For the European and American car series "large oil consumption", running and dripping and other problems, because they have been engaged in car maintenance work, so the reason for experience is not strange, but the live broadcast room is often asked, but this kind of problem is not two words can be said clearly, fragmented short video is also more unable to break open and knead the presentation, simply write an article to talk about the views, for you to pay attention to the car friends to make a reference.
If this problem is not serious, there may be a considerable number of people who want to open their mouths and want to spray, and the network is rumored to be the oil consumption caused by the oil and gas separator problem, should this problem be solved? How to communicate and solve, if you can patiently read this article, I believe that the comments and suggestions in the article should be able to win the recognition of some people.
【Warranty and after-sales service】
At present, official information shows that BMW's models provide 3 years or 100,000 kilometers of vehicle warranty, the current store should also have extended warranty derivative projects, if you plan to choose the brand's models, it is strongly recommended to add extended warranty, in terms of the general trend, the future vehicle is not repaired, a repair is amazing, in advance to do a good job of protection, in case of emergency.
All car brands will boast the professionalism of after-sales service, to "manufacturer training, certified maintenance technicians and pure parts" to enhance the value of service, in order to tempt consumers to consume after-sales, but in the past two years to see some brands of after-sales service operations reflect the so-called professional, rigorous is really just talk, do not believe you look down, let's take BMW as an example.
【Oil passenger complaint data and analysis】
Inquired about the oil-related customer complaint data and quantity, I feel that the problem is not so serious, why do you have this feeling, let's continue.
Select bmw brand, keyword set "engine oil", retrieve relevant data, 2022 cases just full of 2 pages, that is, 60 cases, this data is obviously difficult to shake the relevant departments to investigate the project for this problem.
Although everyone has seen a lot of breaking news in the media such as forums and car friends circles, it seems that the problem is very serious, but these are not helpful to the troubled BMW owners.
Here is a knowledge point to share: BMW owners who are troubled by related problems can only start an investigation into some product quality problems until they complain to the relevant departments and accumulate a certain number of samples.
Take a look at the relevant cases for 2022 and list the models and models related to "oil consumption" as follows:
BMW 3 Series, 320, 325, 330, model year covering 2018-2021 models;
BMW 5 Series, 530, 525, model year covering 2020-2021 models;
BMW X3, 25, 28, 30, the model year covers 2020-2021 models, of which the number of BMW 3 Series cases accounts for a relatively higher proportion.
In 2021, the relevant data is less than 2 pages, about 56 cases, involving "oil consumption" related models and models as follows:
BMW X1, 25, specifically 2020;
BMW 3 Series, 316, 320, 325, 330, the annual model covers the 2016-2021 model, BMW 3 Series is still the main model, in addition to some BMW X5, BMW X6 involved in engine oil alarm.
I looked at some related cases, found a few cases of "there is a picture and the truth", described the incident relatively clearly, simply made a comment, but also for the riders to make a reference, how to effectively submit a complaint.
In the case above, not only the spark plug and the carbon deposition in the piston cylinder barrel are shown, the relevant narrative is quite clear, and it is simply done as follows:
Date of purchase: November 2020;
Vehicle mileage: vehicle 2 insurance, mileage of about 20,000 kilometers;
The cause of the problem was found: the spark plug had obvious traces of engine oil, and the carbon deposition in the cylinder was serious;
4S shop treatment scheme: add 5.75L of motor oil;
Customer comments and suggestions: asked to add 5.25L, but the 4S store asked to sign a disclaimer agreement, and finally added 5.75L of oil according to the 4S store.
In the above case, there is "transferred to... The State Administration for Market Regulation and Administration of defective product management center " related words, which is why the troubled car owners to make up the effective sample size, only if the sample size is sufficient, the relevant departments will start a defect investigation.
If the troubled car owners just casually pat and complain, these methods are basically not helpful to protect their legitimate rights and interests.
It should also be said that the case provided by this Guangdong rider is more valuable for reference, and it is simply decomposed as follows:
Vehicle maintenance interval: 11500 km, the owner found that the oil monitoring oil volume histogram shows only 2/5;
Case history: On February 23, 2022, the second insurance was carried out, requiring the measurement of the remaining oil amount (this is the right of the owner);
Test results: the remaining amount of old oil is 3.9L, and the owner calculates that driving 11500 kilometers consumes 1.35L of oil, and the average consumption of oil per 1000 kilometers is about 0.12L. 1/2 cylinder spark plug has oil stains, 3/4 cylinder spark plug is relatively clean, and the endoscope detects obvious carbon deposition in 1/2 cylinder;
Disposal plan: The owner recalls that the first insurance added 5.25L of oil, and this time the second insurance directly added 5.75L of oil, and the after-sales did not make any explanation, the rest of the problems we do not mention here.
The above case only shows the spark plug, of course, can also explain some of the situation, but if the cylinder carbon deposit situation is shown more convincing, the simple decomposition information is as follows:
Date of purchase: August 2021, the mileage is about 18,000 kilometers;
The problem was found: on March 14, 2022, the engine was inspected, and carbon deposits were found in all four cylinders;
Other problems: The owner mentioned that the maintenance manual recommends that the oil filling amount is 5.25L, but the 4S shop actually adds 5.75L according to the technical guidance of the factory. The owner believes that such an operation may cause damage to the engine and ternary catalysis, and the GPF may also be blocked, and it seems that the consumer still has a certain understanding of the risks of related problems.
