To repair the electronic steering gear failure in BMW 3 Series, it is necessary to use a computer to read the fault codes of the electronic steering gear. If the fault is identified as a steering gear failure, the steering gear should be directly replaced and reprogrammed. The following are the specific causes of electronic steering gear failures: 1. Excessive Air: A large amount of air in the power steering system can cause abnormal car steering. 2. Presence of Foreign Objects: Foreign objects in the steering hydraulic pipeline can cause the steering pump flow control valve to stick. 3. Loose Connections: Loose connections in the power steering system can lead to steering fluid leakage. 4. Piston Cylinder Wear: Excessive wear of the steering gear piston cylinder, poor sealing of the oil seal, or sticking/damage of the control valve.

Reasons Why an Automatic Car Doesn't Move in D Gear Without Accelerating

Here are the reasons why the car doesn't move in D gear and only moves when accelerating: 1. Throttle opening too small: It may be due to insufficient throttle opening of the engine or inadequate fuel injection from the injectors. 2. Transmission signal issues: It could be related to problems with the transmission control system or actuator signals, causing the shift valve to be unresponsive and failing to engage properly, thus preventing the oil passage from opening. 3. Principle: Normally, most automatic cars (especially older models without AUTOHOLD function) will slowly move forward at idle speed after starting the engine, pressing the brake, shifting to D gear, and releasing the brake (similar to manual transmission in 1st gear), but at a very low speed. The car will only accelerate when the throttle is pressed further.
