VAG-COM Scanner by Ross-Tech & VCDS Software (2021 Diagnostics Cable Tool)

Own an Audi, Volkswagen, Skoda, Seat or Bentley car made between Jan 1994 to ? Then Ross-Tech VCDS® Software and VAG-COM Diagnostic scanner will help you diagnose all modules for any kind of possible problems.

Features you'll have access to are equal to dealer level factory tools. What's more, the included original VCDS software surpasses the performance of aftermarket diagnostic tools and alternative factory tools found throughout Amazon, which all came AFTER RossTech's scanner.

Therefore you'll always know precisely how the vehicle is functioning and what is most effective way to fix it. Meaning this kit is suitable for both home car owners and professional workshop mechanics.

Besides thoroughly scanning car module data and health, but the software can also modify vehicles performance and behavior on how it functions inside and performs outside on the road. Meaning you get to customize your car to your personal liking.

For example — besides just reading and/or clearing generic and manufacture DTC (Diagnostic Trouble Codes) fault codes — VAGCOM can also perform: adaptions, mileage adjustment, behavior of components, testing components, brake bleed, DPF, EGR, etc.

Basically you're getting same advanced level diagnostics and coding support as OEM dealers or a certified VAG mechanics have — who charges upwards of $250+ per hour.

In addition — this VAGCOM kit also works as generic OBD2 reader on any car brand in the world (EG: BMW, Mercedes, Subaru, Nissan, Toyota, Mazda, GM, Ford, etc).

In short — it's capable of extracting, diagnosing and resetting 4,000+ (OBD2) Engine/Transmission fault codes on non-VAG vehicles.

And 25,000+ (OBD1/OBD2) generic and manufacturer fault codes on VAG vehicles (Audi, Seat, Skoda, Volkswagen, Bentley).

And before mentioning functions, let's first remove any misunderstandings...

Difference Between Total Car Diagnostics VAG-COM and Original  Ross-Tech ™:

Firstly, this is not the original RossTech kit as sold for $600+ on their website...

Our cable uses a 3rd Party manufactured chip. That's why we can keep costs down — because we're not using Ross-Tech™ OEM chip — but 3rd party chip using identical firmware code.

In short, this cuts down our OEM licensing fees... hence we pass those savings onto you.

It also comes with original license-activated VCDS software, which works on unlimited car VIN's and computers. And has ZERO restrictions in functionality compared to original. (Software is NOT cracked or modified in any way.)

Lastly, this HEX V2 cable has no connection to the cheap VAGCOM clones found aplenty on eBay/Amazon, which basically all use VCDSLoader.exe crack, which invalidates 50% of software functionality.

Disclaimer: We are not associated to RossTech company. All technical help for this product must go to Total Car Diagnostics. Our hope is you'll see how good our cable is and eventually buy the original Ross-Tech, because they absolutely deserve it and are always up to date.

 

Ross-Tech VCDS & HEX V2 will give you ability to:

• Gain factory level information to all modules in most Volkswagen, Audi, Seat, Skoda and Bentley models from 1990 through the current year.
• Scan and erase diagnostic-trouble-codes with 25,000+ fault codes.
• Modify functionality of various modules through coding. Gives you same power as VAG companies towards their own cars. For example: remove seat belt chime, enable gauge test/needle sweep, enable lap timer, operate windows and sunroof with remote, etc...
• Monitor and save live data.
• Reset service reminder / oil reset.
• Perform built in tests and calibrations.
• Diagnose problems to save you money from swapping parts.

 

Now let's look into the specifics...

Make no mistake, our VAGCOM USB cable cable will give original VCDS 20.4.0 full version software with all features unlocked... and without any "hidden" future payments. Basically it's unlocked to full version for a lifetime.

There's no monthly/yearly fees of any kind.

This means you can access to all manufacturer codes on your vehicle(s) like: ABS, Airbag, Air-Condition, Windows, Lights, Tires, Immobalizer, Electronics, Engine, Transmission, Radio, etc.  ^{(See screenshots for more info)}

Testing the ABS...

This presentation shows VAGCOM used on a vehicle to detect a problem with it's ABS system. Different tests and procedures are shown...

• It shows you process to reading fault codes and saving the displayed DTC code to a file.
• Code is cleared and after re-checking is found to have immediately re-instated. This shows us that the fault is present on the car still, so further testing is shown.
• Next the video shows how the output from each wheel speed sensor is measured and shows by VCDS software as the car is driven a short distance by testing assistant.
• Speed signal from each irrespective sensor is displayed in the measuring blocks and the output is seen to count up from 0k/ph to about 10k/ph on 3 wheels while one wheel remained at 0k/ph.
• Output is also displayed using the VAG-Scope tool which is included in the VCDS software. This shows how wheel speeds can be recorded and viewed after a short drive - when there is no assistant available to operate the vehicle.
• ABS pump, brake pedal switch and modulator valve block are tested thoroughly using the output tests.

• A fault code is detected and stored in the TCU and the code number together with the text meaning for the DTC fault code is shown.
• Additional information displayed by VCDS software shows the error code is intermittent
• Live data segment of VCDS software reveals the values from the throttle sensor and gear selector switch.
• Extra live data screen reveals each gear solenoid and teaches you what each does in relation to gear changes and driving mode.
• Live data is presented at various on-road speeds and status for each solenoid is shown.
• Difference between mechanical drive and hydraulic drive is clearly depicted and clarified.
