What Does the 5087 BMW Code Mean and How Do You Fix It?

The 5087 Bmw Code indicates a problem with the gear selector switch, often resulting in transmission issues and limited driving modes. Diagnosing and resolving this code promptly is crucial to restoring your BMW’s performance. Contact AutoExplain.com for expert assistance.

1. What is the 5087 BMW Code?

The 5087 Bmw Code is a diagnostic trouble code (DTC) that refers to an issue with the gear selector switch, also known as the shift lever module. This switch communicates the driver’s gear selection to the transmission control module (TCM). When the TCM detects a discrepancy or malfunction in the signal from the gear selector switch, it triggers the 5087 code. This issue often manifests as problems with gear selection, the inability to shift into certain modes, or a general malfunction of the transmission system.

1.1 What are the Common Symptoms Associated with the 5087 Code?

Several symptoms can indicate the presence of the 5087 code in your BMW:

• Limited Driving Modes: The car may be stuck in a specific mode, such as sport mode, without the ability to switch to drive or manual modes.
• Inability to Shift Gears: Difficulty or failure to shift gears properly, leading to a compromised driving experience.
• Transmission Malfunction Indicator Lamp (MIL): The check engine light or transmission warning light illuminates on the dashboard.
• Erratic Shifting: Unexpected or harsh gear changes.
• Gear Selection Errors: The instrument cluster may display an incorrect gear selection.

1.2 What are the Potential Causes of the 5087 Code?

The 5087 code can be caused by various factors related to the gear selector switch and its connections:

• Faulty Gear Selector Switch: The switch itself may be defective due to wear, damage, or internal component failure.
• Wiring Issues: Damaged, corroded, or loose wiring connecting the gear selector switch to the TCM can disrupt the signal.
• Connector Problems: Corroded or damaged connectors can prevent proper communication between the switch and the TCM.
• Software Glitches: Occasionally, software issues within the TCM can lead to misinterpretation of the gear selector signal.
• Physical Damage: Damage to the shift lever mechanism or surrounding components can affect the switch’s operation.

2. How to Diagnose the 5087 BMW Code: A Step-by-Step Guide

Diagnosing the 5087 code requires a systematic approach to identify the root cause of the problem. Here’s a detailed step-by-step guide:

2.1 Preliminary Checks

Before diving into more complex diagnostics, perform these preliminary checks:

1. Visual Inspection: Examine the gear selector switch and its surrounding area for any obvious signs of physical damage, such as broken parts or loose connections.
2. Wiring and Connectors: Inspect the wiring harness and connectors associated with the gear selector switch. Look for frayed wires, corrosion, or loose connections.
3. Battery Voltage: Ensure the battery voltage is within the normal range (typically 12.6 volts or higher). Low voltage can sometimes cause electrical issues that trigger false codes.

2.2 Using a Diagnostic Scan Tool

A diagnostic scan tool is essential for accurately diagnosing the 5087 code:

1. Connect the Scan Tool: Plug the scan tool into the OBD-II port, usually located under the dashboard on the driver’s side.
2. Read and Record Codes: Turn on the ignition and use the scan tool to read and record all stored DTCs, including the 5087 code.
3. Clear Codes: Clear the codes and take the vehicle for a test drive to see if the 5087 code returns. This helps determine if the issue is intermittent or persistent.
4. Review Freeze Frame Data: If the code returns, review the freeze frame data associated with the 5087 code. This data provides a snapshot of the vehicle’s operating conditions when the code was triggered, which can offer valuable clues.

2.3 Testing the Gear Selector Switch

To verify the functionality of the gear selector switch, perform these tests:

1. Continuity Test: Use a multimeter to check the continuity of the switch’s circuits in different gear positions. Refer to the vehicle’s wiring diagram to identify the correct pins for each gear.
2. Signal Voltage Test: Measure the voltage output from the switch as you move the gear selector through each position. Compare the readings to the specified values in the service manual.
3. Resistance Test: Check the resistance of the switch’s internal components. Abnormal resistance readings can indicate a faulty switch.

2.4 Checking the Wiring and Connectors

Thoroughly inspect the wiring and connectors:

1. Wiring Diagram: Obtain a wiring diagram for the gear selector switch circuit. This diagram will show the wire colors, pin locations, and circuit pathways.
2. Continuity Test (Wiring): Use a multimeter to check the continuity of each wire in the circuit. Look for open circuits or shorts to ground.
3. Voltage Drop Test: Perform a voltage drop test to identify areas of high resistance in the wiring. Excessive voltage drop indicates a problem with the wiring.
4. Connector Inspection: Carefully inspect the connectors for corrosion, bent pins, or damage. Clean or replace any faulty connectors.

2.5 Testing the TCM (Transmission Control Module)

Although less common, the TCM can sometimes be the cause of the 5087 code:

1. Software Update: Check if there are any available software updates for the TCM. Outdated software can sometimes cause communication issues.
2. TCM Diagnostics: Use a diagnostic scan tool to perform specific TCM tests, such as input/output signal tests and internal circuit checks.
3. TCM Replacement: If all other tests pass and the TCM is suspected to be faulty, consider replacing it with a new or refurbished unit. Note that the TCM may need to be programmed to the vehicle.

3. Common Mistakes to Avoid During Diagnosis

Several common mistakes can hinder the diagnostic process. Here are some pitfalls to avoid:

• Ignoring Basic Checks: Overlooking simple issues like loose connections or damaged wiring can lead to misdiagnosis.
• Rushing the Process: Avoid rushing through the diagnostic steps. Take your time to perform each test thoroughly.
• Assuming the Switch is Bad: Don’t immediately assume the gear selector switch is faulty. Perform all necessary tests to confirm the diagnosis.
• Neglecting Wiring Diagrams: Failing to use wiring diagrams can lead to incorrect testing and inaccurate results.
• Using Low-Quality Scan Tools: Inexpensive or unreliable scan tools may provide inaccurate readings or incomplete data.
