During maintenance work on the vehicles listed above, the question "Where are the service connections?" arises.
The service connections (high and low pressure) are at the front right of the engine compartment, between the air filter housing and the headlamp.
In order to access the connections, the air intake pipe (Figure 1) must first be removed.
The connections will then be accessible (Figure 2).
