1 Answers
The causes of the abnormal noise in Song Pro may be due to abnormal front wheels, loose chassis fasteners, or abnormal engine accessories. Confirming the existence of the fault: During a test drive with the customer on a flat road, a clear metallic "clicking" sound could be heard inside the car when slightly pressing the accelerator pedal, confirming the existence of the fault. Checking engine accessories: After lifting the vehicle with a lift, inspections of the front wheel brake discs, dust covers, all bolts and ball joints in the chassis showed no abnormalities. When checking the engine accessories, it was found that the air conditioning high-pressure pipe was loose when shaken by hand. Further inspection revealed that the bolt securing the air conditioning high-pressure pipe was loose. After tightening the bolt, the abnormal noise disappeared during the test drive.
