Xhorse VVDI2 vs VVDI Key Tool Plus VAG Version

 Question:

I’m stuck between vvdi2 full VAG version SV86-C+XNR-SS290 and VVDi2 Keytool plus VAG version xDKP02GL, I am already purchasing VVDI multi prog so I need a tool that will greatly help in vag immobilizer & instrument cluster cloning,key learning etc and not for diagnostics.

First of all, check a table comparison below:

Item	Xhorse VVDI2 Full VAG	Xhorse VVDI Key Tool Plus VAG
Basic VAG IMMO/KM correction	Yes	Yes
IMMO4	Yes	Yes
IMMO5	Yes	Yes
Porsche IMMO	Yes	Yes
OBD48 Clone (obdii copy 48)	Yes	Yes
96 bit copy 48	Yes	Yes
MQB/49 (5C) IMMO System	Yes	Yes
IMMO Data Tool	Yes	Yes
MQB48 License	Need to buy MQB48 License	Need to buy MQB48 license
MQB48 RH850	No	Yes, with RH850/V850 cable
IMMO for other brands	No	Also work on other ordinary brands such as Toyota, Honda, Ford, Buick, Chevrolet, etc.
Toyota 8A All keys lost	No	Yes
Key Tool Functions (remote clone, transponder clone, generate remote/transponder, Remote cloud recognition)	No	Yes
Remote renew	No	Yes
Maintenance feature	No	Yes
Control xhorse key cutting machine	No	Yes

In sum:

VAG function is almost the same expert key tool plus supports RH850 MQB48 immo key programming, vvdi2 does not.

Key tool plus has PROG function to read eeprom, ecu and mcu. Vvdi2 does not.

Key tool plus has key tool functions, it can generate remote/transponder, clone remote, renew remote etc. VVDI2 does not.

Key tool plus have extra immo coverage for some common brands, Toyota, Nissan, Ford, GM etc, it also does Toyota 8A (smart and non-smart) all keys lost. Vvdi2 does not.

Key tool plus also controls key cutting machines. Vvdi2 does not.

Vvdi2 full vag version price is the same as full version. Vvdi2 full is recommended.

How to Fix VVDI2 Cannot Read Kline VW Polo Golf4

 Here comes the DIY solution to xhorse vvdi2 unable to read VW K-line dash problem.

Unable to read k-line polo, golf4 VDO dash but able to read Sharan k-line edc15 ECU but unable to learn keys to the very same car (can’t connect to immobox or similar error).  Took apart but there is no burnings.

It was id44. Separated immobox behind the odo with edc15. Pin from ecu, precode 7935 to VAG id44 and learn thru channel 25.

DIY Solution:

The vvdi2 is working again. Here is the solution

After disassembled the vvdi you MUST be extremely careful with the big yellow backup battery pins!! If you connect them the DALLAS (security chip) will be deleted immediately and you have to send back to china to reprogramming. There is no other way to repair!!! YOU HAVE BEEN WARNED!!!

1: Remove the cable from the vvdi and check the connection with multimeter. This two pins on the first picture must be connected

2: Disassembly the vvdi2 vag and attach the cable to the vvdi and check with multimeter the connection between the obd plug pin #7 and the marked pin on the pic

3: There is a MOSFET relay which is switching the port. Check for burning marks Here is the datasheet

4: On the third picture there is a multiplexer. Because only one kline driver working in the vvdi2 if any other pin using the kline somehow able to switch to pins. This multiplexer doing this. Here is the datasheet Mosfet pin #4 connected to ADC1606 pin #22

5: UART to Kline bus driver. This device is “translate” between the car kline network and the vvdi2 MCU. Here is the datasheet ADC1606 pin #28 connected to KLine driver pin #6

You can’t really test the switching components. The only sure way when you replace them. You can replace the mosfet from any other neighboring one, but the multiplexer isn’t available for me thus i skipped that part. Instead of i replaced the Kline bus driver, after the change my vvdi is able to communicate on kline again.
Hope it helps.

VVDI2 Program VW Passat CC 2010 ID48 All Keys Lost

 It’s a 2010 Volkswagen Passat cc all key lost.  id48 315mhz.

First you read CCM was used CG Pro programmer

Get CS PIN from vvdi2 vag via dump

Then prepare key with key tool plus

After reading 95320 data with cgprog and saving the file, get a cs pin code from vvdi2 as a dump file, create a dealer key with vvdi key tool plus and register the key, run remote control.

You can also make an XT27 on used position and just start the car no need any operation on OBD just learn the remote.

Xhorse VVDI2 Adds 2000 VW Beelte Key by Super Chip

 These old beetles can be a real pain to do. This is a 2000 VW Beetle, Xhorse VVDI2 VAG read EEPROM via OBDII, clone out key to VVDI super chip XT27. The procedure is the same to 1998 to 2007 VW Beetle with Megamos 48 transponder.

Go to Special Function– K-line Instrument/Immo Box, Read EEPROM via OBD

Go to Immobilizer data tool,  make dealer key by eeprom

Xhorse VVDI2 Write VW Eurovan 24C04 Key via Dump

 2002 VW Eurovan does anybody have instruction on how to add a key (ID44 transponder) with xhorse vvdi2 vag?

Solution:

Remove immobilizer behind left side of the instrument cluster, remove EEPROM 24c04, read with vvdi prog programmer, load into vvdi2 key by file and program a new chip or clone an existing key position with a vvdi super chip xt27.
