Carbon deposit in the washing tank of Siaisi Store

September 2, 2024

The reason was to prepare to clean the carbon deposits in the tank. The Siasi Package was 699 to clean the tank, so I made an appointment one day in advance and went to Siasi Store. This time, I changed it (the shop that bought a car is the largest in the area)

Departure time, reservation 13:30

After arriving at the store, pre-examination and triage are on the shelves

Siisi Store has just been renovated and is not much different from the previous layout. However, the SA workstation has been cancelled and the tablet has been taken directly to discuss projects with customers.

After experiencing the new W223’s S450, it is much better than the 213 in terms of space, but it is not much different from the 212. I have my own dirt, but the interior materials are much more luxurious. It is a large screen in front that replaces all physical buttons. I don’t like it very much.

First, the ignition coils and spark plugs of the four cylinders were removed. At this time, an accident occurred. One of the spark plugs accidentally fell off and fell on the engine guard.

Their cleaning method is to use this detergent

Then push it out and lift it. It was installed at the door before, but it was not put on the workstation. During the Spring Festival, the workstation was relatively tight.

After draining the oil, pour in the detergent

Finally, the detergent was poured in. After the detergent was added, the air gun was used to blow it on it. Finally, the spark plug was put back on, and the original reset was applied.

After giving feedback on the fact that the spark plugs had fallen to the ground, SA asked the leader. My request was also very simple. Help me replace four spark plugs or I buy them myself, and then help me install the spark plugs (installation cannot be charged)

But after entering the workshop, more than a dozen technicians came to my car, shouting and shouting that it was already good to change it for you. What else do you want? and other threatening statements. Screaming everywhere, as if they wanted to compete louder with me, and even slapping the tool cart, which was aggressive. For personal safety reasons, I immediately left the workshop. I gave feedback to their leaders that the after-sales service manager said that it was impossible for me to replace the spark plug, and that it would be a violation of regulations to help me install it, but decided to exempt me from the bill. I can only do it.

After that, due to personal safety considerations, I did not enter the workshop

This spark plug fell. Is there any problem whether it will be damaged? Whether to replace all four of them together? I am still considering this issue. The basic report for this maintenance is completed.
