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.

Symptoms of a worn or faulty throttle body
When the throttle body in a Mercedes starts to fail, the most common signs are:
- carbon deposits – rough idle, engine stalling,
- worn throttle position sensor – jerking, fluctuating revs, fault code stored in the engine control unit,
- in electronic throttle bodies: failed motor or gear drive – limp mode, loss of power, engine warning light.
When measurements or fault codes confirm the problem and cleaning has no effect, the throttle body is replaced with one carrying the same number. After replacement, many cars need an adaptation in the engine control unit.
