What s the deal with the BMW 118i steering wheel so heavy

1. The steering power oil is too dirty. The booster oil is the force transmission medium, if the oil is too dirty, it will cause poor circulation and difficulty in the general direction. The more serious steering power pump will also "buzz".

2. Lack of booster oil or oil leakage. If the booster oil is gone, it is equivalent to no help, check whether there are traces of oil leakage in the relevant system. Focus on inspecting the steering power oil pot, power oil pipe, and steering machine.

3. The engine booster belt is too loose or too tight, or the belt is aging, the tightness can be adjusted, and the belt can only be replaced when it is aging. 4. The bearing of the steering system is too tightly matched or the lubrication is poor; The ball joint of the steering tie rod is adjusted too tightly or there is a lack of oil; Friction caused by bending of the steering shaft and casing is a mechanical fault of the steering system. Some cars can adjust the mating clearance, but most of them can't; The steering tie rod ball joint is generally recommended to be replaced; The steering shaft and casing are bent unless there is a major accident or man-made, and it is rarely possible to damage.

5. The front axle or frame is bent and deformed, and some can be adjusted through sheet metal, and most of the time it is recommended to replace it.

6. The front wheel toe is too tight, and four wheel alignment needs to be done.

7. Insufficient tire pressure, in fact, this should be the first to be checked, and it is also the easiest to judge, but it needs to be used with the help of a barometer, but this change is not obvious and cannot be observed with the help of the naked eye.

The steering wheel can be lightened.

Bmw. The steering wheel weight can adjust the rack adjustment screw of the steering machine and change the engagement clearance. Start the engine. Hit the steering wheel to the left and then use the 17 wrench.

Drain the oil and then screw it out. Hit the steering wheel to the right, then use the 17 wrench to drain the oil and then screw it to death, back and forth three or four times. If it is not assisted, adjust the steering machine adjustment pad.

BMW 118 parameter configuration.

Three-cylinder, configuration, high-speed movement, dynamic traction.

The control mode raises the intervention threshold of the Dynamic Stability Control system, allowing for slight slippage of the drive wheels, which facilitates controlled oversteer.

In dynamic stability control shutdown mode (DSCOFF), electronic rear axle differential.

Lock the system to start. When accelerating through a tight corner, if one of the drive wheels slips, braking force is applied to that drive wheel separately, allowing the opposite side of the wheel to maintain traction.

The pleasure of driving in the limb is so real that at least at that moment my dream came to life, and you can choose between Comfort, Sport, Eco-Pro and Sport modes specific to the BMW WW118i Sport. They give you different steering feel and sensitivity to the power output.

Steering wheel. The reasons for the sinking are: 1. Insufficient booster oil, 2. Tire pressure.

If it is too low, the nuclear potato 3, the bearing fit is too tight, and the 4. booster problem can be dealt with according to the actual situation.

1. Insufficient booster oil.

Generally, the feeling of the weight of the direction is relatively constant, if it suddenly becomes very heavy one day, or slowly becomes heavier, it may be that the steering power oil is dirty, it is similar to the engine oil, and it needs to be replaced. Or if there is less oil leakage, then there is less power, so the steering wheel becomes very heavy. In this case, it is necessary to maintain it in time, or to add and change the steering oil.

2. The tire pressure is too low.

If the tire pressure is too low, the area of contact between the tire and the road surface will increase, the friction will increase, and the steering difficulty will increase, resulting in a heavy steering wheel, which is not conducive to driving safety.

3. The bearing fit is too tight.

For each rotation of the Lee's shirt is connected to the system with a rolling bearing.

In this case, the mechanical part and the booster system should be checked, or whether the cavity has leaked oil inlet seal damage phenomenon.

4. Booster problem.

The relationship between the steering wheel and the booster is inseparable, so when the steering wheel becomes very heavy, it is likely that there are some poor circuit contacts or other problems inside the booster system, which should be repaired by the 4th shop.

The steering wheel of the car shakes, this situation is very common, some car owners can feel a strong steering wheel shake when driving the car at high speeds, when the speed reaches 80-100km h or more. In this case, most of the problems occur in the tires of the car, because the uneven distribution of the mass of the whole part of the tire will cause the wheels to rotate at high speed, and there will be a dynamic imbalance state, which will cause the steering wheel of the car to shake seriously while driving. In this case, it is necessary to align and dynamically balance the tires of the car, and in serious cases, the tires must be replaced.

In addition to the tires of the car, there may also be shock absorber failure, frame deformation, excessive meshing clearance of the main and driven gears of the final reducer, etc. If the steering wheel shakes when braking while driving, then it is very likely that the brake force is too strong and too frequent, which may cause the brake disc and brake pads to overheat and deform when cold, causing the steering wheel to shake.

