If the readings obtained deviate from the specifications, carry out repair measure in the
right-hand part of the table.
Electrical Wiring Diagrams, Troubleshooting & Component Locations binder
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 , repeat resistance check on the component.
