5. Interpreting Advanced ID Data: Key Fields

Let’s break down some of the key fields in the Advanced ID data and what they mean:

Part Number: This is the most basic identifier for the module. Make sure this matches the expected part number for the vehicle and module type.
Software Version: This indicates the specific software version running on the module. This is often a key indicator of whether the module has been updated.
Coding: This represents the module’s configuration settings. Incorrect coding can lead to various problems.
Flash Status: This section provides information about the module’s flash memory. “Programming Attempts” indicates how many times the module has been flashed. “Successful Attempts” shows how many flashes were successful. “Programming Status” provides a code indicating the current state of the flash memory.
Serial Number: A unique identifier for the specific module unit.
Date: The manufacturing date of the module.

6. Identifying ECU Software Version: Answering the Original Question

In the example provided in the original question, the user is trying to determine the ECU software version and whether it has been changed. Here’s how to interpret the data:

Address 01: Engine Control Module
Part Number: 03L 906 022 TP
Component and/or Version: R4 2,0L EDC G000AG 5763
Software Coding: 0000078
Work Shop Code: WSC 06402
VCID: 0603B34371FD7A71D3-8052
Advanced Identification
Serial number: Identification: RB8-658
Revision: 13H14---
Date: 16.11.11
Test stand number: 1348
Manufacturer number: 0042
Flash Status
Programming Attempts: 0
Successful Attempts: 0
Programming Status: 00000000
Required Conditions: 00000000
Flash Tool Code: 00000 000 00000
Flash Date: 00.00.00
Software I3WF
Misc.
Hardware number: 03L 906 022 GP
Lot Number: 78
Type Lock: Car Info
Chassis Number: VSSZZZ1PZCRXXXXXX
Engine code: CEG
VCDS Info:
VCID: 0603B34371FD7A71D3-8052
Labels: 03L-906-022-CBA.CLB
Readiness: No script available

Software Version: The most likely candidate for the ECU software version is I3WF under the “Software” heading. The number 5763 that suffixes “Component and/or Version: R4 2,0L EDC G000AG” could also be a version number, but it’s more likely a component identifier.
Flash Status: The “Flash Status” indicating all zeros strongly suggests that the ECU has never had a software update applied. If the dealer were to perform a software update, these values would change. The “Programming Attempts” and “Successful Attempts” would increment, and the “Programming Status” would reflect the new state. The “Flash Date” would also be updated.

Therefore, to answer the original questions directly:

Yes, VCDS can read the Advanced ID information from modules.
The ECU software version is likely I3WF.
The all-zeros “Flash Status” is a reliable indicator that the ECU hasn’t been updated.

7. What Happens When an ECU is Flashed?

When an ECU is flashed (reprogrammed), the existing software is replaced with a new version. This process typically involves:

Connecting to the Vehicle: A diagnostic tool (like VCDS or a dealer’s proprietary tool) is connected to the vehicle’s OBD-II port.
Identifying the ECU: The tool identifies the specific ECU to be flashed.
Downloading the Update: The new software version is downloaded from a server (usually the manufacturer’s).
Flashing the ECU: The new software is written to the ECU’s flash memory. This process can take several minutes or even longer.
Verification: The tool verifies that the new software was successfully installed.
Coding and Adaptations: After flashing, the ECU may need to be recoded or adapted to the vehicle.

After a successful flash, the Advanced ID information will reflect the changes:

The Software Version will be updated to the new version number.
The Flash Status will change to indicate that a successful flash has occurred.
The Flash Date will be updated to the date of the flash.

8. The Importance of Documenting Before and After Scans

As the original poster intends, documenting the Advanced ID information before and after a service is critical, especially if there’s concern about unauthorized software changes. This provides concrete evidence of the ECU’s state. If the “Software Version” or “Flash Status” changes without your consent, you have proof that an unauthorized update was performed.

9. Potential Risks of Unauthorized ECU Updates

While software updates can improve performance, fix bugs, or address security vulnerabilities, unauthorized updates can have negative consequences:

Emissions Violations: As the original poster fears, dealers might apply emissions “fixes” that degrade performance or fuel economy.
Performance Issues: Incorrect or poorly implemented updates can cause drivability problems.
Module Damage: In rare cases, a failed flash can damage the ECU, requiring replacement.
Warranty Issues: Unauthorized modifications can void your vehicle’s warranty.

10. Protecting Yourself from Unauthorized ECU Updates

Here are some steps you can take to protect yourself:

Communicate Clearly: When taking your car in for service, explicitly instruct the dealer not to perform any ECU updates without your express consent. Put this in writing on the repair order.
Use a Written Agreement: Have the dealer sign an agreement form stating they will not alter the ECU software.
Perform Before and After Scans: Use VCDS or another diagnostic tool to record the Advanced ID information before and after the service.
Monitor for Changes: Carefully compare the before and after scans for any unexpected changes to the software version or flash status.
Seek Legal Advice: If you suspect an unauthorized update, consult with an attorney specializing in automotive law.
