Question

Where is the boost compensator and what does it look like on a peugeot citroen XUD9TE 1.9TD engine with bosch pump?

Mine is in a Citroen Dispatch van so some stuff might be in different places to the cars.

Note: the intercooler is front mounted, unlike the cars.

The boost compensator unit can be recognised by a brass coloured diaphragm assembly connected to the intercooler by a vacuum hose.
