problem with cable and vag software

[oliew]

I bought a cable from ebay to check my s4 which has just recently been de-precatted, rs4 dps and full rs4 milltek exhaust, for maf reading and error logging, just incase theres any problems while i run it around
The cable connects ok with Vag Com but will only connect to the xenon headlights?!?!! im really confused,
the cable is a usb type but looks to use a serial emulator driver.
the guy assures me it will work with my car and version 409 of vag software i tried 311 also.
here is the cable

just tried it with a mk5 golf worked like a dream, even brought up some error codes, could connect to every module, wonder why my b5 doesnt work? i connected to the xenons on my audi and did the output tests and the xenons raised and lowered. ive tried dumb mode with the baud to 600, 1200 etc.. nothin else still

What happens after youve tested each of the comm ports - are you getting full communication

Might be a driver problem - try installing this usb driver http://images.auctionworks.com/hi/69/68 ... Driver.rar

hi mate,
comm works ok, its on com4, only thing i havent tried yet is disabling the fifo on the com port, will try that tommorow, i think im getting full communication yeah, with the golf it seemed great.
1 thing i have got is the ABS problem. i read on a forum that the abs module could stop vag connecting to other modules??? maybe i should disconnect the abs module wherever this is and try that after i try the other thing.
thanks for the link to the driver will try it!

maxximus,
tried that drive, no go im afraid! allthou it does have a few more nicer options in the properties like recieve/send size buffer and response time.
i m beginning to think its working but because my ABS is shot it wont connect to the car!! wierd how xenons did but maybe they are on a different bit.
mrc managed to get their vag connected with my car but wouldnt connect to the abs must be totally broke
maybe i should fix my abs! then try the cable, if no joy still ill get a rosstech cable!
cheers for the help

It's not unknown for timing problems to afflict certain modules with some computers. The benefit of the genuine Ross-Tech cables is that they have intelligence built in and control the signal timing, rather than relying on the computer to do it all.
