User review:

I went back to the 2025 Lexus RX350 add key. Success withLonsdor K518 ProandLT20.
I brought the regular 8a ba bypass and tried to pin the can H-can L with flyer wires and failed.
I had to go grab theLonsdor 30 pin bypasson in pic 2# , it worked great for autel and Lonsdor. ( saved hours because somone cut out a huge access behind the glove box lol pic3#).

the ft portion of key does not. The prox and remote are working.
so comfort access no
But remote yes.

VNCI 6154A red dongle and Topdon Rlink J2534/Rlink X7 for VAG which is better?

Here comes the comparison between these two scanners.

Key Differences from User Feedback:
Ease of Setup and Compatibility:

• VNCI 6154 is praised for its "plug-and-play” simplicity with original ODIS drivers—no extra software or modifications needed.
  Users call it "beginner-friendly” and a "solid VAS 6154 clone” that works out-of-the-box for ODIS version till v25, including CAN FD and DoIP protocols for newer VAG models (2018+). However, some report WiFi connectivity glitches during initial pairing, requiring manual IP tweaks.
• Topdon Rlink X7 VAG requires downloading the Rlink Platform driver from Topdon’s site, binding the device via account registration, and switching modes (e.g., to J2534). It’s "straightforward for pros” but "fiddly for first-timers” due to the setup steps. It’s lauded for seamless integration with ODIS V23+ and multi-brand expansion (e.g., future GM/Ford support), but occasional driver conflicts on Windows 10/11 are mentioned.

Reliability and Stability:

• VNCI 6154gets mixed reviews: Positive for basic diagnostics (e.g., "reliable for ABS/SRS coding on a 2012 A7” per r/Audi), but users warn of firmware bugs in older versions (fixed in V1.1.7.5+). It’s seen as "cheap and functional” for hobbyists but prone to dropouts during long programming sessions (e.g., ECU flashes taking 2+ hours).
• Topdon Rlink X7 VAG shines in stability, users describing it as "professional-grade” and "robust” for reprogramming. Blogs feedback highlight fewer connection drops, thanks to its ARM Cortex-M33 processor and reinforced housing.

Build Quality and Value:

• VNCI 6154 is a low-cost option ($119 ob obdii365.com), appealing to budget users who say it "costs 10% of genuine VAS but covers 100% functions.” Reviews criticize its plasticky build and lack of official support, with some calling it "disposable” after 1–2 years.
• Topdon Rlink X7 VAG($199) is viewed as a "premium clone” with better durability and Topdon’s 1-year warranty. Buyers appreciate the "lifetime free updates” (for drivers, not OEM software) and responsive support (e.g., "fixed my VAG coding issue in 24 hours”). Some complain about no bundled OE software, requiring separate ODIS downloads.

Performance for VAG-Specific Tasks:

Both handle full-system scans, key programming, and adaptations equally well per users. VNCI excels for "quick home use” (e.g., battery swaps), while Rlink X7 is preferred for "shop-level ECU upgrades” due to faster data throughput (3 CAN channels) and DoIP/CAN FD support for 2024+ models.

Common gripes: VNCIusers report occasional "KWP2000 timing errors” on older Audis; Rlink users note it’s "overkill for simple clears” but unbeatable for complex jobs.

Overall, VNCI 6154 suits casual VAG owners seeking affordability, while Topdon Rlink X7 VAG is favored by semi-pros for reliability and expandability. No major safety issues in reviews, but always use stable power sources for programming.

Question:

I currently own a Topscan Pro. I'm looking to purchase a new Topdon device, but I'm not sure between the Artidiag Pro and the AD900 BT.

Here is the clue.

Artidiag Pro vs Artidiag 900 BT (AD900 BT).

They're pretty similar in function. Both have bi-directional control and 'special functions', and of course do all the expected scan tool stuff... read and clear DTCs, data stream, etc. They both have 7 inch screens. Their batteries are slightly different, with the 900BT having a little more capacity. The Pro has a few more service functions at 35 versus the 28 on the 900BT, but the 900BT covers more vehicles.

Probably the biggest difference is the Pro's DLC is cabled and the 900BT is wireless (Bluetooth), hence the "BT" in its model number. Both come with a two year subscription.

Here comes the problem:

Got a 2015 VW Golf cluster that has gone black after reading withYanhua Mini ACDP2 module 34. It won’t allow write back. The new cluster takes more than USD 1K+. Is there a way to reset?

There are several possible solutions:

Solution 1. Restore data (write back data). Menu path: ICP ODO- Step Mode- Step 3 Write data.

If it fails to write data,send the original cluster data to Yanhua ACDP team to modify data manually, then write back data.

Solution 2:

Try writing original data with a different tool. Xhorse is good on these clusters. Re-read withxhorse key tool plus, it is possible to repair the file online after the entire operation, Upload the file back and the dashboard came to life.

Solution 3:

Buy a sync file from a third-party to save headaches.

When it comes to mileage correction on BMW instrument clusters, particularly for EEPROM chips like the 35160WT and 35128WT, two tools dominate the conversation: theXhorse VVDI PROGand theCGPRO 9S12programmer. Here’s an in-depth comparison to help you decide which tool is best for your needs.

Background:

The Challenge of 35160WT and 35128WT EEPROM chips, such as the 35160WT and its variant, the 35128WT, are commonly found in BMW dashboards and store critical data, including mileage information. Modifying this data, particularly for mileage correction, is a delicate process due to the chips’ security features. Some use the R270 programmer with a custom board to erase the first two lines of data on 35160WT chips. While effective for the 35160WT, this setup couldn’t handle the more complex 35128WT. To explore premium options, you will need VVDI PROG or CGPRO.

