14 Mercedes-Benz E-Class 212 Replace the trunk auxiliary battery ~ Clean the evaporator ~
BarbaraGreen 
9 Today is a sunny day, the outdoor temperature of more than 40 degrees means that summer is coming in Chongqing.
About a year and a half ago, when there was an ECO start-up and shutdown, it was very difficult to get back green, and the startup and shutdown was permanently closed. Since the beginning of this year, there has been a hint of “auxiliary battery failure” from time to time, sometimes driving a car and stopping at the destination. One or two hours before ignition will prompt the battery failure, sometimes the first ignition on the same day does not indicate a failure, and after stopping for a while, the ignition has another fault hint, the symptom is that HOLD will fail, anyway, the hint and non-hint are a bit random. The auxiliary battery will not fail completely, it is very elusive, think about it or change it, it is simple anyway.

Original car battery
10mm caliber hexagonal sleeve ~ ~
Remove the negative electrode first
Remove the exhaust ~ ~
Redisassemble the positive pole.
Remove the battery fixing bracket screw ~ ~
Open the fixing bracket ~ ~
The old battery of the original car on the left, the new battery on the right.
The old battery of the original car on the left, the new battery on the right.
It’s exactly the same.
Spare parts, one more label.
The above is the old battery of the original car, the factory date is 13 years and 50 weeks, the car left the factory in December of 13 years, matching, firm for 10 years, really have you, that is to say, the main battery has not been changed, the voltage of cold car is 12.5V, it is still healthy, it is really good for you, this is also the reason why I continue to use the original factory, it is too long-lasting.
The battery below is also 24 years and 11 weeks old, and it is also fresh.
The battery below is also 24 years and 11 weeks old, and it is also fresh.
The old battery, for ten years, the positive and negative electrodes are still shining brightly, just like the soles of the feet, where there is no sun or light, it is just a little white.
The only difference between the new battery is that the new positive and negative poles are dimmer.
The new battery is in place.
Next is the problem I mentioned in my last post. Near the 1500 turn uphill, there will be a noise. The cold car is more obvious than the hot car, the uphill road is more obvious than the flat road, and the downhill road is not. Two sets of machine feet have been changed, but they have not been completely solved. It’s numb.
In the first half of the month, I accidentally picked up something in the trunk, and the child helped me start the car in front. At that moment, I found the disease.
In the first half of the month, I accidentally picked up something in the trunk, and the child helped me start the car in front. At that moment, I found the disease.
It is the exhaust decorative cover and exhaust pipe on the lower left that snap together due to the vibration of the exhaust pipe when starting and filling the throttle.
I went to the repair shop early this morning, took the tools, lifted the car, took off two 30-like hexagonal screws, and saw the root of the problem. The exhaust decorative cover was deformed in the position where the circle was drawn in the picture, resulting in a distance of less than 5 mm from the exhaust pipe. As soon as the exhaust pipe vibrated slightly, as soon as the throttle was added, the two began to crack, and I would feel the abnormal noise of Dada. Without decades of social experience in beating, it is almost impossible to find.
Then the right rear decorative cover also loosened the screw adjustment of the lower position, the two exhaust decorative covers can be adjusted back and forth by about 1 cm, and I adjusted them to the innermost position, so that the distance between the decorative cover and the tail bright strip is the smoothest, and the space of the innermost cylinder and exhaust pipe of the decorative cover is also slightly larger.

Today, driving all the way back, I feel that the shift has been smooth ~ I have tried numerous uphill 2je 3 gears 1500 rpm, and garage low speed 1 gears 1500 rpm. I don’t have any feeling at all. I’m really happy to solve a big problem, a big problem that bothers me!
I tested the ET5 two days ago. The stampede strength of the throttle brake, the linear brake and the power on call are really the feeling of the unity of man and car. I feel very in place. It is easier to drive than other domestic trams of the same level. The training is more German, that is, it feels too little to have a range of about 400. consider it again after more than 500. it is certainly impossible to say ~ ~ city driving lane-changing automatic parking surpasses me as an old driver ~ ~

This is the weight of the old battery of the original car, which is the same as the data provided by the car friends, 5 kilograms! ~ ~
The voltage is also normal, it is estimated that the capacity is not enough.
Next is the photo of the evaporator cleaned before, because there is a fart smell every time I drive for about half an hour, no matter how long it takes to drive every day, it is very embarrassing to change the air conditioner filter element, and it will smell sour in less than two days. The evaporator must be cleaned.
Because from time to time to jump out of the “traffic sign auxiliary” fault prompt, before the installation of CARPLAY, may be due to the wiring harness connector is not neat, resulting in poor contact, so while cleaning the evaporator, take advantage of the removal of some more, everything is normal after recovery
This is easy to disassemble.
After the armbox is removed, it will be easy to operate.
The blower doesn’t care about it, it has been cleaned before.
I saw the co-pilot’s airbag for the first time. I hope it didn’t fail.
Installed carplay~~~
Unwittingly, it has been used for almost two years, cutting off all the useless wire harness and refreshing this thing, there has never been a problem.
The front filter element of more than 1000 kilometers is so black, alas, my lungs.
Accidentally found that ignition in the garage, unexpectedly will automatically cycle, this will be closed, the logic is good ~ ~ by the way also wiped clean ~ ~
Kill the poison in the outside inlet and refresh the air.
The process is very fast, I will briefly explain that I bought Mercedes-Benz disinfectant online. After all, alcohol antivirus can only be used as an assistant. Through the endoscope and pneumatic spray gun, the evaporator is washed with disinfectant, and the spray tube goes directly into the filter element of the air conditioner. My friend in the repair shop helped me operate it. I was so excited that I didn’t take pictures, and vigorously developed the condenser in front of me.
Some friends take the hole in the evaporator sensor to wash. That place can wash the back of the evaporator and the place where the water comes out. It is also the most polluted place. I will wash it slowly when the weather is cool.
The minimum temperature of the outlet is 3.2 degrees, and the air volume occurs in the case of gear 2.
In my photo, this is the lowest temperature of the air volume in the third file ~ ~ the higher the air volume, the higher the temperature, which is very normal.

Attach the seller’s information.
I bought a large bottle, using 300ml at a time, once a year.
Thank you for your attention. Finally, I would like to thank the Yan version of the various technical posts, and the essence of the car friends posts, so that I can successfully complete so much preparation work today, I am standing on your shoulders to see as far as you, the word is poor, thank you! I hope it can provide some reference and help to the cyclists who are still sticking to Xiao Tu Ben without changing cars!
