Bought a VAGCOM cable from ebay with the free version of the ross tech software, installed it using the instructions but it doesnt seem to work. When I click USB and the test button it says interface not found I've tried using all the ross tech drivers on my pc but nothing works Im running Windows Vista Home Premium on my laptop. Been told to download the latest ross tech software and try that, so I did Now when I run the program it says port ok but interface not found Plugged the cable into my mates mk3 and the blue LED lit up fine and the LED test comes back ok but still no joy Any ideas? Thanks guys
I've tried using 409.1 and also the latest version of VCDS with those new drivers but both get the same error Im updating the drivers by going into device manager, selecting the USB driver for the cable and clicking update driver..thats the right way im guessing? THIS is the cable I've bought form Ebay Any help would be much appreciated!!
Ok got the program to recognise the interface etc and once tested all the settings save. Only problem is now, once its connected to the car, it tries a few addresses a number of times and then says cant connect to controller... any ideas?
yep tried it with ignition on and car running trying it on my mates Mk3 golf 1.9 GL diesel selected the Auto-Scan thing and selected Mk3 and also tried going into the engine control module and the same thing happened all the boxes stay blank and it tries a few addresses a number of times then says cannot connect to controller
Have you tried using the "com port" that the USB lead reports as? Think mine presents itself as Com4. Works fine.
yeah that was my initial problem, wouldnt recognise the interface mine is on com3 i think so it recognises the interface etc now but cant connect to any controller
Yeah man, selected the 1H - VW G/J/V MK3 option Wish i was drunk, sober for the 1st friday in ages...blew all my money on a 1.8t engine arriving monday
how old is the car ?is it compatible,? a mate of mine has a seat toleda or something on an x reg and it doesnt comunicate with my lead,even tough i have used it on numerous different cars. in cluding his lupo
on the pc you need to go into the serial ports and make sure the cable is on the same com port as the software. the cable is not real usb its a usb pretending to be a serial cable. I would have talked you through it better but Im on my way out until the evening
Ok bit of an update, I've checked on my Vista laptop which port the usb is connected to and its com4, not 3 like i thought earlier Using vagcom 409.1 it recognises an interface as it should on com3, but not on com4 and using VCDS it doesnt recognise it on any tried all the different drivers that came with vagcom on the cd, the rosstech ones i downloaded with VCDS and the file that matt82 gave me on here and still nothing Been told you need the latest version of VCDS to run on vista which I have but still no joy The led lights up when connected to the car but cant get VCDS to find an interface, and cant get vagcom to communicate with the controller even though it scans, but with vagcom, it was using com3 and finding an interface...eventhough it was com4 thats mapped to the usb, this could be why it cant communicate to the controller as it thinks whatever com3 is working with is the interface? Tried all the drivers with all the com ports on VCDS and still no luck!! also tried it in my mates P reg ibiza earlier with the same results I love computers!!
Ive been told that vagcom sometimes recognises a modem instead of the actually interface, try disabling the modem which is probably on the com port that vagcom is recognising. If the ports arent matched it will never work. If you think it will work on 3 then change the interface port to 3 then do the same on vagcom
Changed the USB serial port to COM1, and tried using every driver with both vagcom 409.1 and the latest VCDS 805 The furthest I get is "Port: ok, Interface not found!" How do I put the lappy into admin mode? Cheers Andy
that sounds about normal until you then plug it onto the car, with ignition on, make sure its on dumb mode and then test again
Mine sets itself as COMM 4 aswell. When running it on Vista it used to crash a lot. To get it to run without crashing you need to right click on the VAGCOM icon on the desktop then go into properties, advanced settings then click on run as administrator then click apply. Thats what i had to do to run it on my laptop with Vista.
I've tried running it as an admin and no joy, same thing happens how do I put it in dumb mode? are you talking about the engine or the program? Im very new to this!! lol Cheers guys
