3.At the principal menu press F3-tool solutions.

4.In the tool alternatives screen pick F9, CANdi Diagnostics.

5.You will find two tests on the subsequent screen, run them each. When you get pass on each, that you are excellent to go. The CANdi should really talk to your 2004 vehicle.

6.Either turn the ignition key of your car to on, or start out it (for a C6 there is not an "on”).

7.Press the EXIT button till the Tech2 Scanner goes back to the primary menu.

8.Choose F0, Diagnostics.

9.Make all of the requested selections to get you for the module inside the automobile you would like to appear at.

Xhorse VVDI2 or Flyobd FVDI2 (not FVDI 1st generation but 2nd)? I am gonna buy one of these, just don’t know which one would suite me best. I’ll use it for VAG group clusters changing g6/touran/tiguan etc., immo adaptation, making keys, millage correction. Any advice?

VVDI2 VAG vs FVDI2 VAG:

VVDI2 VAG supports VAG cars: VW, Audi, Seat, Skoda, 4th immobilizer Porsche, 4th immobilizer Bentley.

It works perfect in diagnostic, 4th immobilizer, 5th immobilizer, key learn, BCM remote control, Engine control unit, Kline instrument and immobox, adapt unit, component protection, dump tool etc

FVDI2 VAG supports VAG cars: VW, Audi, Seat, Skoda VAG-VW, Audi, Seat, Skoda 4th & 5th immobilizer,incl. 4th & 5th immobilizer AUDI A6/Q7, 4th immobilizer Porsche, 4th immobilizer Bentley.

Also, it works good in basic diagnostic, key programming/PIN codes reading, mileage correction, fault codes reading

VAG diagnostic:

VAG key programming:

Special functions for VAG:

From the charts above, FVDI2 FLY and VVDI2 Xhorse almost share the same functions.

They mainly differ in these aspects:

1 OBD read CS/PIN of MED17

2 generate OEM remote control

3 software authorization

FVDI 2 Commanderfull kit includes software for VAG – VW, Audi, Seat, Skoda; Porsche; Mercedes/Smart/Maybach; OPEL/VAUXHALL; BMW; Peugeot/Citroen; Fiat/Alfa/Lancia; Renault; Toyota/Lexus; Hyundai/KIA; Nissan/Infiniti; TAG Key Tool; Ford; Volvo;Chrysler, Dodge and Jeep; Mitsubishi; DAF; Bikes, Snowmobiles and Water scooters.

VVDI2 full kit includes VK-01 Transponder Programmer, VJ-01 Passthru J2534 and software for VAG – VW, Audi, Seat, Skoda; BMW; PSA (Peugeot/Citroen); Porsche

So, If you looking only for VAG + BMW , then VVDI2 and VVDI Prog is way to go. No need any other tool. In VVDI2 you have also programmer similar to Tango that you can make keys buy dump, but 90% of VAG and BMW can be done by OBD in VVDI2.

VVDI programmer don’t have OBD it’s only for bench programming.

Good for CAS4, FRM, EZS, EWS4 and many more.
