2003 BMW 525I 2.5L Check engine light on and fault codes stored Vehicle running normally

1. Based upon stored fault codes for secondary air system, there is little or no flow of secondary air into engine. Typical causes for this issue are failed secondary air pumps and/or secondary air check valves. Secondary air pump should operate under normal circumstances when vehicle is first started to perform system test. Pump will normally be heard running when standing in front right corner of vehicle. 2. The secondary air pump is located in the right front of engine compartment. A secondary air pump relay located in the glove box is controlled by the engine control module and sends power to the secondary air pump. 3. Air pump can be disconnected and supplied with power and ground at pump to verify operation is possible. 4. Check valve on front right of cylinder head can be supplied with vacuum and visually checked for opening of valve. 5. Vacuum line from check valve to operating solenoid should also be inspected for cracks or being disconnected. Vacuum line follows right side of cylinder head to back of cylinder head to the secondary air solenoid located under left rear side of intake manifold. 6. The solenoid should allow vacuum flow to the check valve during vacuum pump operation. The solenoid is controlled directly by the engine control module and receives power during key-on-engine-off. Potential Causes: A.I.R. Check Valve Engine Control Module (ECM) Codes — Engine control module fault.

Verify that the coolant is at proper level in the radiator and the coolant recovery bottle. If the coolant is low, add proper amount of 50/50 water and DEX-COOL® mixture. If the low coolant light operates properly, diagnose the cooling system for loss of coolant as outlined in SI. DO NOT proceed further with this bulletin. 2. Remove the low coolant level sensor. Refer to Coolant Level Module Replacement in the Engine Cooling sub-section. 3. With the key on, the engine off and the coolant level sensor disconnected from the vehicle wiring harness, observe the low coolant light: Subject: Low Engine Coolant Level Indicator Always On (Diagnose Low Coolant Level System Operation/Check Sensor for Oil Contamination) Models: 2000-2002 Buick Century, Regal 2000-2001 Chevrolet Lumina 2000-2002 Chevrolet Impala, Monte Carlo 2000-2002 Pontiac Grand Prix 2000-2002 Oldsmobile Intrigue • Light is on — Chassis wiring or instrument cluster concern. Follow the appropriate diagnostic information in SI. • 4. With the key off, connect the coolant level sensor into the vehicle’s wiring harness. Connect a ground wire (1) to the battery negative terminal. Using a sharp probe (3) attached to the ground wire, ground the coolant sensor probe (2) as shown in the illustration. Make sure a good contact is made. With the key on and the engine off, observe the low coolant light for at least 15 seconds. 5. Using a small wire brush or emery cloth, polish the low coolant level sensor probe to remove any film or oxidation. The probe should be a bright brass color when finished. Use Brake Parts Cleaner to flush removed deposits from the low coolant sensor probe. Reinstall the low coolant sensor into the vehicle and proceed to Step 6. 6. Flush the cooling system and install new DEX-COOL® mixture as outlined in the SI. Check the vehicle’s warranty history to determine if any engine gasket had recently been changed. If there has not been a recent gasket replacement, locate and repair the source of the engine oil contamination

Tests/Procedures: 1. Use a scanner and command the air pump on with the engine running at idle. Check if the O2 sensors go lean. 2. If the O2 sensor does not go lean on one bank, see if the check valve at the exhaust manifold is stuck closed, not allowing air into the manifold.

How to identify a Volvo Penta gas engine

To help you easily find parts and service information about our products, Volvo Penta has developed online search tools that are available only on our website, Partner Network. As an example, in April, 2005 we launched a serial number search for all engine and transmission products. You can enter the product’s serial number and the system will provide you with all of the catalogs, manuals and bulletins that apply to that product. The system also provides links to online versions of these documents. New tools such as this are added perodically to make it easier for you to find information about the Volvo Penta products you are servicing. This is another way to insure that you have the latest, most current information about our products. Contact your dealer business specialist to sign up for the Partner Network. The parts and service technical information is organized around the model names of the products. Each manual or catalog covers specific models (product names). Understanding these model names will help in finding the correct parts and information for the products, whether you’re searching on-line or in paper publications. The text that follows explains the model names used by Volvo Penta for gas engines. Several methods have been used to provide the gas engines with unique model names. Some were based on horsepower ratings. More recent names are based on the displacement of the engine in liters. Each time the name was changed, it was due to some change in the parts content of the engine. Sometimes the changes were minor, sometimes they were major. The changes may or may not affect the parts that you need for a repair. The safest method is to always search with the complete model name. There are three distinct periods of gas engine production, each with a different naming method. Each is explained below; Red Engines, early
