Vag Com Doing My Head In!

[wilkinsonbaz]

hi all, hope someone can come up with the solution to my vag com hassle!!

about a year ago bought cheap ebay cable, downloaded vcd lite hooked it up had to do com port settings, drivers etc but worked a treat, used measuring blocks, communicated with car and sorted out my faults etc

then just after xmas abs light came on so thought ah laptop out vagcom cable hooked up, it was the same laptop, cable, software, car-mk1 99t 110bhp tdi.

hooked it up ignition on vcd says "port ok interface not found"

so after several attempts bought another cable slightly more expensive still same results, so since then have tried another laptop, changing drivers, port numbers, tried all usb ports on both laptops, installed a fresh version of xp, tried disconnecting car battery, tried 409.1 software, searched the internet and spoke to cable supplier all gave no better results, there must be something im missing or can it be that the ecu goes faulty and just wont connect some times, the cable led is on when hooked up.

its really doing my head in ahh!!!

so hope someone out there can help

thanks baz

Hi gregers

thanks for reply but tried com port settings in advanced screen etc

and if i swap cable to different usb port xp says new hardware found. Loads driver then says new hardware

ready to use gives it a different port number which I've tried it leaving and changing in both vagcom and

xp device manager but stil says interface not found.

Might have to risk another ebay cable

thanks baz

had this a few times with vw.

1)is the ignition switched on

2)have to done the "options" screen and test usb port

3) sometimes just restarting again (ie shut down laptop, remove cable, start car and stop it) can kick it up again

[wilkinsonbaz]

hi thanks for reply

yes ignition switched on

done the options screen and com port changes when tested port ok but just wont see interface

have restarted tried different laptops and just bought another ebay cable with drivers from a seller thats sold 8482 cables so they must work but

getting just same results! and just put a fresh copy of windows xp on the laptop i used so it shouldnt have any conflict with past drivers or vcds lite programs etc but same results port ok interface not found grrr!!

i think it must be the car or socket so am going see if i can find wiring diagram for socket and have a look at the weekend

thanks baz

Just a thought but could you try the existing setup on another car?

 

I'd guess most VW's the same fuel/age should work...

[chrispb123456]

You could ask for a member in your area to try your set up and vice versa on their car, I think I'm to far away but would gladly do this if you were local ish (North west Kent)

hi thanks for replys

a neighbours got an 02 seat leon tdi so im going to give it a try over weekend

ive been reading on tdi forums and ross tech about checking the pin outputs especially the k line

and watching out for non original stereos that been fitted and problems with vagcom

i also read on a forum that if the abs light is on which mine is the abs module sometimes causes problems with vag com

this was vw's but guess it could easily be the same with galaxy's

its just frustrating it was working fine before, but will post my results it might help someone else

regards baz

hi folks

at last ive got the vagcom working

it was the 12v supply mising on pin16 there must be a break in the wire somewhere,

the fuse is intact had already checked it before

the vag com cable even though it had the led lit might have been getting that from the usb supply

anyway its working a treat abs is rh front not sensing so can sort that out

so anyone getting similar problems check the socket wiring you only have pin4 and 5 ground, pin7 kline or diagnostc feed and the 12v supply on pin16

you can find more info at http://www.ross-tech.com/vag-com/aftermarket-radio.html

it also gives you info of how to test the pins,

easy cure after all that, kicking myself for not checking wiring earlier but with it working fine before didnt think it would be the problem!

anyway anyone in otley west yorks wanting a vagcom cable for price of a pint let me know i now have 3

 

one other thing i checked was the turbo pressure as in one of my other posts i had limp home mode and cured it

with innotec turbo cleaner

the actual pressure with foot to floor is running about 150 over requested but still no limp home yet

its been about a year since i cleaned turbo so going to run some more innotec through turbo when i service engine later in month

phew,1 happy camper now.:blink:

[alan_131]

Glad you got it sorted. I've just checked and my cable has the led lit whenever it's plugged into the car, even without the laptop or the ignition being on. Can't tell if this is driven by the 12v or the data line. It would be nice to know if most cables worked the same, so I was wondering if you thought that the led on these cables was a good indicator for the 12v being present or if it varies by cable type?

[wilkinsonbaz]

hi mine is mk1 99t tdi so others might vary especially if its petrol engined

but the 12v on pin 16 is a permanent 12v fed from fuse19 the one for central locking etc

the kline feed on pin7 on mine read 10v ign on 11v ign off, now the ross tech info tells you to check the kline feed by putting a 1k ohm

resistor across pins 7 and 4 and check the voltage when i did that makes my digital voltmeter vary quickly from 2 to max 10 volts so presume its pulsing sending a signal to communicate with the cable because of the resistor

as for the led when its plugged into to a laptop the led is lit but now i have the 12v on pin 16 its brighter

without the laptop connected and the fuse pulled out there is no light on cable, thats the bit i missed checking.

now i have 3 cables all do the same no 12v pin16 no litey ign on or not, then led on but bit dim when hooked to laptop.

so can be a quick checked for anyone with similar problems plug cable in make sure the lights on before hooking to laptop
