Elimination of abnormal sound in driver’s door

There has been a noise in the driver’s door for a long time. I always thought that the door screw had fallen off. Every time the car turns, there will always be a knocking sound. It is really unbearable, so I decided to go to 4S to find out the reason. When I arrived at the 4S shop, I briefly explained the situation to the master. There was no doubt that the door panel had to be removed to find the crux of the problem. This is the third time that the driver’s door has been removed. The first time is to replace the exterior mirror, and the second time is to replace the window lifter. The process of removing the car door was still quite complicated, and the young master struggled for a while. After the door was completely disassembled, no screws or other objects fell out. Everyone was very surprised. Then the master used it again and shook the door, but the sound was still there. I took a photo with my mobile phone and found that there was something else inside the...

[Daily car maintenance] After the engine reaches the red line of seven to eight thousand revolutions, will it damage the engine much?

Hello everyone, this is a column focusing on car repair and maintenance. There are car mysteries you don’t know, and it will teach you how to avoid the big pits on the road of car ownership. I believe that not only you but also many people have a certain sense of obscurity about the car aftermarket, which will help you uncover the unknown stories of car repair and maintenance. There is a small loophole in the above problems, that is, it is difficult for current engines to step on the red line while idling in place. Due to the different design concepts of each manufacturer, there are individual models that can be done. Back to the original text, because idling into the red line and running into the red line do not change much for the engine, so I would like to share the impact of the engine after entering the red line. Why do some cars step on the red line when idling is not allowed? Countries have national boundaries and family rules, and cars also have their own restrictions....

Old Sail central control locker maintenance

I don’t know how many old European lockers have been bought, but they were finished in just a few months, especially the Youshi ones. After using them for less than a week, the driver’s door had a slippery sound. It was too difficult to hear. What’s even more funny is that I went to the car inspection in August and was about to go online soon. The passenger’s door couldn’t be opened even if it was killed. The central control locker popped up. That was embarrassing, the mechanical lock couldn’t be opened. In the end, I still came back after the car inspection and removed the interior panel before opening it. So the so-called normal parts bought by a certain treasure are all the same. He simply had nothing to do last weekend and thought of taking apart the original car locker that he had replaced to see if it could be repaired. The problem turned out to be too simple, and the repair was easy to get to the point. Tools needed: two one-word-change knive...

Accidentally inserted, the abnormal sound of the chassis (including the steering gear) disappeared

After two repairs, the steering gear is still ringing after the speed bumps and uneven roads. I have made up my mind to ignore it. Let’s just ring and use it if there are no safety issues. This time, I will replace the front wheel bearings, considering that the car has been over 10 years old and the mileage has reached 230,000 kilometers. Various ball joints, rubber sleeves and other movable parts and buffers are basically aging. Gritting your teeth, and replacing them with new ones, including the lower arm ball joint, large and small rubber sleeves, the outer ball joint of the steering gear, and a tie rod. The ball joint of the front balance bar, the rubber sleeve of the rear balance bar, the rubber sleeve of the front shock absorber, the inner and outer cage of the half-shaft were re-buttered and the dust sleeve replaced. Unexpectedly, the effect was unexpected. The chassis became very tight and tough. There was no loose sound like before when passing through the speed bumps a...

Volvo S90 20,000-kilometer air conditioning filter element replacement

On December 31, 2020, I ended my four-month business trip, took out the new air conditioning filter element that had long been covered with dust, and found the group owner of our Qinhuangdao Volvo Car Club (the little fans called him the leader brother, wait, let’s show everyone whether the leader’s head is big or not.) Come and help me replace the air conditioning filter element. Our Qinhuangdao Volvo Car Friends Club is an officially recognized club. The group is united and friendly, and the group owner has also accepted officially invited training activities, so installing an air conditioning filter element is naturally a problem. First, take out the filter element that has been left for four months Then take out the special screwdriver and watch the group leader perform The old filter element is still very dirty Brother Ning heard the news and came to watch the show It took the group owner less than ten minutes to set it up for me. During this proce...

Warm company, family reunion, but also pay attention to tire safety

As the New Year approaches, the flavor of the New Year becomes more and more intense. People who wander away, no matter how far away they are from home, have to embark on a journey home. Big bags of luggage contain gifts prepared for the reunion occasion. Crossing thousands of miles, not afraid of hard work, just to see the happy smiles on the faces of relatives. It’s great to go home. Eat and drink well and sleep until you wake up naturally without work. But have you figured out how to get home yet? High-speed rail and planes are both places where people gather. This year, we celebrate the New Year on site. However, driving home closer to our hometown is also a good choice. In order to get home safely, we must check the safety of our tires, because tire safety equals life safety, so when the tires have reached a certain life or the tread patterns are almost flat, we must replace them with new tires, and be safe on the road. Go home for the New Year. Classic Mai Rui Bao, very...

Repair the multi-function steering wheel button

It has been two or three years since the up and left buttons of the multi-function steering wheel have been basically unusable. However, you can use the right-down button to press it several times instead of using it. Recently, the OK button in the middle is no longer working. Many functions cannot be set without the OK button, such as speed alarm, answering and rejecting calls, etc., so I decided to take it apart and study it. The last time I removed the steering wheel was in 2013 when I installed the shift paddle myself. Now the technique is unfamiliar, and it took me a long time to get it done. Then I found that the screws on the back of the multi-function button were very small Torx. I didn’t carry such tools on the car, so I had to install them back, but I didn’t install them, which caused the horn on one side to stop ringing.

M271 turbocharged engine replaces Bakelite water pipes, cross water pipes, etc.

I went to change the oil and brake fluid this morning and accidentally found leakage marks on the chassis guard, which I had never seen before. Not sure what the reason was, I immediately went to a Mercedes-Benz specialty shop that I had visited twice. Here’s to commend the newly developed oil change shop. The store is not big and tidy. They are all young people who not only take the initiative to use torque wrenches, but are also willing to listen to the standardized operations on WIS. I plan to replace the differential oil here next time. After a special inspection by Mercedes-Benz, it was determined that it was not the oil leaking from the base of the machine filter, but the Bakelite water pipe leaking. The vacuum pump was normal, but a gasket needed to be replaced. In the end, the antifreeze kettle was confirmed to be in good condition, saving money for the original kettle. I didn’t know what liquid it was at that time, and I was panicked The leakage range is quite ...

In the blink of an eye, 2022 is almost over. A busy year has some happiness and bitterness. This is life, this is life.2022, which was shrouded in the epidemic, recalled with mixed emotions, which affected life, work and other aspects.But we must be grateful. It was the close maintenance and control of the party and the government that we have today.The end of the year is here, and it’s time for your car to be maintained.What I think about changing car oil is this:The quality of any quality grade of lubricating oil will change during use. After driving a certain mileage, performance deteriorates, which will bring various problems to the engine. In order to avoid faults, the oil should be changed regularly according to the use situation. The oil amount should be moderate. When the oil passes through the hole of the filter, solid particles and viscous substances in the oil will accumulate in the filter. If the filter is blocked, when the oil cannot pass through the filter element,...
