Hi
Looking for a bit of help with the vcds reader
Plugged it in and set the com port all OK
done a complete scan and showing no errors
Then scanned engine,airbags etc and all came up with controller not responding
Any ideas?
Cheers Alan

Is this actual VCDS / lite with a laptop?

Sometimes 'not responding' issues can be resolved by adjusting the baud rate and trying to link up again. My VCDS will not speak to the ECU of our 1.4i (Magnetti Marelli), whereas my VAG401 ODB reader will without issue (and will communicate with almost all of the other ECUs including Tdi engine ECU throughout the car with one important exception - it won't talk to the Climatronic controller on any of our 3 A2s, whereas the "proper" VCDS (even lite version) will.

How do you check the baud rate?

Off the top of my head it’s either in the settings of the program or in device manager for the comm port itself

Have you tried again starting fresh. The install is probably good but perhaps Baud Rate needs slowing down. Curious why when you did the complete scan and had no errors you then went into modules? Did you close controller each time?

Also worth trying the vagusb98 driver from Gendan UK (Google Gendan vcds vagusb. exe download) .
Its a .exe, so will install itself. Then check the comm port it on (Device Manager). If it's on 1 - 4, that's OK, if it's on 5 up, reassign it to 1, 2, 3 or 4. Worked for me on my old XP machine.
Didn't touch comms settings, left at defaults.
Mac.

Also how good is your battery? This does trigger communication errors. Try with the engine running to see if it communicates then.

1 - check your COM port settings at Windows Device manager, response time should be 1 ms and rate you can set 38400
2- run VCDS as admin.

Regards.

Could you try your vcds setup on another pre 2005 vag car? You'd know then if it's your setup or the car. Might save a lot of blind alleys.
Mac.

PS: Or a known working setup on yours ...
