BMW 5 Series: Solenoid valve injector
Measures at the solenoid valve injector
The following graphic illustrates the differences between the EURO 6b and
EURO 6c versions:

EURO 6 measures, solenoid valve injector
- Solenoid valve injector HDEV5 Bx8 engine, EURO 6b
- Solenoid valve injector HDEV5 EVO Bx8 engine, EURO 6c
- Solenoid valve injector HDEV6 Bx8TU engine, EURO 6c
- Injector seat
- Injection pattern and volumetric distribution
The Bx8TU engines use the HDEV6 solenoid valve injector by Bosch. Due to the
more stringent
exhaust gas emission regulations required to meet the EURO 6c exhaust emission
standards,
technical changes were again made to the solenoid valve injectors.
Due to the fuel system pressure increase from 200 bar to 350 bar, the solenoid
valve injectors HEDV6
were optimized using suitable materials and coatings. The injection pattern and
volumetric distribution
have not changed compared with the HDEV5 EVO.

The repair instructions that are currently valid must be carefully
followed when removing and
installing the injectors in Service. An excessive rotational angle at the
injector shank, and excessive
tensile and compressive forces during removal and installation can lead to
damage and therefore leaks
in the fuel system.

The vehicle can be accessed without operating
the vehicle key.
Carrying the vehicle key with you, e.g., in your
pants pocket, is sufficient.
The vehicle automatically detects the vehicle key
when it is in close proximity or in the car's interior.
