Test Steps From Test Table.
^ For vehicles on which the On Board Diagnostic (OBD) does not give any indication of the source of the malfunction: Work through the complete electrical check.
^ For vehicles on which the On Board Diagnostic (OBD) provides a direct indication of the source of the malfunction: Only carry out the test steps recommended in the Diagnostic Trouble Code (DTC) table (directed entry).
Test Requirements
^ Switch ignition and electrical consumers off before commencing the check (headlights, lighting, fan ... ).
^ Fuses S9, S15, S178 and S179 must be OK (remove fuses from fuse holder to check).
Removing Air Cleaner
^ Disconnect connector -2- at mass air flow sensor.
^ Release spring-type clip on air duct hose 1 with pliers VAG 1921 and pull hose off air cleaner.
^ Remove air cleaner bolts -3- -4- and take out air cleaner.
^ Release control module -J104- connector -arrow 1- and pull off arrow 2-.
^ Connect test box VAG 1598/36 -1- to multi-pin connector of control module -J104- -2-.
The specified values are matched to the VAG 1526 and are not necessarily applicable for other test units.

Notes on test table
^ The socket designations of adapter V.A.G 1598133 are identical to the control module -J104- contact designations in wiring diagram.
^ If the readings obtained deviate from the specifications, carry out repair measure in the right hand part of the table.
^ Continuity checks with adapter set V.A.G 1594 A (bridging).
^ If the measured figures only deviate slightly from the specifications, clean sockets and plugs of the testers and adapter cables (with contact spray G 000 700 04 ) and repeat check. Before replacing components, check wiring and connections and also, particularly for specifications of less than 10 ohms, repeat resistance check on the component.
