I understand that VCDS from Ross Tech is the official VAG diagnostic software, but what is the difference between it and say ScanTool.net for example. I can see the latter only monitors engine sensors, and cannot re-programme any settings; and can only give an instant read out and not record logs etc. Are there other reasons for using VCDS; accuracy of DTC reading and diagnosis for example? I guess what I want to know is what is the benefit of spending £200 instead of £40 or so.

First, you probably will not want to hear from me since I have a vested interest in telling why VCDS is a complete solution versus the partial solutions offered by others.  But having said that, let me also state that VCDS is not the answer for all.  If you are going to use it once to make some mods and then throw it in the tool box and not drag it out again, it is a waste of money in my opinion.  However, if you are interested in DIY repair and you are looking for a complete solution, you should consider VCDS.

One of the questions to ask is how many fault codes are decoded in the tool?  VCDS now has over 16,000 fault codes decoded and put into language that may give a clue what is wrong with the car.

Next, does the tool give you the additional information along with a fault code - does it provide freeze frame data in modules that support freeze frame data.

Does the tool provide access to all live measuring values?

Does the tool let you perform Basic Settings, Adaptations and Output tests required to repair systems in the car?

Does the tool let you code modules and does it provide an easy to use Long Coding Helper to assist you as you make coding changes?

Does the tool manufacturer have a support function on the web that is free to use by anyone?

If you get stuck and need help, does the tool manufacture have a tech support function you can contact to get help and is that function staffed by professionals who were trained by VW or Audi?

The answer on the VCDS side of the equation is yes to all of these.

Good luck with your search.

Thanks, appreciate your reply. In truth I simply want to be able to read a dtc and monitor engine and related sensors, nothing more. I have no desire to do any diy, nor vehicle recoding. Vcds is simply too sophisticated / costly for my needs, otherwise I'd just take it to a dyno. If there is an obvious fault then I'd simply take it to a garage.

I have always carried out my own servicing and repairs including stripping an engine and installing a short block at the roadside (long time ago). I also tend to be the person at work others expect to be able to sort any PC problems, when my children were small I used to write short programs for their Sinclair Spectrum.
If I were to buy VCDS how easy is it to learn to use it? Does it come with a manual or does a new owner need to find a "wise old elder" or probably in my case a "wise younger"
I intend to keep my Yeti for a few years and would be happy to help others if I were able to do so.

Well considering you have a mechanical and software understanding I would not think it would pose any issues to you at all.

ALWAYS save a scan before you do anything, this will save the current codes the car has, not to mention pinpointing any current fault codes you have.

Then it's time to read up on the 'net on what can be done and how to do it, once you understand the way VCDS works it's pretty straightforward.

  As Gizmo stated, the product is pretty easy to learn and if you know VAG lingo, you should have no problem adapting.

As to a manual, you can print one out at any time or you can go to our web site and use the online manual/demo.  The buttons on this online manual are active and the description of the contents of the screen is given below the screen.

When you need tecnical information, you can check the Ross-Tech Wiki.  Granted, we focus on more US models, there are many similarities to the UK models.

And for registered users, there is free tech support by our staff via email.

Thanks for the speedy replies,
I have had a quick look at the Ross Tech site and will spend a bit more time looking at it later in the week. From first impressions I think it is highly likely that I will make a purchase. From the short time I have spent on the website it looks like the Yeti needs the Micro-can which covers models based on Golf technology. I see Gizmo has VCDS Hex+CAN listed as covering all VAG cars, and on the Ross-Tech website the Micro-can is described as an enthusiasts tool which gives the impression of being limited/less able. So a bit more reading and being nice to SWMBO is called for.

Any more advice/comments would be appreciated.

[Gizmo68]

If you are only going to do your Yeti then the Micro-CAN interface will be adequate, however they can not do (older) non CAN based cars (Fabia, MKI Superb MKI Octavia, MK4 Golf, Polo etc).

IMO the extra cost of the HEX+CAN interface is worth it...... but only if you will use it on these cars.

[The Hood]

I've been looking at the Ross Tech site and have downloaded the manual (but not bought lead yet), This may seem a silly question but where is the diagnostic socket on the Yeti? I could find it on a couple of VW's but not for the Yeti.

[Gizmo68]

Just up from the throttle pedal.
(which is where it is on all newer VAG vehicles)

Simply  VCDS > other software, unless you somehow can get hold of the VAS stuff the dealers use.  Personally I love VCDS.  Very intuitive and does loads.  Today I checked timing on a 2.5 V6 engine, and was able to advise on retarding the engine to get it in spec.  Never knew it did timing checks on non PD engines.  Top function!

Hi Gizmo68
Found it!
Thanks once again for your help

[The Hood]

Just ordered VCDS HEX+CAN from Gendan. Thanks Gizmo68 and Bearthebruce for your help and advice. Roll on Monday

I will make sure that I take and save some scans before attempting to change anything. What I would like to do initialy is change the maxidot to MPH, change the leave/return home from the xenons to the foglights, and stiffen up the brakes as I find them a bit soft after my last car.

One of my brother in laws has an Audi and the other a golf so hopefully we could all benifit eventually.

VCDS Hex-Can arrived this morning. Loaded tested and working O.K. first scan taken and saved.

Before I start to change anything I will have a good read through the Ross-Tech on-line manual. I will also have a look through Briskoda in cas there is a section which is of help to those of us starting out.

Thanks again  Gizmo68 and Bearthebruce.
