Standard equipment is found on all vehicles regardless of which engine or optional equipment is installed. The Standard Equipment diagrams can be found at Power and Ground Distribution diagrams. These diagrams have a hyperlinked Wiring Diagram Index that lists all of the components shown within them. Click on the link for the component in question, and the link will take you to the first appropriate diagram with that component’s circuit. Engine Specific This category includes components and systems circuits such as Starting and Charging Systems, Engine Controls, Ignition System, Fuel Injection System, etc., which are unique to a specific engine. The Engine Specific diagrams can be found at Powertrain Management diagrams. These diagrams have a hyperlinked Wiring Diagram Index that lists all of the components shown within them. Click on the link for the component in question, and the link will take you to the first appropriate diagram with that component’s circuit. System Specific and Optional Equipment This category includes equipment such as Air Bag Systems, Anti-lock Brake System, Heated Seats, HVAC System, Comfort System, etc. and provides circuit details for those systems and components

1. Use a scan tool to monitor the fuel trim numbers and the Mass Air Flow (MAF) sensor data stream grams/sec readings. Nominal
values are 5 grams/sec at idle in Park, and >150 at Wide Open Throttle (WOT) and 5000 RPM, in gear. Some scan tools have a freeze frame feature, which is useful in trouble shooting if the problem is set at idle versus at cruise. Vacuum leaks and crankcase breather problems generally show up at idle. Voltage at the airflow meter should be .7-.9V at idle and increase from there with more airflow. 2. Monitor the crankcase vacuum with a vacuum gauge, which can be adapted onto the tube for the oil dipstick. Specification for the crank case vacuum is 8 to 15 millibar, this equals about 1/4 to 1/2 PSI or pounds per square. So, 1 PSI of vacuum would be twice as much as there should be at idle. The proper method, per BMW, is to use a slack tube manometer which can be made easily with clear tubing and making it into a U shape and have it marked in inch increments then half fill it with water. When crankcase vacuum is applied to one side of the tubing it should displace 4 to 6 inches of water if the crankcase breather is working correctly. 3. Monitor the fuel pressure. It should be a constant 50 – 53 PSI.
