Intermittent Simulation

WARNING: This page is about a different car, the 1995 BMW 525iT, 1995 BMW 525i, 1995 BMW 325is, and 1995 BMW 325i. However, it is still accessible from the selected car via links, so may be relevant.

To reproduce the conditions creating an intermittent fault, use the following methods:

Lightly vibrate component.
Heat component.
Wiggle or bend wiring harness.
Spray component with water mist.
Remove/apply vacuum source.

Monitor circuit/component voltage or resistance while simulating intermittent. If engine is running, monitor for self-diagnostic codes. Use test results to identify a faulty component or circuit.
