Fuel Injector Resistance Test
WARNING: This page is about a different car, the 2002 Audi S4. However, it is still accessible from the selected car via links, so may be relevant.
Turn ignition off. Disconnect suspect fuel injector 2-pin harness connector. Using a DVOM, measure resistance across fuel injector terminals. See FUEL INJECTOR RESISTANCE table. If resistance is not within specification, replace fuel injector.
