Removing The Injector Valve (Injector)

WARNING: This page is about a different variant/trim than selected.

WARNING: Highly inflammable or explosive materials

Danger of fire or explosion
→ Avoid contact with hot parts or sources of ignition.

→ Use suction to remove ignitable vapors.

→ Attach warning sign in a clearly visible position.

→ Contain leaked media using non-flammable absorbent material and put it in a container designed for this purpose for disposal in accordance with local requirements.

→ Secure collection containers/vessels to prevent them from tipping over.

NOTE: Dirt on injection system components

Material damage
Rough-running engine
Bad exhaust emissions
→ Thoroughly clean connection points and adjacent areas before loosening them. If the engine is very dirty, wash it before starting disassembly work.

→ Lay removed parts on a clean surface and cover them. Do not use fibre-shedding cloths.

→ Carefully cover components or seal them if repair work will not be carried out immediately. Place rubber caps on connections. Seal intake openings with film or adhesive tape.

→ Only install clean parts. Do not take spare parts out of the packaging until just before installation.

→ Never use compressed air when the system is open. Do not move the vehicle.
