Here are the specific reasons for gear shifting noise: 1. Damaged transmission housing: Long-term wear and deformation of the transmission housing and bearing seat holes. The noise is loudest when shifting into low gears and decreases progressively when shifting into higher gears, with the direct gear being the quietest. 2. Broken gear teeth: Due to broken teeth on certain gears, impact occurs during meshing. When shifting into that gear, strong impact and vibration occur, causing resonance in the transmission housing. 3. Improper transmission assembly: Incorrect replacement of gears, needle bearings, or bushings in a certain gear, or abnormal assembly clearance, leading to poor gear meshing and noise during transmission in that gear.

Where is the drainage hole of the Magotan car door?

Magotan car door drainage holes are located at the lower part of the door. Below is a detailed introduction about car drainage holes: 1. The drainage holes of Magotan car doors are located at the lower part of the door, and the two holes on the inner edge of the door outer panel are the drainage holes. During the use of the car, the owner should regularly check the drainage holes to ensure they are clear and avoid clogging. 2. According to their distribution locations, the drainage holes on a car can be divided into door drainage holes, sunroof drainage holes, air conditioning drainage holes, fuel filler drainage holes, and drainage holes at the lower part of the front windshield. 3. Door drainage holes: The car door glass is tightly connected with the sealing rubber strip, but more or less water will still flow into the door through the gap between the sealing strip and the glass during rain. These accumulated water inside the door will be discharged through the drainage holes at the lower part of the door.

What are the differences between BMW 330 and BMW 320?

The differences between BMW 330 and BMW 320 are as follows: 1. Different piston heads. 2. Different cylinder head bolts. 3. Different ECUs. 4. Different drive shafts. 5. Different half shafts. 6. Different rear axle differentials. 7. Different exhaust pipes. 8. Different wheel and tire sizes (same for iM models), with the 320 featuring 17-inch wheels and the 330 equipped with 18-inch 400M wheels, front 225/45R18 and rear 255/40R18. 9. The 320 is currently the lowest-priced imported 3 Series family sports sedan with a 0-100 km/h acceleration time of 7.6 seconds, available in Fashion and Sport Design Package versions, differing mainly in practical configurations. The 330 comes with M3 package components, is a standard 3 Series model with a 0-100 km/h acceleration time of 6.1 seconds, and the key differences lie in the M-grade package components, as well as the availability of a hybrid version in the 3 Series lineup.

What Causes Abnormal Idle Vibration When the Car Air Conditioner is On?

Here is a detailed analysis of the specific reasons for abnormal idle vibration when the car air conditioner is on: 1. Severe engine carbon buildup: The most common cause of vibration is a dirty throttle body or excessive carbon deposits in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts, making it difficult to start. The solution is to clean the fuel system and check if the idle control valve has carbon buildup, which should be cleaned. 2. Unstable fuel pressure: Check whether the fuel supply pressure and the intake pressure sensor are functioning properly. If the fuel pump supply pressure is abnormal or the intake pressure sensor values are incorrect or malfunctioning, it can cause body vibration. The solution is to check the fuel pressure and replace components if necessary. 3. Aging engine components: Car vibration is also related to worn engine mounts. Engine mounts are essentially the shock absorption system of the engine, responsible for absorbing minor vibrations during engine operation.

What are the precautions for idle cars?

During the period when a car is idle, the following precautions should be taken: First, pay attention to keeping the cab dry: because there are many metal parts and electrical appliances in the cab. If the cab is relatively humid, it is easy to corrode metal parts and damage electrical components. Second, pay attention to checking the battery: because most cars use lead-acid batteries, which will self-discharge even when the car is parked. Under normal conditions, the self-discharge of the battery can reduce the capacity by more than 1% per day and night. More seriously, after long-term self-discharge, sulfides will form on the surface of the battery plates, affecting the recharging effect of the battery, and may eventually lead to premature scrapping of the battery. Third, pay attention to the maintenance of engine oil and oil filter: it is necessary to replace the engine oil and filter element with new ones, because the old oil contains acids and moisture generated by combustion, which can erode the interior of the engine. After changing the oil, the engine needs to run for a period of time to circulate the new oil to all parts of the engine.
