Hey folks, not sure if anyone on here has bought one of these cables either:

Now the problem is this, I followed the instructions but the cable is not recognised by my laptop (running windows 8).
I’ve sent an email to bag-diagnostics but wondering if any of you have a quick fix

I have a similar cable and could only get it to work in a specific usb port on my laptop - Had to be a usb 1.1/2.0 port not the later 2.2/3 type, only got Windows 10/Linux so not sure if that applies to win 7/8

Ok so I tried the cable in all 3 USB ports (2 x blue and 1 x black). It did not register in the black port however it came up in the Devices section:


I opened the properties to check it was working:


I thought OK it’s seeing it so I ran the VCDS but got this message:


I’m at a loss, have emailed vag-diagnostics 3 times but not had any response as yet
Does anyone else have any ideas please.

Have you got anything else you can plug it into? Eg a desktop computer. Just to rule out a problem with the cable itself.

Have you got any other software installed ?
Try disabling Wifi, Disable any anti virus running , plug cable in the launch vcds

Just looking around there seem to be many "chinese" cables that do not work ......did you update the vcds software by any chance ?

So a wee update:
I couldn’t get the supplied software to work on laptop so tried it on my Mums desktop PC and it loaded OK
Contacted vag-diagnostics who then sent a link for an updated software, this worked on laptop. Now I can’t get the cable to read when connected to OBD port
The cable registers on laptop, I open VCDS and run a TEST of cable and it registers but says nothing connected to car’. When I connect the cable to OBD port and turn on ignition there is a green LED lit up which I would expect, however, every time I try to read or test I get the same error message:


Anyone had this or can help (vag-diagnostics are not the most helpful )

Did you turn the electrics on the car before you started the app? Do you have another usb port on the laptop you can try? I've had something similar before. I believe it comes down to whether it's a powered usb port or not. If it's a more modern laptop it might have different coloured usb ports (blue being the newer). Another option would be to try a powered usb hub.

The cable only works in one usb port. I tried all ways:
- Open VCDS, plug cable into laptop, run test then plug other end into OBD and turn on ignition
- plug cable into laptop, open VCDS, run test then plug other end into OBD and turn on ignition
- plug cable into laptop and OBD, open VCDS, run test and turn on ignition
- plug cable into OBD, turn on ignition, open VCDS then plug cable into laptop

Update:
Not getting anywhere with this damn cable, so bought a handheld coder


This used via an app (Xhorse) and took all of 10mins to clone new transponder.


Now I’ve got 2 x 3 button remotes working
