Vista Compatable?

[A4Ade]

If you're still having problems, I use 409 with Vista - never used XP (or any other) compatibility mode, but DO have to "Run as Administrator". Works fine then for me...

Ok remembered I still had this cable and with current ABS and ESP light issues thought it best to get it out and try again. Got it set to COM3 and run a test, it comes back saying Passthru test ok.

So select AutoScan, select Audi TT in chasis and press Start, all addresses are looked at in turn but nothing actually comes back, get timing counters thats all.

If it works then I assume you a list of the results come up straight away in the right hand screen? On mine nothing comes back?

Am I doing something totally wrong or is the VAGCOM test telling me lies and my cable is faulty?

A couple of things I can think of off the top of my head:

1) Is your ignition on?
2) If you a re choosing COM3 have you checked that the cable is on COM3 in Device Manager?
3) Is your VagCom licensed (paid for)? If not, Autoscan wont work - you have to scan the modules individually (even my fully licensed VagCom wont Autoscan some cars for some reason - will do an A4, wont do an S3, for example).
4) If you have Vista, have you run VagCom "as an administrator"?

Thanks for the tips.

Thinking no.3 is odds on to being the most appropiate answer in this case.

What cable do you have?

On the B6 A4 all of the module diagnostic connections are on the K-line (on the B7 some are on the K-line and some on the CAN bus), but the 8P A3/S3 don't have a K-line so all diagnostics is via CAN bus - so if you don't have either a HEX-COM+CAN or HEX-USB+CAN cable then your cable won't work on an 8P.

Thanks, I'm know my (3rd party) cable wont work with CAN bus cars, but the S3 in question is an 8L which (I think) should be fine - I can certainly scan the modules individually no problem. Only on trying an AutoScan does VagCom crash, yet on my A4 it Autoscans fine.

It should.

Since you only said S3 I thought it worth mentioning the CAN bus issue.

No idea why you can autoscan on an A4 but not an 8L S3 ....

What version of VAG-COM are you using?

Have you reported the problem to Ross-Tech? If you're a registered user they will help all they can.
