Your BMW Series 750iL represents the finest in automotive technology. Like all precision engineered machines, of course, the BMW Series 750iL operates at its peak within certain parameters and ranges. This requires that periodic maintenance be performed as scheduled.

Key to engine performance and efficiency is the BMW Series 750iL oxygen sensor. A certain ratio of fuel to air is vital in order for the engine to run at its best while minimizing emissions.

The lowest emissions occur when the BMW Series 750iL engine runs on a leaner fuel-air mixture - that is, when the ratio of air to fuel is higher. The BMW Series 750iL oxygen sensor detects the amount of oxygen in the exhaust gases, then delivers an electronic signal to the fuel-injection system if the mixture is too rich (contains more fuel than air). The BMW Series 750iL oxygen sensor requires the vehicle to be at running temperature to operate, so signals are not sent to the fuel injectors until the engine was warmed up. If the oxygen sensor is not operating properly, poor performance, increased fuel consumption, and foul smelling exhaust can result.