In the case above, we can see that the reply did not turn to the relevant department, so the author believes that the case is not convincing, it is recommended to accompany the picture, after all, there is a picture with the truth, and the relevant information is simply decomposed as follows:
Date of purchase: February 2021;
The problem was found: in August, the first guarantee added 5.25L of engine oil, after driving 10,000 kilometers, the oil alarm was alarmed, the remaining oil amount was confirmed to be 3.7L, the calculation reduction amount was 1.55L, and the engine 1/2 cylinder spark plug had obvious oil stains and carbon deposits;
Owner's opinion and request: replacement of valve room cover;
4S shop reply: ask to add 5.75L oil, travel 3000-10000 kilometers test, to check whether to burn oil.
Owner's Concern: What is the standard value of oil consumption? How is burned oil measured?
【Comments on related cases and disposal plans】
Let's first take a look at the instruction manual of a German car about 20 years ago, "the engine oil consumption is up to 1.5L/1000km", hahahahahaha
So the vehicle quality problem is very easy to rip off, may encounter back and forth kicking the ball, so the author has been advocating "choose a car homework to do well, with the car to raise a car no trouble", before the choice we are all Gods, choose at least can be a Sven customer, if the choice is not good to go to the rights protection of the time may be the brand side in the system to do "special labeling", so how to choose the car in the end? Do you hear people blowing about how well this car behaves in driving and riding? How rich is the configuration? How clever the elk test scores are... Just pay for it?
For the dynamic performance of a car, we must take our own personal experience as the standard, to put it bluntly, the vehicle dynamic test is to see others cool, when a lively look does not matter, but their own heart to follow the dark cool, then you must be careful, timely press the sensibility, must be all-round understanding of the vehicle.
This is also why I am more willing to share some after-sales cases with you every day, even if I drive the Joy of Pegasus, if this Pegasus is not good at work, we are not worried about it.
We then said BMW oil consumption, if most of the cases are feedback 1/2 cylinder serious, and 3/4 cylinder is basically no problem, then confirm the crankcase forced ventilation into the intake manifold is not next to the 1/2 cylinder closer to basically determine whether it is the crankcase forced ventilation system problem.
Look at the oil consumption, if we catch up, the vehicle travels 10,000 kilometers to consume about 1.5L of oil, it is recommended not to directly add to the 5.75L oil, you can travel every 3000-5000 kilometers, add oil to the standard position, so that the vehicle is better.
Previous experience, the oil added more engine internal resistance, vibration, acceleration stuffiness, will further aggravate the oil consumption, produce more carbon deposits, and may even induce piston rings, crankcase air channeling volume further increased, eventually leading to real burning of oil, not to mention the impact on ternary catalysis, exhaust emissions, particle traps.
Adding 5.75L oil is a solution that is first of all the brand's self-denial in terms of professionalism and rigor.
The oil level does have a certain degree of tolerance, but the general organic oil scale model, the upper and lower limits of the liquid level is the so-called tolerance, in general, many repairmen are willing to add oil to the upper limit, so we can understand that the 5.25L that the official has given should be the upper limit of the oil level.
In order to avoid the oil level alarm, add more 0.5L oil, this disposal scheme is very unprofessional, even better than shortening the maintenance mileage to 7500L kilometers, in the long run, although the owner of the maintenance cost increased, but it is possible to reduce the future because of the amount of oil refueling too much to produce "carbon card ring leading to real burning oil, oil consumption further increased, power deterioration, three-way catalysis and particle trap and other problems" and have to carry out the risk of maintenance, BMW overhaul an engine is more expensive, How expensive it is to replace the relevant parts is, there must be a BMW owner who knows.
【Advice for car owners who are plagued by large oil consumption】
1, first of all, we must insist on adding 5.25L oil according to the standard, check the oil level per 3000-5000 kilometers, add it if necessary, or shorten the maintenance cycle to about 7000 kilometers (now there are still some models every 5000 kilometers boayang once, people are not the same);
2. If there is a problem of large oil consumption, we must file a valid complaint and make more sample sizes to prompt the relevant departments to file a defect investigation, rather than complaining wherever they are, which is worthless;
3. Consideration may be given to jointly raising a joint lawsuit with a crowdfunding lawyer to safeguard rights in accordance with law;
4. Detecting exhaust emissions, if the exhaust emissions exceed the standard, complain to the local environmental protection bureau about the relevant brands, this experience comes from a paper "Administrative Penalty Decision Letter" issued in January 2016, the specific information is as follows:
If the vehicle does have a large amount of oil consumption, exhaust emissions may be affected, if the detection of exhaust emissions is unqualified, the sample volume may be enough for the brand to drink a pot, environmental protection is more stringent, which is called the sword to take the side, forcing the brand to pay attention to the legitimate rights and interests of consumers.
If the detection of exhaust emissions is qualified, then this problem does not have to worry too much, nothing more than a trouble point, more than two times of maintenance, maintenance costs are high, the future will not affect the on-line inspection of the car.
If you now use more oil to prevent the disposal plan of the oil alarm, in case the future affects the ternary catalysis, particle capture device, then need to go online to inspect the car, the result is not up to standard, then the vehicle may have been insured, maintenance costs will inevitably be expensive.
5, both come to peace, encountered such problems, the current analysis should not be serious, do not affect their emotions and health because of such problems, according to the law to protect their rights, all roads through Rome.
Finally, it is still recommended that when car consumers choose a car, they should still fully understand the problem of car maintenance with vehicles, and understand in advance that even if they encounter a car when they use a car, it may not particularly affect their mood, what to do.