Generally, the symptoms can be solved after replacing the brake discs and brake pads. If the speed of the vehicle is not fast, but the steering wheel shakes, it is possible that the steering belt of the mechanical steering system will slip when the belt is too loose, which will also cause the steering wheel to shake, and there will be shaking and abnormal noise when the steering transmission system is loose and the gap is too large, but this situation is rare.

In most cases, the failure of the multi-function steering wheel button is caused by the poor working performance of the spiral cable at the lower part of the steering wheel or the problem of false connection. Hope mine can help you.

How to shake, brake shake, or run up and shake,

First, the cause of the failure of the knuckle arm deformation. Steering knuckle thrust bearings are missing or damaged. The gap between the kingpin and the bushing of the steering knuckle is too small or there is a lack of oil.

Deformation of the front axle or frame causes the front wheel to misalign the front wheels. Insufficient tire pressure. The steering gear bearing assembly is too tight.

The meshing clearance of the transmission pair is too small. The ball pin of the transverse tie rod is too tightly assembled or the joint is short of oil. The steering shafts or main pipes bend, rub, or get stuck against each other.

Pay attention to improper lubrication of the steering companion device and improper toe-in adjustment. 2. Fault diagnosis and elimination Support the front axle and turn the steering wheel. If the steering feels nimble, the fault is with the front axle and wheels.

This is because when the front axle is supported, the contact resistance between the wheels and the road surface is no longer present when the steering wheel is turned. At this time, carefully check whether the front wheel pressure is too low, whether the front leaf spring is intact, and whether the frame is deformed. Support the front axle and turn the steering wheel.

If you feel heavy steering, the fault is with the steering gear or steering drive. At this point, the steering arm can be removed and the steering wheel can be turned. If it feels heavy, it means that it is an internal fault of the steering gear, and the damaged parts should be repaired or replaced as needed.

After removing the steering arm, turn the steering wheel. If it feels light and flexible, it means that the steering gear slag is fault-free. After checking with the above methods, if the tires, front leaf springs, frame, and steering gear are not faulty, it can be basically determined.

Millions of car purchase subsidies.

The steering wheel is too heavy because of insufficient booster oil, low tire pressure, over-tight bearing fit, power assist problems, etc.

Insufficient booster oil:

In general, the sense of weight in the direction of hitting the ball is relatively constant. If it gets heavier suddenly, or slowly. It may be that the steering oil is dirty, and it needs to be replaced about the same as the engine oil.

Failure to do so may result in an oil leak that will cause the steering wheel to sink. This condition requires timely maintenance, or adding and replacing steering oil.

Tires Low pressure:

If the tire pressure is too low, the contact area between the tire and the road surface increases, the friction increases, the steering difficulty increases, and the steering wheel is heavy, which is not conducive to driving safety. In this case, the air pressure should be replenished in time.

Tight fit of bearings:

Every steering system is connected to rolling bearings and fits closely with sliding bearings, so the sail will lead to poor lubrication of the bearings, jamming, and sinking of the steering wheel. In this case, we should inspect the mechanical components and the power system, or rule out the seal of the oil leak inlet for damage.

Booster Questions:

It is closely related to the steering wheel booster, so when the steering wheel becomes heavy, it is likely that the power assist system has poor circuit contact or other problems, and it should be inspected and repaired at 4 shops.

Summary. Hello dear, the following answers have been made to your questions, yes, I helped you sort it out!

The steering wheel of the BMW 3 Series is getting heavier and heavier: in fact, the handling of BMW cars is notoriously "stable and accurate". In other words, the steering wheel of a BMW car is relatively heavy.

The purpose is also obvious, and the steering is precise. However, it is not as excessive as most people say. The handling of the BMW car is mainly due to the feedback from the road surface.

So, it is a tradition for the steering wheel of a BMW car to sink. In addition to this tradition, if it feels like the steering wheel is getting heavier than it was when it was a new car, then you have to consider whether there is something wrong with the car.

Why is the steering wheel of the BMW 13 so heavy.

The handling of the BMW car is mainly feedback from the road blind waiter, and the potato god bend is obvious. So, it is a tradition for the steering wheel of a BMW car to sink. In addition to this tradition, if it feels like the steering wheel is getting heavier than it was when it was a new car, then you have to consider whether there is something wrong with the car.

Count the stuffiness. The reason why the BMW 3 Series steering wheel is getting heavier and heavier: the first thing to consider when returning to the reserve is that the steering power assist oil is dirty; or the problem caused by the leakage of steering power oil and the reduction of oil; The coordination of each axis between the axes is too tight, the lifting of the ball head of the steering tie rod is too tight, and the stagnation caused by the bending of the steering shaft and the casing. Whether the tire is losing air, the contact area and friction between the tire and the ground increase after the tire is deflated, which will also cause the steering wheel to become heavier. When the car appears in the above situations, don't panic, check it yourself first to see the reason, if not, it is recommended to find a professional repair shop to check and repair it.
