Question 1

How to remove and install the Air Filter Box on Volkswagen Jetta?

Accepted Answer

For 1.4L engines, loosen the clamps securing the air intake duct(s) to the air filter housing and detach the intake duct(s), disconnecting any air hoses and the breather hose. If applicable, detach the crankcase breather hose. On DGXA engines, disconnect the electrical connector from the Mass Air Flow (MAF) sensor. Firmly pull the air filter housing upwards to detach the rubber grommets, then rotate the housing forward on DGXA engines to disconnect from the duct before removing it from the vehicle, with installation being the reverse of removal. For 1.8L and 2.0L turbocharged engines, on Jetta models, release the air guide top cover clips and remove the top cover, then release the lower clips and remove the guide with the air duct hose. Loosen the clamps securing the air intake duct to the air filter housing and throttle body, then detach the intake duct. Disconnect the air injection hose if equipped, and the vacuum line from the air filter housing lid. On Golf models, pull the air filter housing upwards to detach the rubber grommets, rotate the housing upwards at the rear to disconnect from the duct, and remove the bolt at the rear on Jetta models before removing the air filter housing from the vehicle, with installation being the reverse of removal. For 2.0L non-turbocharged (CBPA) engines, available only in Jetta models, loosen the clamp securing the air intake duct to the air filter housing and detach the duct. Pull the air filter housing upwards to detach the rubber grommets, lift the housing and disconnect it from the intake air duct at the bottom. To remove the air guide, release the top cover clips and remove the top cover, then release the lower clips and remove the guide from the air duct hose. Remove the left front inner fender liner to access the lower housing assembly, remove the bolt attaching the guide air intake duct to the bracket, loosen the clamp securing the air intake duct to the lower housing, detach the duct, and remove the fasteners securing the lower housing to the vehicle before carefully removing it, with installation being the reverse of removal. For 2.0L turbocharged (CBFA and CCTA) engines, on Jetta models, release the air guide top cover clips and remove the top cover, then release the lower clips and remove the guide with the air duct hose. Disconnect the electrical connector from the MAF sensor, loosen the clamps securing the air intake duct to the air filter housing, and detach the intake duct from the MAF sensor. On CBFA engines, disconnect the air injection hose from the air filter housing cover, remove the air filter housing cover fasteners and cover without completely removing the fasteners, then remove the air filter housing mounting fastener, lift the housing up, and disconnect it from the intake air duct at the bottom. Inspect the condition of the water drain and hose while the housing is out, and thoroughly blow out all parts of the housing with compressed air before reassembling and installing the air filter housing, with installation being the reverse of removal. For 2.5L engines, the air filter housing is incorporated into the engine cover.

How to remove the intake duct resonator and air filter box on Volkswagen Passat?

Accepted Answer

Take out the intake duct resonator screws and remove the resonator and air filter cover. Unplug the electrical contacts of the Mass Airflow sensor, power transistor, and EVAP purge valve when necessary and remove the wiring harness on the air filter cover and place it aside. On DOHC V6 models, unscrew the purge valve off the cover and set aside the purge valve and hoses. Unscrew the hose clamp and disconnect the air intake duct with Mass Airflow sensor. When it is equipped, unplug the secondary air injection pump hose at the air filter cover loosen the latches and then remove the cover along with the Mass Airflow sensor attached to it and then discard the air filter element. Removal of mounting bolt, lift the housing, and disconnect it to the grommets on the inner fender, and remove the assembly out of the engine compartment. Installation is in the opposite sequence of removal.
