1, the car oil table are not allowed

My car bought for some time, now there is a small problem, although not affect the use, but also made me very inconvenient. The problem lies in my oil table, its accuracy is absolutely doubtful. In the first 1/2 of the time, the pointer dropped very slowly, and after half of the feeling of the engine is like drinking oil in general, the pointer brush down down. Every time I will be in the pointer to reach the last white line when the refueling, but sometimes 100 pieces of oil added to the pointer to the location is not the same. And even once filled with oil, the pointer is not to the top, how is this going on?

Diagnosis and treatment advice: the rate of decline on the oil table pointer rate is not the same phenomenon, there may be design problems, some models of the oil table itself is not designed in accordance with the linear way, the first half slow, the second half of this phenomenon Should be more normal. Oil gauge pointer is unstable, oil level sensor may be a problem. If confirmed to fill the oil after the table did not watch the top, should be the oil meter monitor problems. These problems to the repair shop repair it.

2, car power windows suddenly automatically decline

My car is in the high-end models, four windows is the standard equipment, the original use is extremely convenient, especially the main driving side of a key lift design, eliminating the need to pay through some of the time, always hold down The trouble with the control buttons is much better than the electric doors and windows of my car. But there are various problems of high-level things, and now my main side of the power side of the window when the rise to the top, will suddenly drop a section, which makes every time I shut the window, but also carefully control it, save into a Trouble, will the control system is not a problem?

Medical advice: General limousine in the design of the power window will be installed on a anti-folder function, to avoid accidental operation caused by personal injury. In the course of the use of the vehicle, if the door top box with some objects, the window rose to this part of the time, the sensor will start anti-folder function, so that the window down. In addition, sometimes in the high-speed driving process, due to voltage causes the glass can not rise smoothly along the track, will also lead to anti-gripping function of the start. In this case, it is best to look at the special maintenance station to adjust, check whether there is a foreign body to affect the window movements, and to adjust.

Diagnosis and treatment advice: This will appear this situation, with your use or have a great relationship, according to the use of automatic transmission practices, L block is generally only in the rain, snow weather conditions, when the road adhesion is low, It will improve the engine to turn, gear driving, due to good road conditions, the speed will rise quickly, and this time because the limited speed transmission and will not shift operation, and thus the engine speed not only increased, resulting in huge heat, and These heat baked to the car's interior trim or ternary catalytic device, it will produce vague taste. Therefore, in the case of good road conditions, should avoid the use of L block cars, on the one hand is conducive to improving the speed and reduce fuel consumption, while the other people can make your car's engine, transmission from damage. ...
