5.

Fit cable connector on injector.

Reset CDC parameters after installing new injectors

Note:

If the drift correction (CDC) is not reset, the emission certification becomes invalid.

u

Reset drift compensation (CDC) using DiaSys® and enter injector code (IIG) (→ Dialog system DiaSys®
E531920/..). If DiaSys® is not available, contact Service.

Final steps

1.

Install cylinder head cover (→ Page 130).

2.

Open fuel supply to engine.
