, but not compatible with the old car). I didn’t show it in many places when I went back to my hometown this time, but I just saw me plunge into the vegetable field. There has been no follow-up update for a long time, and it will be a pity if we don’t update it.

The rest of the project-strict version of alcohol * + wiper piece replacement. If you do it all over again, it will be leveraged again!
