1998 BMW 740iL Question: check engine light
There is no reset switch for the check engine light on your BMW 740ilL. The check engine light came on because the engine computer determined a fault with the engine control system. Please see the repairpal encyclopedia for more information about your check engine light. The check engine light can be turned off using a scan tool which can communicate with the engine control module. The light will also go off by itself after the repair has been made and certain conditions have been meet. The conditions vary depending on which fault code has been set. - Russ

Leaks are known to develop in the cooling system. It is common to see more than one part recommended for repair/replacement due to overlapping labor and the use of many plastic parts in the system.
