When it comes to key programming for vehicles with Audi’s encrypted BCM2, particularly software version 0711, automotive locksmiths and technicians face significant challenges. Two of the most popular tools in the industry for tackling this task are the Xhorse VVDI series and the Autel IM608. However, when dealing with such sensitive operations as those involved with Audi’s encrypted BCM2 units, it’s crucial to choose the right tool to minimize risks and ensure success.
Autel IM608 with XP400 Pro
The Autel IM608 is a comprehensive key programming and diagnostic tool that, when paired with the XP400 Pro, is capable of handling encrypted BCM2 modules. It’s important to note that the XP400 Pro is an advanced version of the XP400 and is necessary for dealing with encrypted BCM2, as the XP400 cannot read BCM2 encryption.
Advantages:
– The XP400 Pro can read more chip types and unlock certain locked keys that its predecessor cannot.
Drawbacks:
– There is a risk of damaging the BCM2 during the reading process. An example of this occurred when attempting to read an encrypted BCM2 with the IM608 and XP400 Pro. The procedure started correctly, but after reading some data and attempting to calculate, a network error occurred, and the BCM2 unit became non-responsive.
– In this situation, BCM2 recovery was not possible because the file saved by Autel was not supported, resulting in the need to replace the BCM2 entirely.
Procedure:
– Autel requires the use of diodes (1N4001-1N4007) when working on encrypted BCM2 modules. However, if the process fails, as in the example provided, the only solution may be to purchase a new BCM and dealer key and use ODIS for programming.
Xhorse VVDI2 or Key Tool Plus
In contrast to the Autel IM608, many professionals prefer the Xhorse VVDI2 or the Key Tool Plus for Audi key programming tasks. These tools, especially when used with the BCM2 adapter, provide a solder-free solution that is often regarded as more reliable and user-friendly for VAG vehicles.
Advantages:
– No soldering is required with the BCM2 adapter, reducing the risk of damaging the unit.
– The Xhorse tools can complete the BCM2 all key lost (AKL) process relatively quickly, typically within 30 minutes.
– Xhorse also has the capability to clone locked BCM units, provided you have the same hardware and software versions and service data.
– The VVDI series is reported to work seamlessly, even on cars that won’t crank, by boosting the car to over 12 volts and relearning the key, followed by clearing any diagnostic trouble codes (DTC).
Example:
– A successful BCM2 AKL job was completed using the VVDI2 and VVDI Prog, showcasing the tools’ capabilities in cloning locked BCM and ease of use.
Conclusion
Given the complexities and risks associated with Audi encrypted BCM2 key programming, choosing a reliable and effective tool is paramount. While the Autel IM608 with XP400 Pro has the capability to work on these modules, there is a notable risk of BCM2 damage during the operation. On the other hand, Xhorse’s VVDI2 or Key Tool Plus, particularly with the BCM2 adapter, offer a more secure and straightforward approach, making them a preferred choice for many professionals in the field.
When working with high-risk software versions like 0711, it’s crucial to evaluate the tools available meticulously and consider the potential costs of an unsuccessful programming, such as having to replace the BCM2 unit. Ultimately, the decision between Xhorse and Autel will depend on the technician’s experience, tool preference, and willingness to accept the associated risks.
