On the afternoon of April 5, the car was just finished and parked in the basement. When the engine was ignited again less than three minutes after the engine was stalled, only a squeak of current was heard, but the engine was not started.

The instrument display is normal and there is no fault code. In a trance, he thought that he had not turned off the engine just now, so there was no reaction when he started it again.

Check again that there are no problems with the gears and instruments. Now it’s definitely not going to start

Opening the cabin for inspection, leaning on the wheel side to check the underbody, and changing each gear one by one, no abnormalities were found.

Open the forum and use the search function. Relay problems, gearbox problems, and key-inserted ignition module problems have been eliminated one after another.

Ah, there is a high probability that the starter is broken.

I contacted the nearest specialist shop and found that the boss I met happened to be there. Because the distance was only 700 meters, I immediately went to the car to check and knew that there was a high probability that the starter was broken.

The road assistance provided by buying car insurance was finally used this time.

After arriving at the store, we started diagnosis, and removed the starter on the shelves. After testing, it was confirmed that the starter had a problem. We waited for the starter to be delivered on errands to arrive and directly installed it.

1. Starter failures usually come without warning;

2. The M271 engine starter is fast and convenient to install. It can be replaced by removing the transmission guard;

3. Original starters are expensive and generally need to be ordered from 4S or Mercedes-Benz;

4. This time, the replacement is also the same model sold in the “Mercedes-Benz Home”;

5. Because I still had to use the car the next day, I didn’t have time to buy it at the “Mercedes-Benz Home”, so I asked the specialist repair to arrange it. Finally, the installation and test run ended. It was almost 8 o’clock in the evening, and several surrounding auto repair shops were almost closed at 7 o’clock in the evening. The total fee for specialized courses is 1200 yuan. The same starter is 650 yuan for Mercedes-Benz Home.

6. The life of the starter is the number of starts and has no absolute relationship with the number of kilometers. I ran more than 14W kilometers and experienced a starter failure for reference.

7. Although the starter failed this time, the specialist repair shop was very close and the trailer master arrived in 17 minutes, making the repair very smooth. It can be said that the time is right, the place is right and the people are right. If one or more conditions are missing, the maintenance cost and waiting cost will be even more. Therefore, for vehicles that may need to replace the starter, it is recommended that the owner buy a starter and place it on the vehicle. It is small in weight and size. Once a problem occurs, as long as there is a lift or a maintenance site with underground grooves, the replacement can be completed.

It has been less than a year since the engine and gearbox oil seals were replaced, and they began to leak again. Alas, when the gearbox oil is changed again after waiting for 50,000 kilometers, let’s change the oil seals again. When replacing this oil seal, remember to strictly follow the wis. The steps and special tools cannot be sloppy. Otherwise, it will be like my last repair. The first two times were removed in vain, and the last time was considered to have professional tools. It took a total of five days after three attempts. But even so, it’s seeping again
