Is the MG engine easy to repair?

By the 7th of next month, MG7 will have been working for four years, and I still remember mentioning MG7 for the first time. Because there was something wrong when I picked up the car, 4S gave me four maintenance, and once I wrote an article for myself and maintained it five times. Because I don't drive many miles and run in the main city, I basically have free maintenance during the warranty period (courtesy of Lexus).

Last year, I bailed myself out. Let's talk about the maintenance and some problems of MG7 during the warranty period. Use 4S engine oil for 0-2 km. At that time, the merger between Shangnan and South-South was not deep, so Castrol mineral oil was used. After driving 20 thousand kilometers, 4S maintenance began. I made up the difference myself. I also made some minor improvements to MG7, adding a rear anti-roll bar to the body structure, and replacing the low beam with Philips Silver Warrior. Within 30,000 kilometers, the maintenance of MG7 actually didn't cost me much.

Speaking of the problems in the warranty, the biggest problem should be that the oil meter is inaccurate, sometimes it drops quickly, sometimes it doesn't move or even rises. Two oil pumps have been replaced successively, and there is still no substantive solution. It seems to be a common problem that MG7 oil meter is inaccurate. The main hidden danger is that it will be thrown into the road because there is no oil on the road, but as long as the estimation is accurate, the problem will not be great. Now it's basically a quarter of an hour to refuel, which is basically no problem.

The engine fault light came on twice, and the main problem was the ignition coil. Claim one. Later, similar problems appeared after bail. I changed the ignition cylinder line. In addition, the claim is for oil leakage from the rear shock absorber. I guess it was caused by building roads everywhere in the early stage of Shanghai World Expo. I drive very hard.

High voltage ignition circuit change

Generally speaking, the quality of MG7 is acceptable within the warranty period, and there is nothing wrong with it. This should be related to the fact that MG7 is a mature car.

After the warranty period, we began to make some minor changes to MG7. In fact, nothing has changed, except Bosch Ruineng Class IV and high-voltage ignition wire. I really don't feel the influence of power, but when I turn on MG6 manually, I obviously feel that the speed of MG7 is sharper. I don't know if I changed those relationships, or if MG7 is a mechanical throttle (old model) and MG6 is an electronic throttle.

Besides changing the tires, I also changed the brake pads. At first, I was really a little fierce. More than 30 thousand kilometers of brake discs are almost worn out, so I use the so-called imported wear resistance. It seems that the effect is not much different from the original, but the marking of the rear brake pad is suitable for BMW7 series, which caught my attention. It seems that some parts of our MG7 and BMW are really ordinary. Thirty-five thousand kilometers of bail pending trial, plus Jin Mobil for minor maintenance. It feels good.

Four-wheel alignment when changing tires

Last week, I did a major maintenance of 40,000 kilometers (the oil will deteriorate after a long time, so I did 6000, actually according to Jin Meifu's 7500. ) The main items include oil filter, throttle cleaning, engine cleaning, oil filter replacement and brake oil replacement. In addition, antifreeze and engine belt were checked. I bought spare parts myself, and my working hours are in 80 yuan. Less than 1000. If you put it in 4S, it will cost at least more than 2000 pounds. After all, it costs thousands of pounds to replace a golden Mobil car. As for the maintenance details, I still have to mention that the 4S is 4.5 liters and the garage outside is 5 liters. I don't know which is more accurate. 4S always takes the remaining half liter, and who knows what it will be used for.

At present, most MG7 products are shipped from 08- 10, and many of them have already been guaranteed or are ready to be opened. If possible, you can buy your own parts and find a safe garage to repair them, which will save money and use better things. As for where to buy these spare parts, my channel is online. General spare parts such as engine oil and brake oil. They are sold in JD.COM and Zhuoyue, so the probability of counterfeit goods is relatively small. It seems that there are machine filters and air filters selling MG7 in JD.COM recently. Might as well buy a few spare ones, which are not expensive. Just like an empty filter, you can change it yourself. There are also some mg7 specially for Taobao. As for which seller must be chosen. After all, there are too many common accessories for MG7, Roewe 750 and MG6, and these accessories are easy to find.

I estimate that this car will last for another three to four years. As for what car to change at that time, it mainly depends on the budget at that time. Of course, the new MG7 should also come out by then, which should also be one of the potential targets.
