Are you using Vista? If so you might need different drivers. I have Vista drivers for my generic cable and they might work with yours. Also, for me, I have 4 usb ports on my laptop and only 1 works with the vag-com. I don't use 409. as I had problems and instead use 311.

im using xp.. i tried bothusb(ihave onlytwo on my laptop)ill try 311 tomorow.. can i do the same stuff with 311??

thanks for replying

 

I've never noticed a difference between 409 and 311. So far I have been able to do everything I need with 311. When you start 311, select the options button and make sure you try all 4 com ports. Does the vag-com see the car and is unable to read? Do you get "Vag-com: interface check" Can't access Com4"?

also make sure ur key is turned but your car isnt started ... or it wont read ur car

 

k with the 409.1 vag com it says for port COM4 "Port Status:OK, Interface: Found!, pass through serial"
but when i go to read the "35 Centr. Locks" itreads some stuff and comes up with"No Response from Controller!"

and with 311.2 ports COM1-3 are "COM Port Status: Innaccessible" but for port COM4 it says "COM Port Status: OK, Interface Status: 5 - Modem!".. then when i go and attempt to access the "35 Centr. Locks" it says "Interface Status = 5, Interface Not Ready!, Possible Reasons...."...

keep in mind it says the same stuff even when i dont even plug the wire into the laptop. maybe driver issues?

 

Very well could be a driver issue. email me at (pm me for email address) and I will send you a different driver to try. 311 for me says interface not found or ready if the cable is not plugged in so something is up. Also do some research here: http://forums.audiworld.com/vag/

Be careful when posting questions on the vag-com forum as people are pissy when it comes to generic ebay cables.

oh thanks for the help everyone.i found out what it was.. i went into device manager and seen that when i plugged in the usb-serial cable it came up as COM7, vag com dosnt have that, only COM's 1-4.. so i went into advanced settings in the device manager and change the cable from COM7 to COM1 (1 was "unasigned").. after that when i plugged it in and tested COM1 everything worked..

again thanks

 

This post is very helpful.
Seems like i am going to place an order for that cable as well.
