Intermittent Failures

WARNING: This page is about a different car, the 1993 Audi 90 and 1993 Audi 100. However, it is still accessible from the selected car via links, so may be relevant.

When an intermittent failure occurs, MIL comes on and code sets. Scan tester displays "SP" to identify code as sporadic (intermittent). If fault does not recur within 50 engine starts, code will automatically be erased. Intermittent failures may be caused by problems with a sensor, connector or wiring. See INTERMITTENTS in the TESTS W/O CODES article in this section.
