Finally, a summary.

It’s really nice to see 30,000 kilometers from the company, take a picture and save it right away.

Do your homework before maintenance

The old rule is to think about what you need to maintain before going to the 4S store and try to avoid unnecessary waste. Refer to the maintenance project of Automobile House, and according to your own actual situation: last time, Erbao changed the engine filter + air filter + air-conditioning filter (if you are interested, you can read the previous post). It means that the spark plugs were not replaced as recommended last time, and the main individuals do not think it is necessary to replace them so early. The replacement of spark plugs is the most controversial in this generation of G38 BMW 5-series maintenance, so when is the right time to replace spark plugs? Don’t worry, listen to me slowly!

Here or put a car home maintenance project as a reference!

Q. how long will it take for the G38 BMW 5-Series to replace the spark plug?
A. BMW’s original car was a champion spark plug (some of which were NGK in 17528), and BMW officially recommended a replacement of 20,000km.
Q. is there anything to change if it is not 20, 000 kilometers? Does it have a big impact on the engine?
A. the worst-case scenario is that the internal combustion of the G38 generation 5-series engine is relatively high, and if the small contact on the spark plug head falls off into the cylinder, it may cause the cylinder to pull. However, it does not rule out the possibility that this will not happen after the replacement of new spark plugs. And the probability that happens is like you won the lottery.
Q. how did I do it?
A. based on my own experience and feedback from other riders in the forum (20,000 km replacement looks relatively new and a bit wasteful), I originally planned to replace 40,000 km, but I replaced 30,000 km in advance for the first time.
In fact, during the maintenance of the 4S store, I asked us the cycle of repairing spark plugs and gasoline filters, and my reply was quite sincere, which was basically similar to what I considered: the spark plugs they suggested was 30,000 kilometers, and the conservative point was 30,000. the gasoline filter element can be replaced at 40,000 kilometers. I would like to thank our maintenance brother here!
To put it bluntly: the boss who is rich and wayward can be replaced directly without any worries or doubts. Those who are industrious and frugal can judge themselves according to the analysis.

After-sales reception maintenance

According to the plan in advance, maintain oil, filter and replace spark plugs. I bought the car when the maintenance is free, and then change 4 spark plug materials + man-hours a total of 905 yuan. No photos, basically the same as the previous steps of the second guarantee.

Go directly to the maintenance workshop and observe the craftsmanship of the maintenance craftsmen

I don’t have a mosaic anyway. If you see it, you can drop it.

Repair the maintenance accessories brought by the younger brother

They are: 6 bottles of 1 liter oil + oil filter element + 4 spark plugs (BMW B48 series maintenance oil 5.25 liters or so 4.8 liters, so 6 bottles)

4S stores routinely use oil Longglife-01 5W-30 (after sale, you will also be recommended to add a few hundred yuan to use better oil).
Here is a key point of popular science: even if you buy a car for free maintenance, you can also ask for this small bottle of engine oil after sale!

The new NGK spark plug must be much better than the champion spark plug of the original car.

After a while, the maintenance brother has already begun to remove the spark plug. Before removing the spark plug, you need to remove the cylinder separation line (ignition coil), and then use the special wrench to remove the spark plug.

The four old spark plugs removed seem to be wound very well, and such a color change can be regarded as OK.

Comparison of new and old spark plugs

In fact, the spark plug mainly depends on the contact and the gap. Basically, it’s almost done, and the rest will be left to the maintenance brother.

It’s almost time for dinner, how can you leave without having a meal?

Baohua’s food is all right. Look at so many people (mainly little sister).

It is a little different from what I have eaten before. I used to cook by myself and make whatever I want; now the two dishes are different, so I can make my own choice.

It is the international practice to take a look at the pre-sale showroom. Many people just look at the pre-sale and then change cars.

I like the standard axis, but reality is more important. There is no more emotion here!

95% of people who buy 5-series should still choose the long axis. After all, 5-series have to take care of housework and business.

The headlights and rear lights of the 2021 model are still very good, and of course our older generation is not bad either.

After the maintenance of the 4S store will wash the car, and then contact you by phone: handsome, the car maintenance is ready!

Finally, a summary.

The maintenance originally done a year ago has been delayed for a month to hand in homework, and I have really become lazy. I’m so free today, so hurry up and do it!
I write down every maintenance, why do I keep doing this all the time? First of all, there are always car stickers in the forum, and I feel that I need something new and different to discuss. Some people don’t know how to ask, and I know a little bit about my own car claims, so I don’t have to reply by hand every time and just throw a link at that time.

Finally, we have a “Suzhou BMW 5 Series WeChat Group” if you need to enter, please contact me (Wechat search: *, note: car Home), there are also a lot of little sisters in it! Irregular gathering activities in the group, mainly chatting and making friends, of course, there is business? The mutual help and the exchange of resources are better.

There are two articles below, my car pick-up sticker and the second guarantee sticker, if you are interested, you can also read it!

20 years old and 3650 days, give yourself a big toy 525Li M national six.
