Using CHECK ENGINE Light

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.

When repairs have been completed, clear diagnostic codes from memory. To clear codes, turn ignition off and disconnect and reconnect negative battery cable. Alternative methods are starting engine 60 times without a repeat of failure or using BMW Service Tester. See USING BMW MODIC OR BMW SERVICE TESTER under CLEARING CODES .

NOTE: Disconnecting negative battery cable may also erase pre-selected settings for radio, seat memory, trip computer, etc.
