97+15 is not a fault code, it indicates the exhaust brake valve is open and can be manually closed. Here are specific details about the exhaust brake valve: 1. Introduction: The exhaust brake valve is an auxiliary brake and a necessary supplement to the vehicle's service brake. It uses the engine as an air compressor to generate braking torque, thereby slowing the vehicle down. 2. Application: Generally installed in the exhaust pipe, it closes the valve when deceleration is needed to block the exhaust channel and achieve braking effect. It is mainly used in vehicles that operate in mining or mountainous areas or frequently drive in complex urban traffic conditions.

What Causes the Abnormal Noise When MG ZS Drives on Uneven Roads?

The causes of abnormal noise when MG ZS drives on uneven roads include shock absorber failure and top mount bushing failure. Shock Absorber Failure: The solution is to replace the shock absorber with a new one. The shock absorber is a wearable part on the car and can last for a long time. However, after prolonged use, the shock absorber may start leaking oil and needs to be replaced in time. Top Mount Bushing Failure: The solution is to replace the aged buffer bushing with a new one. The connection between the car's shock absorber and the body has a buffer bushing, which is a rubber component. Rubber components harden and age over time, causing abnormal noises when the car drives on bumpy roads.

Why is the noise so loud after turning on the air conditioning in the new Santana?

The loudest noise heard after turning on the air conditioning is the sound of the electric fan running at high speed. Increased engine load: Because the compressor starts working, the engine load increases, and the speed must be increased to supplement power. Otherwise, there will be poor operation and unstable idle speed. So when listening outside the car, in addition to the sound of the electric fan, the engine speed is high, and the noise will also be louder. However, it is not so obvious, and the noise will be covered by the electric fan. The noise of the electric fan is really too loud. The electric fan has two gears: The electric fan operates to dissipate heat for the radiator and condenser. There are two gears, low speed and high speed. If the air conditioning is not turned on, the rotation only dissipates heat for the radiator. It does not turn on when the water temperature is low, and only turns on when the water temperature is high. In most cases, starting the low-speed gear can provide good heat dissipation without the need to turn on the high-speed gear. The noise of the low-speed gear is very small and not obvious to hear.

What is the difference between BMW X1 with and without Huachen?

BMW X1 with and without Huachen has the following differences: Exterior differences: In terms of appearance, the domestically produced Huachen BMW X1 has hardly changed much compared to the imported version.

The only difference is the addition of the "Huachen BMW" logo on the rear of the car to indicate its different identity. Interior differences: The interior design is no different from the imported version. The center console is slightly tilted toward the driver's side, the iDrive system remains clearly visible, and the rear seat backrest angle can be adjusted in multiple stages, with a maximum of 31°. When the backrest is in the vertical position, the trunk capacity can be increased from 420 liters to 490 liters.

However, the domestically produced BMW X1 sDrive20i rear-wheel-drive version and X1 xDrive20i four-wheel-drive version, equipped with a low-power 2.0T engine, have replaced the imported BMW X1 xDrive25i four-wheel-drive version, which was equipped with a 3.0 naturally aspirated engine.
