Audi a4l new car idling body 3-4 seconds body intermittent jitter, 300,000 Audi hey? This shouldn't be there, uncomfortable! Idle, p, n gears all have body shake.
Some 4l shake, some do not shake, the circle of friends found a phenomenon is to run less shaky, running very basically did not find such intermittent slight shaking. Many people who shake have also solved, starting from the maintenance of the oil road, although the new car is very new, it does not mean that the fuel is completely new. This understanding, each car will have the initial fuel, for the plate car up and down to run to the store, in this process, the fuel is actually a long time, plus into the warehouse to sell out, a longer time, resulting in extreme deterioration of fuel, spoiled fuel will produce rapid pollution of fresh fuel, that is, there are oil bacteria in gasoline, the spread of bacteria is far faster than the bacteria in the place where there is sufficient oxygen, 2-3 days will fission the whole tank of fuel deterioration.
When all the fuel in the oil circuit deteriorates, and then through the combustion chamber combustion, the combustion quality is unstable, or the injection nozzle is extremely small aperture because the gum in these spoiled fuel exceeds the standard, and the impurities of large particles block the local position of the injector nozzle, and the intermittent injection atomization is not good, and the combustion jitter appears, so it is intermittent.
However, the fuel is not clean, therefore, the less the run the more serious the degree of pollution, the cycle will appear, more obvious jitter and carbon deposits exceeding the standard, vicious circle, tens of thousands of kilometers after the engine conditions are always at a high temperature critical value to work. The piston card ring has been stuck for a long time because of the long-term high temperature, and finally it is to burn the oil, and the injector nozzle of the direct injection car will not burn for a long time because it works in the combustion chamber, and the outside of the injector will produce excess ash continuous coverage, and the injector nozzle will appear after tens of thousands of kilometers of aging drip, resulting in a series of more uncomfortable driving experience and high fuel consumption, low power output.
The solution can be in accordance with the current method of many car friends in the circle of car friends, add additives such as general liquid in the fuel tank, run more, and when the bad substances are discharged through decomposition and combustion, the situation of idle jitter will be alleviated a lot to the end. Depending on the condition of the car, the new car is maintained 2-4 times. My car was idle jitter before intermittent slight shaking, 6000 km, after 3 times of maintenance, now 2w km red light still has no feeling of shaking.
Supplement, there is also a situation is the new car oil initial installation of oil quality or oil deterioration caused by the engine vibration is large, driven by the body idling shake, this situation can also be added in the oil has a general extreme pressure anti-wear agent, dozens of kilometers after the realization of super lubrication state, when the engine is working in the super lubrication state, the engine conditions can be improved, noise and vibration will be significantly reduced, the throttle will feel more relaxed, the vibration of the natural engine in the same speed situation is reduced, the shaking is not obvious.
