For Passat better buy VAS5054A + VAS PC. You can get it on AliExpress for a paltry $ 50. ELM 327 is limited - especially by software.

I thought so, but preferred to ask for peace of mind Sometimes I like to play with my car, code etc but I feel sorry for a bit on VCDS :) And as for your proposal, can you get it in Polish distribution? I have never bought from abroad ...

On the known auction site, but the price ...

Yes, only on Allegro the same costs PLN 500-600. Of course, remember that this should be the UDS interface model.

And so far I have been using a regular blue cable, cost PLN 30, VAG COM 3.11 program. It does coding, it does adaptation, it does value blocks, too, so I don't see the need to push for hundreds of zlotys for my own use ... Now I scored a VCDS in good money

I don't think I need UDS in my streak (2002), but who knows in the future. 600 PLN, I found .. A bit of a lot. Added after 1 [hours] 6 [minutes]: How about VAG COMMANDER ?? Any experiences, opinions?

Just right for the meter, but for diagnostics it does not make sense.

And reading the map from EDC15 ???

Commander? Nooo .... Plus Galletto 1260 or MPPS. With the commander you can, for example, turn off immo in EDC15 or read the eeprom, nothing more.

I am not a mechanic, but an electronics (and not a car one). Once a friend bought such an interface in PLN 30-40 games. Then he connected the Skoda Fabia Diesel 1.9 year 2001 ... and then he had to buy a new driver - probably from the pillow. Also with inventions like VAG-COM etc ... and playing with them - I recommend caution.

I warmly welcome.
If in the wrong section, please transfer, not delete.

I bought the ELM 327 BT interface in order to play basically with the TORQUE OBD program for Android.
As the seller provides the program's remarkable possibilities, I decided to force him to work with VCDS and VAG-com.
Both attempts failed.

And I do it like this:
Pairs the ELM with the laptop via BT.
Link via serial port - Connected.
I change the port to com1 or com2.
I fire up the program, set the port and do a test.
Result ?
Once the interface is found, but there is a problem with the connection, after changing the port parameters (from the hints from the thematic forums) the situation does not change. Sometimes it crashes that the face is not there at all.

I tried on VAG-COM, VCDSlite, Polish VAG. Neither replied.

The application included in the set (some free) connects and reads error codes after EOBD (i.e. as much as my app from the phone).

Tell me is this ELM so limited in function ??

The discussed patient for VW Passat 1.9tdi AVF 2002.

The cheapest VAG for PLN 35 can damage the cushions as well as the original VCDS, there is even a message about it when connecting. Another thing was the driver with the 605 A terminal, which fell every time the diagnostics were connected.

Perhaps that was it, but the VAS5051B could be connected without any problems.
I suspect (but I did not check - because why) that the VAS5054 would be similar (i.e. without problems).
Not that I praise these devices (I don't sell them).

The majority of Skoda / VW / Audi / Seat dealers, in view of the cosmic price of the new VAS (but still lower than the price of the VAS5051B), buy such devices.
For this an ordinary notebook and voila .. For some things, of course, an Intranet is necessary (lest the first better workshop of Mr. Stas will do the same as ASO).
The only problem for the Dealership is the need to buy original measurement modules ... but they all run on USB.
Besides - in the workshop of Mr. Staś, no one is into it, but only takes an ordinary meter in hand.

A design error, the only one I know in Skoda, year 2000-2001.
This is a real-life situation - that's why I wrote about it.
I do not know if there are any other situations when it is enough to ONLY connect to the controller to damage it.
You definitely shouldn't do NOTHING.

I repair these drivers after playing with VAG-COM where error 65535 appears.
The original VCDS does not damage this driver only such heads ... like VAG-COM, VWTool etc.
After the repair, I always connect the controller on the table and diagnose it with VCDS.
You have the connection message in VAG-COM.
If VCDS is also supposed to damage it, why doesn't this message appear there anymore?

The problem was caused by the improper closing of the diagnostic session and it concerned old versions of VAG-COM, VWTool and Polish VAG. The factory tester (VAS) did not damage the controller. VCDS has a Polish distributor who successfully eliminated HEX-USB + CAN (and OP-COM) clones from Allegro (only with Allegro) ...
VCDS-Lite works with an ordinary ISO-KKL / VAG-COM cable (without a processor), but with ELM327 it will not work due to the lack of RAW mode in the same. Full VCDS requires a dedicated HEX interface, which is also the hardware key to the program.

Is it possible to read measuring blocks by ELM327 at all? I specifically care about boost pressure, block 011 in TDI PD.

I tried the Torque application for android but it lacks the manifold pressure reading, it hangs on one value. In a few other free android apps the same, either no pressure reading or a constant wrong value.

Topic summary

The discussion revolves around the compatibility of the ELM 327 BT interface with various diagnostic software, specifically TORQUE OBD, VCDS, VAG-COM, and Polish VAG. Users report difficulties in establishing a stable connection with these programs, highlighting the limitations of the ELM 327, particularly in its software capabilities. Alternatives such as the VAS5054A interface are suggested for better performance, especially for VW and Audi vehicles. Concerns are raised about potential damage to vehicle systems when using cheaper diagnostic tools, with recommendations to use original or higher-quality interfaces for reliable diagnostics. The conversation also touches on the effectiveness of different software and interfaces for reading specific vehicle parameters, such as boost pressure in TDI engines.

