The procedure can be applied to Kessy including kessy continental 93C86 all keys lost,
Suits
Audi A8
Porsche Cayenne
VW Touareg
VW Phaeton
Bentley Continental
Are all id46 chip.
The job is done by xhorse vvdi prog and vvdi2.
Here we take an example of the Porsche Cayenne Kessy ID46 key.
Remove kessy module, read 93C86 eeprom with vvdi prog
Better solder following the wiring diagram

With Xhorse Vvdi2 go under VW immo4 you will see A8 last option (Immo Kessy- Audi A8, VW Touareg, VW Phaeton, Porsche Cayenne, Bentley Continental 93C86) load the eeprom file you will get the CS and the pin.
Get pin. Program virgin key with login pin with vvdi2.
Make a dealer remote and connect the Vvdi2 to the car and learn the key (only if your chip is ID46).
If you try to open to get cs says unknown version. You should desolder and read again. Always de solder it just because the crystal.
Question: I am working on 08′ Audi A8 keyed ignition. Can I simply read with VVDI Prog and clone out/write/make dealer key with vvdi2, or do I need to write file back with the key?
Tips to make key Audi A8 2008 with vvdi2:
2018 VW Passat MQB48 keyless and Passat b8 2015 johnson controls – all add key failed using Xhorse VVDI2 VAG.
It’s saying not supported.
Got to Mqb part
It pulls dash model etc
But when read. Immo data says not supported
Autel failed as well. Possible add key other way?
Solution:
No aftermarket device can do Johnson Controls and also virtual cockpit out of the box.
Need calculate data (sync file) online. Vag helper doesn’t work anymore server is down.
Is there a way to read it immo data?
To program VW Audi 5th IMMO keys like A4, A5, Q5, A6L, A8L, Touareg, Xhorse BCM2 Solder Free Adapter would help a lot. Users can easily select the corresponding method on VVDI Key Tool Plus to work with it.
There are mainly 2 types of car models in programming Audi 5th keys:
This type of models only need to get immo data for key adding & all keys lost. The representative models are A4, A5, Q5.
Ways to get immo data:
Note: Data read by Xhorse BCM2 Adapter is only used for key programming, no support BCM clone maintenance.
Suppose that you don’t have the Audi BCM2 Adapter when all keys lost, you may have to pay an additional cost $170-$500 for data calculation via OBD. With the adapter, all these are free.
This type of models need to get immo data & synchronous data simultaneously. The representative models are A6, A8, Touareg.
For key adding situation, either VVDI2 or VVDI Key Tool Plus can get immo data by OBD regardless of years. Users can get synchronous data from a working key without having to read BCM. It’s very relatively simple.
For all keys lost situation, certain CVT gearbox of vehicles before 2012 support to read BCM data via VVDI PROG. Then users can follow steps on VVDI2 or Key Tool Plus Pad to online calculate synchronous data.
(*Few cars are workable in this way, it requires experienced locksmith to read directional lock and engine data, short circuit communication line. It’s not recommended to do without experience.)
As for vehicles after 2012, those BCM are generally locked. At this time, the Audi BCM2 Solder-Free Adapter can help to read out data. After that, users should convert immo data via VVDI2 or VVDI Key Tool Plus. If it allows to read directional lock and engine data again, which means it supports to get synchronous data for all key lost programming. If not, users should find third-party calculation.
Price Difference
Conclusion
It’s recommended to have Xhorse BCM2 Solder Free Adapter for locksmiths who usually program VW/Audi 5th immobilizer system keys. The adapter not only greatly save cost, but also earn more for next time job. It will pay for itself once using it.

Car model: Mini Cooper 2012
CAS Type: CAS3++ ISTAP
Remote frequency: 315MHZ
Status: all keys lost
Procedure:
Update CAS flash
Read key info
Prepare key success
Make dealer key success
For cas3 istap , it can do by obd2 for some part number of CAS , you can see list on instructions PDF of vvdi2, out of list if you do by obd2 it will fail if you have best tools you can fix it by obd2 too (HEXTAG, AUTEL, VVDI2 etc).
Always make a backup first and have a battery maintainer under the charger. Otherwise will brick car.
The safest way is done on bench.
