Dismounting and cleaning the air flow sensor and suction pipe
The air flow sensor normally does not need to be dismounted for servicing. Only clean it
when necessary (for a diagnosis see above: soiled pipe or sensor). The air flow sensor is
located in the combustion air suction pipe.
To dismount the sensor you need to remove various panels, depending on the model (see the
following pictures). Release the screws and remove the side panels and rear panel (after
disconnecting the mains socket!).
