As a garage, you may encounter Audi Q5, A6 or A8 Hybrid vehicles that display the P160900 Crash Shut-off error code. This annoying error can prevent the car from starting, and a warning light will appear on the dashboard indicating a problem with the hybrid system. Fortunately, with the right knowledge and tools, you can reset the Hybrid Battery Management System (BMS) and get the vehicle back on the road. In this blog, we will explain how to tackle this error.
What is the P160900 Crash Shut-off Error Code?
The P160900 Crash Shut-off error code is common in Audi hybrid vehicles. This error is usually caused by a sudden power loss or a crash, which causes the hybrid BMS to go into a protection mode. This system shuts down the hybrid drive as a safety measure, to prevent further damage to the battery or other components.
Typical symptoms of this error are:
- The vehicle will not start despite the dashboard lighting up and the engine attempting to start.
- A warning message on the display indicates a problem with the hybrid system.
- The vehicle may enter a 'limp mode', where performance and functionality are limited.
Diagnosing the P160900 Error
Before resetting the hybrid BMS, it is crucial to determine the cause of the P160900 error code. This can have several causes, such as:
- A defective hybrid battery or BMS
- Damage to high voltage cables or connectors
- Problems with the hybrid inverter or other components of the system
- A recent collision that activated the crash shut-off
At Car Key we use advanced diagnostic equipment to find the exact cause of the fault. This ensures that the BMS reset is performed correctly and that the problem is solved in the long term.
