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

-- Note the following when installing:

NOTE:

Clean out the hoses on the Differential Pressure Sensor -G505- with compressed air blow in the direction of the particulate filter in case they are blocked or iced over with condensation.

Check for secure fit and leaks.

If the particulate filter pressure lines were removed, tighten them to the tightening specification.

An adaptation must be performed after replacing the Differential Pressure Sensor -G505- and/or particulate filter. The procedures are also described in Guided Fault Finding.
