It’s a VVDI2 VAG manual of CS, PIN, MAC reading. Manually read cs, pin and mac from vag 4th immobilizer system ECU and automatically from vag 5th immobilizer system ECU

You can select autodetect engine control unit existing to get PIN/CS or type in known

PIN/CS manually

Component security bytes. It has 12 bytes for UDS 4th immobilizer cluster. Move your mouse to this area, you will get balloon show 7 bytes CS in ECU show original 6 byes CS is: C2 D3 45 7E 68 0E). You can’t find 7th byte CS from UDS 4th immobilizer cluster, it don’t have 7th byte, it have another 6 bytes CS part 2

CAN 4th immobilizer cluster (CDC32xx, A3/TT/R8) will have 7 bytes at this value. That

is the original 7 bytes CS

ECU must have same 6 bytes CS with balloon show CS bytes. If they are not same,

you car can’t start

login code, it can use login to ECU or other module which support login immobilizer PIN. You can learn dealer key with CAN protocol cluster ECU has same PIN with this value. If not same, car will not start. So, for CAN protocol cluster, you can learn key with PIN read from ECU

Synchronization codes between ECU and immobilizer system, usually have 4 bytes. The first 2 bytes is immobilizer synchronization code, the last 2 bytes is ECU synchronization code. MAC value in the picture above is “B188708F”, “B188” is immobilizer synchronization code, “798F” is ECU synchronization code. Generally, the synchronization code for ECU or immobilizer system is a fixed value. If you install new ECU, MAC value in immobilizer will change last 2 bytes to new ECU synchronization code; if you install new immobilizer, MAC value in ECU will change first 2 bytes to new immobilizer synchronization code. 

Normally, MAC value must be same between ECU and immobilizer. If there are not same, ECU and immobilizer system will have same DTC error like this: Engine control unit is not authorized. You can fix this error by “Adapt Unit->select ECU->Read->Write”, it willsynchronize MAC automatically between ECU and immobilizer system

Autodetect PIN/CS:

Read PIN and CS from engine control unit or immobilizer system automatically. After success read PIN and CS, you just need input key count to learn key

NOTE: PIN, CS, MAC function only can be authorized for free for those with Xhorse iKeycutter Condor XC-MINI key cutting machine.

Here is a tutorial for using KTAG K-TAG ECU Programming Tool Master to read VAG Audi A3 ECU EDC17C46 on bench. Steps are as follows:

Step1. Open Audi A3 ECU EDC17C46 unit: first heat the edge to soften glue inside then open it carefully not to damage the circuit board.

Step2. Open KATG K-TAG software. Connect the cable 14P600KT02 to ECU connector according to following pin out diagram:

Step3. Take a wire, cut the wire cover at the middle. Solder its two ends to the two pins (red) as follow:

Step4. Back to K-TAG software, choose plug-in “P199” and click “OK”.

Click “Read” and wait it 100% complete. And then save the bin file. Now KTAG ECU Programming Tool read VAG Audi A3 ECU EDC17C46 successfully!

Have managed to use Xhorse VVDI2 VAG commander for 2016 new vag all key lost. Report it here.

Ecu type:

Me17.5.22

????1-11

Note:

Johnson control with 95320 - uds

Generally, this type instrument use 95320 EEPROM.

There are two methods NEC+95320(Johnson control), NEC+95320(jci 2013 bora/jetta)

There’s a special procedure for prepare dealer key:

Menu->key learn->4th immobilizer system - VW/ skoda/ seat (choose the specific type according to the car)

This function will read PIN/CS from ECU or (input PIN/CS) and prepare dealer key. The dealer key can learn to car

After running this function, it changed 6 bytes of all 12 bytes CS in immobilizer system. So the old key cannot be used anymore, and don’t accept any key come from dealer

Here are some tips for OBDSTAR VAG PRO”license error” when change mileages, reset service and steer on Audi.

2007 gti,  2008 seat leon, 2008 audi a4? 2012 audi q5 fails to do steering reset, mileage correction, service reset. And the device displays “license error” then the dashboard is freezed.
