Calibrate BMW Steering Angle Sensor
In this guide, you will learn how to calibrate the BMW steering angle sensor.
A BMW may show warning lights on the instrument cluster when warmed up and could even go in fail-safe mode. The warning lights may come up intermittently. The vehicle returns to regular operation after the car is restarted or cooled down.
In this guide, you will learn about common issues that can cause intermittent BMW problems.
Typically allowing the car to cool down, restarting it, or clearing the codes, will enable the vehicle to run normally.
A BMW can get stuck in gear intermittently when the transmission fluid is low or the on-board voltage drops while the engine is running. If you have a BMW that loses power, gets stuck in gear (fail-safe mode), the first thing you need to do is to check the transmsion fluid level and ensure you have a good battery that holds a reasonable charge.
If the transmission fluid level is correct, the next troubleshooting step is to read the fault codes from all modules.
Any of these modules could have an internal fault. A defective connector or damaged wire harness can also be the problem.
The problem can be due to a fault in the CAN-BUS network issue. The typical modules that run on the CAN-BUS II are the gear selector, engine control unit, and transmission control module.
The next step is to read the codes from all the modules listed above.
The next step in diagnosing BMW intermittent issues is to read the fault codes from all the modules and determine the next steps. To read fault codes from all the modules, you will need a specifically designed scanner for BMW.
After reading the code, you should have a better idea of what to focus on next.
A BMW with the following fault codes may have a bad engine control unit, shifter module, or transmission control module. The most likely cause is a faulty transmission control module, which in most BMWs is installed inside the transmission on the valve body.
DME / DDE Engine Codes
EGS Transmission Codes
It is important to note that BMW's irregular fault codes can be very challenging to diagnose. We do not recommend replacing any of the parts or components listed here without first performing a diagnostic.
