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 6154 gets 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: VNCI users 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.

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.

Yanhua ACDP2 VAG MQB Cluster Turn Black Solution

 Here comes the problem:

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

Yanhua ACDP2 VAG MQB Cluster Turn Black 1

There are several possible solutions:

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

Yanhua ACDP2 VAG MQB Cluster Turn Black 2

Yanhua ACDP2 VAG MQB Cluster Turn Black 3

Yanhua ACDP2 VAG MQB Cluster Turn Black 4

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 with xhorse 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.

BMW FEM Replacement with Autel + Yanhua ACDP + ISTA

 2012 F30 FEM replacement because the old one was faulty and causing door and window issues and turns out couldn’t read coding on bench for some reason. Done with Autel IM508S, Yanhua ACDP, and ISTA+.

Used Autel to do ECU upgrade on the replacement used module as the SV was too old for ACDP. The upgrade was successful.

There wasn’t any conformal coating around the EEPROM so I’m assuming the original had work on it before. EEPROM was readable no problem but couldn’t back up coding getting ‘check connection’ errors although the connection was fine. Same thing with both ACDP and using test platform with Autel. Neither could backup coding or read it. so just decided to do a calculation data replacement instead with ISN.

Got ISN from DME. Preprocessed then did calculate data replacement with ACDP to match it. New keys added. Working after putting modules back.

Finished programming in with ISTA+.

The driver’s door locks and windows are working again.

 

Is there a way to find out suitable FEM by numbers?

Match the main part number plus whether it’s a MAX or MID and it’s usually fine but expect to have to do coding and programming in esys or ISTA to match everything.

Yanhua ACDP2 Benz HU6 Cluster no AMG Logo after Mileage Correction?

Problem:

Used Yanhua ACDP Module 37 hu6 for instrument ( IC177 )  yesterday, car was full AMG with amg options in cluster etc .  Mileage correction successful but after refitting cluster module cluster is now basic A class with no AMG logos , or options. wrote back original saved coding data , Customer understandably VERY UNHAPPY !!!   cluster should have SUPERSPORT option like the centre display ????   


Update: 

managed to fix this but not with ACDP alone.  wrote back full back up with ACDP which returned cluster and mileage to full function.. Would recommend using special function and reading Pflash , Dflash and boot separately. Then did mileage with another tool and all worked fine.  There is a software error with ACDP when working with AMG cluster module as it returns the module to base model spec.