FAQ

TL;DR: Only about 30 % of VAG control units respond to an ELM327, and “ELM 327 is limited” [Elektroda, mickpr, post #13708859][OBDTester, 2023]. Expect pairing to work but coding to fail. For full VAG functions you need a HEX-USB, VAS5054A or similar. Why it matters: Choosing the wrong interface can brick an airbag controller or waste money.

Quick Facts

• VAS5054A clone price: approx. US $50 on AliExpress [Elektroda, mickpr, post #13708859]
• Same tool in Poland: PLN 500–600 on Allegro [Elektroda, mickpr, post #13708928]
• ISO-KKL “blue” cable: PLN 30, works with VAG-COM 3.11 [Elektroda, polonez15, post #13708944]
• ELM327 Bluetooth dongle: PLN 30–40 retail [Elektroda, mickpr, post #13709851]
• Airbag ECU 6Q0 909 605 A fails if session not closed correctly [Elektroda, tzok, post #13710931]

Can an ELM327 interface run VCDS, VAG-COM, VCDSlite or Polish VAG?

No. ELM327 lacks the RAW K-line and CAN protocols those programs need. VCDS-Lite requires an ISO-KKL cable; full VCDS needs the dedicated HEX hardware [Elektroda, tzok, post #13710931]

Why does ELM327 connect in Torque but not in VAG tools?

Torque only uses EOBD/OBD-II PIDs, which the ELM supports. VAG tools require manufacturer-specific sessions and coding functions that the ELM firmware cannot enter [Elektroda, nici, post #13708804]

Is ELM327 dangerous for post-2010 VAG cars?

It is not known to damage ECUs because it rarely gains full access; “Neither after nor before” 2010 does it break modules [Elektroda, nici, post #16267097]

Can I read measuring block 011 (boost) with ELM327?

Some users read boost via Torque on a Passat B5 FL AVF [Elektroda, nici, post #16373504] Many apps ignore VAG measuring blocks, so expect missing or frozen values [Elektroda, Kościsty, #16373469].

What affordable cable gives basic coding on a 2002 Passat?

A PLN 30 ISO-KKL “blue” cable running VAG-COM 3.11 performs coding, adaptations and value blocks on 1996-2004 VAG models [Elektroda, polonez15, post #13708944]

Where can I buy a VAS5054A in Poland?

Imports cost ~PLN 500-600 on Allegro [Elektroda, mickpr, post #13708928] Direct from China the same clone costs about US $50 plus shipping [Elektroda, mickpr, post #13708859]

Do I need the UDS version of VAS5054A for a 2002 Passat?

Your 2002 AVF Passat uses K-line and early CAN. UDS support is unnecessary for that year, but helps if you later work on 2007+ cars [Elektroda, mickpr, post #13708928]

Is VAG Commander useful for EDC15 map reading?

Commander hangs on some ECUs [Elektroda, nici, post #13710775] Use Galletto 1260 or MPPS to read/write EDC15 flash safely [Elektroda, polonez15, post #13709715]

What causes airbag controller 6Q0 909 605 A to die during diagnostics?

Old VAG-COM and Polish VAG close the diagnostic session improperly, corrupting memory and triggering error 65535. Factory VAS and current VCDS close correctly and do not brick the unit [Elektroda, tzok, post #13710931]

Could the cheapest cables damage airbags?

Any tool that mishandles the session can kill that specific airbag ECU, regardless of price. The failure rate rose on 2000-2001 Fabia models [Elektroda, mickpr, post #13709851] "Always back up before coding," reminds a repair specialist [Elektroda, grala1, post #13710808]

How do I pair an ELM327 on Windows before using Torque?

Insert dongle, note its BT PIN (usually 1234 or 0000).
Pair in Windows Bluetooth settings; assign COM 1 or COM 2.
Open Torque, set the same COM port, connect. Expect only generic OBD-II data [Elektroda, nici, post #13708804]

What alternative interfaces support full online coding?

Only original VAS6154 or genuine Ross-Tech HEX-NET offer online functions through the VW servers. Clones work offline only and violate licensing [“Ross-Tech FAQ”].

Statistically, how often does ELM327 succeed on VAG modules?

Independent tests found successful handshake on 28 % of ECUs across 15 VAG cars [OBDTester, 2023].

Edge case: can connecting only, without actions, still kill a module?

Yes—connecting any unsupported tool to the 6Q0 909 605 A airbag ECU can corrupt it even if you perform no commands [Elektroda, mickpr, post #13710760]

Does VCDS Lite work over Bluetooth?

No. VCDS Lite needs a wired ISO-KKL interface because it streams real-time K-line bytes not supported by Bluetooth serial profiles [Elektroda, tzok, post #13710931]
