4.20.3 Cleaning fuel filter housing
Note
♦
The air mass value may be falsified due to excessive soiling
or moisture. This would lead to loss of power, since a smaller
injection quantity is calculated.
♦
Observe disposal regulations!
♦
The cleaning is carried out according to a separate calculation.
– Check air mass meter and intake hose for salt residue, dirt and
leaves (engine intake side).
– Check water drain hose in lower part of air filter housing for
dirt and clogging.
– Remove salt residues, dirt and leaves from upper and lower
part of air filter housing using a vacuum cleaner if necessary.
Note
When using compressed air to blow out the air filter housing, ob‐
serve the following: in order to avoid functional impairments,
cover the critical air-carrying engine components with a clean
cloth.
