A properly functioning ABS system is the foundation of road safety. Its main task is to prevent wheel lock-up during emergency braking, which allows the driver to maintain full control of the vehicle. The heart of this system is the electronic ABS pump controller. When it fails, the system stops working. A proper diagnosis of the problem allows you to avoid unnecessary costs and quickly restore brake efficiency.

Common throttle body faults
When the throttle body in a BMW starts to fail, the most common signs are:
- soot from the EGR system on the flap – sticking flap, fault codes stored in the engine control unit,
- failed motor or position sensor – engine warning light, limp mode,
- flap not closing fully – the engine may shake when switched off.
If cleaning does not help and diagnostics point to a throttle body or position sensor fault, replacement with a part carrying the same number is usually required. After fitting, many cars need an adaptation according to the vehicle manufacturer's procedure.
