I have a 2003 Jetta it was a gas 1.8 now alh . Starts and runs but can not check timing. I can read codes with vagcom with key on but when I start engine it goes to too many communication errors to continue. Timing and I are out of adjustment. Everything else in car works fine
Help please

What version of VCDS are you using?
What does all of the writing on the interface say?

I'll check tomorrow. VCDS works on all the other cars I've worked on

Its a 11.11.5 version. I can read and auto scan codes with engine off, once started them too many comun. errors.
did a autoscan codes 17970 16612 17654 17762 00849 01064 00625 01330 01336 01299 01314 01177 00771

11.11.5, way out of date. Lets first try a fresh install with the current version. Here is our web page to download the latest version:

http://www.ross-tech.com/vcds/download/current.php

Once you get the current version, let us know if it helps. If not, we'll see about getting a debug report from the current version of VCDS, that might yield some clues.

One other point: What computer and what operating system are you using? Is this the same computer you have used before with VCDS? I have heard of multiple communications problems with newer laptop and tablet computers with Windows 10 relating to the computers power management. Look into power management and look at the advanced settings and look for power settings related to USB. Computers trying to reduce power usage (save batteries) can cause VCDS communications issues if they try to cut USB power.

Have Fun!

The computer is an old Dell with XP. It works fine on all other cars, not this one. Swapped ECU no change.

Running on batteries or ? I seem to recall someone having flaky comm running, iirc, power to the laptop from the car or some such . . . If not running fromthe laptop battery, it might be worth a try . . .

Please post the debug logs you're getting with your *current* version of VCDS... the version that's giving you all the communication errors.

Otherwise everyone's just batting at smoke. :) :)

I'd still like you to answer my question regarding power source for the laptop . . .

Looking at the logs could fix your issues permanently... what's the issue?

Not sure how to load the logs on here. Which ones would be helpful?

Jef can suggest any specific logs he had in mind, I was thinking start with the line-by-line readout you get doing an autoscan.

Cut-n-paste to here will work fine, and probably best to <S>ave the scan to a file on your computer and then cut from that file... if you just try to grab it off the screen as it scrolls by something might get missed.

An autoscan might help but I am not sure. It couldn't hurt to post it.

However, I doubt that much more help will be coming from Jef. The latest versions of VCDS require a firmware update for the interface cable itself. If the OP's interface won't accept the connection from the latest version, it is probably not a genuine Ross-Tech interface cable (or else he has Windows USB issues or a faulty cable). If I am correct and it is not a genuine R-T interface cable, I would not expect much help from R-T support people. If the problem is with a Chineseum interface cable, support will have to come from the thieves who sold him the cable (and cracked software version 11.11.5) in the first place.

Have Fun!

Ah, but posting the auto scan will clear up the providence of the interface once and for all. :) And, if it's an off-shore clone that in itself is likely a strong possibility as to the comm issues and potentially diminished returns to troubleshoot deeper.

I don't think the problem is with VCDS, since it works fine with 10 others cars. What I need most is to be able to set timing and IQ.

Well, you need a functioning interface to talk to the ECU to read the timing and set the IQ., and not to put too fine a point to it... but I think it boils down to:

- if it's a genuine interface...that's one possibility eliminated (ie it's not flaky offshore hardware with cracked firmware/software, that's struggling a bit in an engine swap situation) and a bunch of folks here will likely be happy to help further

- if it's a cloned interface with pirated software...that could be the problem in and off itself, and as this forum does not condone piracy any further discussions to further troubleshoot are best taken up with the seller of the hardware/software, as posted above.

Not saying one or the other is the case... just pointing out that the road forks at this point. :)

I have a friend that has a commercial VCDS. Maybe he will let me borrow it over the weekend

Let start with this, on the interface, the part you plug up to the car is a sticker. What is the information on that sticker? A photo would be fine.

It would be correct to assume that we (Ross-Tech) are not inclined to invest any effort for some one who is using a clone product.

With some of your statements provided, I have my doubts you are using a legitimate Ross-Tech interface. But before any one passes final judgement, I think it is fair to ask for some proof to show you have the real deal.

I bought the cable and program from someone either here or Vwvotex
Not knowing or care what its origin as long as it worked. Been using it for 5 years.
Like I said I'll try my friends original business quality

Yes, but Jef is saying if it's an authentic cable, he'll provide some support

OK tried the official Ross-Tech cable with the current program. Same too many communication errors.
