Fuel Injector Resistance Test

WARNING: This page is about a different car, the 2001 Audi S4 and 2001 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.

Turn ignition off. Disconnect fuel injector 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.
