1 SCR metering device
B128 SCR compressed air pressure sensor
B129 SCR AdBlue pressure sensor
We would like to point out that the SCR AdBlue pressure sensor (B129) and SCR air pressure sensor (B128) are now available again as separate parts from the GLC.
In future, if a defective pressure sensor is diagnosed on an SCR metering device, it must be replaced separately and the entire SCR metering device (1) may no longer be replaced.
The SCR AdBlue temperature sensor is not available as a separate part.
Please note the updated part numbers (see Parts Ordering Notes table).
The work instructions for the SCR air pressure sensors are already available in WIS. The relevant work instructions for the SCR AdBlue pressure sensors will be available as of WIS update 09/2009.
