Just got one and not sure about a few things.
First of all, where do I find this address 666.....
2nd I can pair the device but that's about it. It specifies "make sure green light is on", mine; red. yellow and green light up briefly when connecting and then remains red. Is it not compatible with the vehicle? Mercedes ML320CDI 2005 or is it a dud?
As you could read above, now the list of "bad" adapters does not limited with version that have MAC address "66:....", unfortunately in a risk zone any low priced models. If you want to see the MAC address, it's possible to see in a line next to adapter name in Connection settings or when searching, selecting the adapter.
The color coding now also could vary for different manufacturers, so one could not relay only on a green, that's from old times.
Mercedes in 2005 and by fact much earlier have compatibility with OBD-II and so should be supported with real ELM327 and our app.
If you have issues with connection please follow the instruction below to send us connection protocol for review:
- turn on/off Bluetooth in phone (or reload phone)
- start car's engine
- unplug/plug back the adapter, check that it's powered
- increase commands delay: Settings-Test-Commands delay-Long
- turn on Debug logging: Settings-Logging-Debug logging
- start app, try to connect and wait connection or error message
- send us the debug log: Settings-Logging-Send message
in a letter with log please repeat the issue description, car model/year and information about adapter
Thanks!
Is the ODBII bluetooth adapter "KW902 ELM327 V1.5" is know to be reliable ?
Thank you.
Sad to read this as I got all excited about checking codes and having my inovative dashboard for my GMC´56 Project with an LT1 FI OBDII as I even bought a Samsung Tablet to serve as Speedo, Tach, temp, MPG, etc... and music, why not?!
Has not worked or paired. First try and engine began to make some small explosions and at some point, in another attempts, switching to on and before starting the engine I could hear the gas pump working without stop. Fortunetelly that I disconnected it and engine came back to normal. But it was scary.
IS THERE A GOOD AND RELIABLE OPTION THAT I CAN USE ? Would really like to have the "digital" gauges, scanner and other apps from my Tablet with a safe OBDII reader-bluethoot.
Here is some basics to start reliable OBD solution.
The most popular on the market are solutions named as "ELM327". That is combination of chip-set(s) ad firmware designed and supported by company ELM Electronics, Other high quality competitor is OBD Solutions with their STN1110, that is compatible with ELM327 at commands level. The most reliable solutions are based on their chips and usually priced over $50 (as only chips itself is around $20). Known adapter's brands that works with original chips are for example PLX Kiwi and OBD Link.
Most of other adapter with prices less than $50 usually based on clones of ELM327 with absolutely different quality, it's really hard to qualify that products as all might use the same name but have VERY different quality. Ranged from the almost perfect to complete garbage.
Thanks!
Not sure what others of you think of konnwei adapters, but i bought an adapter from walmart.com by them, and the seller had 82 % rating... it costed 15$ and seems to work with my 2004 buick regal... it's a black device with red rubber surround near the top that says 'konnwei' on it, and also it has a power button on it... havent noticed any problems with it like the ones I see here, although I only had it a few days... and like many here i use torque pro, currently...

I have Passat CC 2012.
Is it fruitful to buy "Vgate iCar 2 ELM327 Bluetooth OBD2 Car Auto Diagnostics Scanner"
Purpose is to scan error code and fix few lights on dashbaord. I will be still happy if device only scan error code.
"Vgate" is Ok, if that is original product from www.vgate.com.cn Unfortunately it's practically impossible to say "what's inside" without testing. A lot of no-name manufacturers produce adapters that labeled as iCar 2 but unfortunate it's hard to say if they use the same chip and firmware
I have purchased OBD Advance scan tool from daraz.com but it won't works. The connection to ECU is not established and I think I have wasted my money.
this 03 january 2019I bought ELM 327 "Mini". It's blue color product and just like the ono ofe in the photo on the Bluetooth OBD adapters thread.It's address: 66:35:56:78:90:ABIt identifies as "OBD II" & "ELM327 v2.1"It comes with CD apps with several different OBD apps. for other apple phone, It sold in wish website vendor.since they improvished own apps believe its suit its own purposes, again my car is VW year 2002 meanwhile passat do assemble in PRC right now and they have been this market quiet awhile now, anyway thanks for the update now is 2019, how competition keeps customers value for their monies
You say Vgate is reliable. I'm guessing many on ebay that say Vgate aren't really Vgate. How do you know which are real?
Is Vgate a real company or just another made up Chinese brand? If you google it, it just goes to obdinnovations.com, which is just a reseller, who also sells the same $1 V2.1 junk that's on ebay, that many have problems with.

What about this one?
https://www.amazon.com/d/Automotive-Code-Readers/Vgate-Bluetooth-Diagnostic-Scanner-Check-Android/B07DCHWP9P
This review says it doesn't have an ELM327 chip:
https://www.amazon.com/gp/customer-reviews/R3HKKPT7MLGZWC/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B07DCHWP9P
FYI, this review seems to be by the poster in on this thread (rogersride).
So it seems Vgate is not a good brand.
What about BAFX? Is that just a company putting their brand label on the same cheap Chinese fake ELM327 units?
What about these?
https://mycarneedsthis.com/best-bluetooth-obd2-scan-adapters/
Absolutely agree... and we stated near the same, if teview the thread. Now doezens of Chinese factories sell different products with different characteristics and quality, but packed and labeled as Vgate. The same for other brands as well.