VVDI PROG:

The VVDI PROG is a robust tool known for its flexibility in reading and writing EEPROM data. Here’s how it performs for mileage correction on 35160WT and 35128WT chips:

How It Works

Standard Setup:The VVDI PROG, in its standard configuration, doesn’t require additional boards for basic operations. Using its software, you select the "EEPROM” special function and choose the chip type (e.g., 35080 or 35160). The tool can read the EEPROM content, including the chip’s ID, and transfer this data to a customVVDI 35160 chip.
Mileage Correction:To adjust mileage, you can either: Replace the original EEPROM with VVDI’s custom chip (priced around £10), which allows erasing the first two lines where mileage data is stored.
Attempt to modify the existing chip. However, with standard accessories (e.g., the basic adapter board), the VVDI PROG often fails to erase or write to the original 35160WT chip, even when soldered.
Additional Adapters: VVDI offers a specialized adapter for the 35160WT, which may improve performance but significantly increases costs. This adapter has unique circuitry, unlike generic adapters, but it is discontinued.

Pros

Extensive chip support, including CAS and FRM modules.
Software is freely downloadable, allowing users to explore its features without purchasing the device.
High flexibility for reading EEPROM dumps.

Cons

Requires additional software for advanced operations like mileage correction or CAS module unlocking.
Standard accessories are insufficient for reliable 35160WT programming.

Verdict

The VVDI PROG is a powerful tool for technicians comfortable with additional software and hardware investments. However, its inability to reliably modify original 35160WT chips without costly add-ons is a drawback.

CGPRO: User-Friendly but Falls Short

The CGPRO is marketed as a more user-friendly alternative, with integrated features that simplify mileage correction. However, its performance on 35160WT and 35128WT chips was disappointing.

How It Works

Software Advantage: The CGPRO’s software is more intuitive, allowing direct mileage adjustments after reading the chip. It supports multiple reading modes and comes with a variety of adapters for different chips.
Mileage Correction:For the 35160WT, the CGPRO failed to erase the first two lines of data, where mileage is stored in "Mode 1” chips. This was surprising, as my older R270 succeeded in this task. For the 35128WT, commonly found in BMW G-series vehicles, the CGPRO also struggled. Claims of success (e.g., by a YouTuber) often involve chips in "Mode 2” or "Mode 3,” where mileage data is stored differently, not in the first two lines.
Unique Features: The CGPRO supports CAS/FRM cloning and key programming, and its software requires an internet connection to verify a valid license.

Pros

User-friendly software with built-in mileage correction functions.
Wide range of adapters included.
Slightly cheaper than VVDI PROG (~$435 with all accessories).

Cons

Failed to erase mileage data on 35160WT and 35128WT chips in Mode 1.
Limited reliability, with the manufacturer claiming an 80% success rate for certain chips.
Internet dependency for software may be inconvenient.

Verdict

The CGPRO is easier to use than the VVDI PROG, but its inability to reliably handle 35160WT and 35128WT chips makes it less dependable for BMW mileage correction.

Key Insights on 35160WT and 35128WT Chips

Both tools struggle with the 35160WT and 35128WT due to their security features. For 35160WT chips in Mode 1, mileage data in the first two lines is nearly impossible to erase or reduce, though increasing mileage is feasible. For 35128WT chips, particularly in BMW G-series vehicles, success is limited to chips in Mode 2 or Mode 3, where mileage data is stored elsewhere. A common workaround is using an emulator chip to bypass these limitations, but this adds cost and complexity.

Recommendation

VVDI PROG: ~$429 (additional adapters or chips increase costs).
CGPRO: ~$435 (includes more accessories).
Alternative: TheYanhua ACDP2is a more expensive but comprehensive tool that we’ve found to be more reliable for BMW mileage correction and other tasks.

For budget-conscious technicians, the CGPRO is easier to use but less reliable for 35160WT and 35128WT chips. The VVDI PROG offers greater flexibility but requires additional investments. Neither tool is a complete solution, and success depends on the chip’s mode and your willingness to invest in accessories or emulator chips.

Final Thoughts

Both the VVDI PROG and CGPRO have their strengths, but neither fully delivers on the promise of seamless mileage correction for BMW’s 35160WT and 35128WT chips. The VVDI PROG is better for those needing versatility and willing to navigate additional software and hardware, while the CGPRO suits users prioritizing ease of use. However, for consistent results, I recommend exploring the ACDP2 or sticking with proven older tools like the R270 for specific tasks. Always verify chip compatibility and consider the total cost of ownership before investing.

Problem:

It is a 2022 Lexus RX350. All smart keys have lost.Lonsdor K518 Probacked up immo data successfully viaADP15 adapter. But failed to generate the emulator key.

Device says "No valid key data found or PEPS is brand new” when generating emulator.

Possible reason and solution:

Someone reset the smart box.

You can back up immo data via ADP adapter, but the immo data does not contain key data. It’s like new.

In this case, Lonsdor is not be able to program key anymore.

The user needs to find someone to write the data to the smart box, or replace the Smart box with one that already has data, to proceed the key programming.

Problem:

Lonsdor K518 Prodid not read any key. I have tried yesterday too lots of keys nothing is reading.

Device gave an error key chip communication decoding error.

Solution:

There is a problem with the induction coil.

Disassemble the K518 Pro unit and check the coil area.

If you don’t know how to disassemble the device, send the device back to repair.
