Following the last engine fault light, www.xcar.com.cn/bbs/viewthread.php? tid=99658593&page=1#pid1025841277. After a thorough investigation at the repair shop, I don’t know if there is a real problem with my character or if I won the big prize!!! A gauze was put into the turbine, causing damage to the blades. It was too expensive to replace it with the original factory (the new original factory Mercedes-Benz warehouse shipped 15500 yuan). However, a friend helped buy the car dismantling and refurbishing parts (the goods that a friend helped get are guaranteed for 1 year, and the price of car dismantling parts on idle fish ranges from 800 to 4,000 yuan. As a layman, I don’t know the depth and I dare to do it). Currently, I have been driving 600 kilometers normally, and everything is normal.
Regarding this piece of gauze, the repair shop seriously suspected that it was left behind by the 4S technician during the claim for extended warranty expiration in February 2022, because the number of kilometers at the time of the claim was 117000; the claim was replaced with the oil separator and three machine feet. Since the engine was lifted out and replaced by a car in a 4-day drive, I wanted to remove it anyway and planned to clean the carbon deposits in the cylinder in the store. Coincidentally, the dry ice machine in the store broke; May 22 (123000 kilometers) When cleaning walnut sand at Michelin Chijia Store, I found a ball of gauze in the exhaust pipe at the lower end of the air filter. I didn’t care after taking it out. In the past two years, the high speed has been mostly used. After claiming compensation, it was found that the fuel consumption was higher than before. Higher, the power was slightly attenuated, and nothing else was abnormal. Until the 150,000 A insurance was done before the Spring Festival, it was discovered that there was a small amount of oil in the air filter box on the same side and the engine fault code was reported in mid-March this year. When he felt that something was wrong, he found this friend (former 4S technical manager) to help him conduct a thorough inspection. This man’s judgment was that he claimed for damage to the turbine caused by the gauze left behind at the foot of the machine was not cleaned up. Please consult the two moderators. There was no video for evidence collection of gauze shipped two years ago, and now the damaged photos have also been posted to 4S. Can you claim compensation from 4S? (The Wenfeng Benz 4S store next to the East Bus Station of Qingnian East Road, Nantong City, Jiangsu Province, must pay attention to Nantong riders in the park!!!)
The specific expenses for this time are as follows: 3500 yuan for turbine car-dismantling parts; 750 yuan for right swing arm (Renford); 500 yuan for exhaust pipes and pressure sensors; 90 yuan for two cans of cold media; the store owner personally carried out the continuous disassembly and installation for a whole day, and the working hours cost was 2000 yuan. Report completed!

The endoscope saw that the turbine blades had been damaged

Could you please Yan Ban and He Ban take a look at the original version of this valve?

Comparison between old and new

It still seems good to demolish and renovate cars

The arrow is the price of the turbine 4S, and the channel price of the owner of the new original parts store is 15500 yuan.

That’s where the turbine was damaged

Every time I watch it, I feel sad

Installation instructions that came with the turbine

The packaging is still in place

Compare it again

The removed one obviously leaked oil
