BMW X3It is a popular one among consumersLuxuryMediumsuvBut before buying, we also need to understand its common failures, so that we can be more handy in the process of use.
Air conditioningUnable to refrigerate:BMW X3A common fault on the car model is:Air conditioningUnable to refrigerate:This may be due to the locationInstrument panelInternalEvaporation boxDamage caused by refrigerant leakage. To solve this problem, it needs to be replacedEvaporation boxHowever, due to the particularity of the installation location, the replacement process will be more cumbersome.
Brake padsAbnormal wear and tear: Another common fault is:Brake padsAbnormal wear and tear. BMW X3After 2-30,000 km, the gauge will appearBrake padsEarly warning, indicating that it needs to be replacedBrake pads。This is usually due to:Pump calipersCaused by incomplete return. It is recommended to do it firstPump calipersThe guide pins are lubricated, then observed for a period of time, and if the problem persists, a new brake needs to be replacedPump calipers
Engine idlingUneven combustion: Engine failure lights on, idle jitter, and weak acceleration are another common fault phenomenon. This may be due to uneven idle speed in combustion control. Repairs are made according to the content of the fault code, and if it is only a single fault and no parts are damaged, only the engine computer needs to be upgraded. But if there are others with the fuel exhaust system orCrankcaseVentilation-related faults** need to focus on checking the canister solenoid valve or exhaust valve.
Machine filterLeaking base and water pump: In addition,BMW X3It still existsMachine filterCommon faults such as leakage of the base and water pump. These failures are mainly caused by the aging of the rubber material, and it is recommended to check regularly and replace the parts in time to ensure the normal operation of the vehicle.
The above isBMW X3A brief analysis of common faults, although the failure rate is relatively low, it is still necessary to pay attention to it in the actual use process to ensure the safety and stability of the vehicle.
Audi Q5LIt is a medium-sized size that attracts much attentionLuxurysuvHowever, before enjoying the driving pleasure it brings, we also need to understand its common fault conditions.
All-wheel driveFaults:Audi Q5LOne of the common failures is:All-wheel driveFaults:When the meter appearsAll-wheel driveWhen a fault is indicated and the corresponding fault is stored**, it is most likely the rear axleDifferentialsCaused by severe wear and tear on the internal forks. To solve this problem, you only need to replace the fork orDifferentialsassembly.
2.Pedestrian protection device failure: Pedestrian protection device isAudi Q5Lbut also the possibility of failure. The fault manifests itself as a pedestrian protection failure indicated by the instrument, which may be caused by a loose plug of the canopy pop-up device. It only needs to be re-fixed in the harness or a little copper wire in the pins.
3.Abnormal noise on bumpy roads: Another common fault is abnormal noise when driving on bumpy roads. This could be a reinforced beam in the cabinboltsloosening. It only needs to be re-tightenedboltsto eliminate squeaky noises.
ReversingThe lights do not turn on: 2018-2019 modelsAudi Q5LSometimesReversingThe phenomenon that the lights do not turn on. This could be a lampholderContactsCaused by too large loose gaps. Just reprocess the lampholder and fix it againContactsCan.
5.Engine oil and water leaks:Audi Q5LThe engine often suffers from oil and water leakage failures. This is mainly due to the deterioration of the rubber material. Regular inspection and replacement of parts is the solution to this problem.
6.J949 emergency call module leakage: 2020 modelq5lSometimes there is a leakage fault of the J949 emergency call module. This can be caused by excessive electrostatic current. It only needs to be adjusted to fix the power supply.
In summary,Audi Q5LIn terms of failure rates withBMW X3Not much difference. Except for engine oil and water leaks, most of the other faults are relatively minor and relatively simple to solve. BMW X3withAudi Q5LAs two popular modelsLuxuryMediumsuvConsumers can refer to the fault situation when choosing, but also pay attention to the fact that individual failures do not represent the overall quality problems, and evaluate and compare all aspects to choose the model that suits them.
