VVDI2 MED9.1 ECU Adaptation, How to?

Car: It’s a 2013, Scirocco R.

Purpose: I want to adapt a used MED9.1 ECU in another car (Scirocco engine change, want to change the VIN and the CS of the ECU) with Xhorse VVDI2.

I have the IMMO of the old ECU + Cluster and all IMMO Data of the Scirocco where I want to put it into.


First you need to read CS and pin form this used ECU, Hit Automatic detect.

When read that , hit “Read” at top screen.

Then when screen comes On, you put old CS , VIn and pin and hit Write.

VVDI2 vs Obdstar tools MQB odometer correction

There are two options of MQB dashboard odometer correction: Xhorse VVDI2 and Obdstar tools (Obdstar X300M, H110 or key master, etc.)

So, how to chose and which one is better?

In details…

Both the Xhorse and Obdstar tools are confirmed to work no issues for VAG MQB.

VVDI2 VAG MQB Immobilizer & dashboard: confirmed!

VVDI2 now supports part of VAG vehicles only.

Check the list here:

Audi A3/S3 2014+, Audi Q2

VW Golf7, VW Polo(MQB), VW Tiguan II, VW Touran II, VW crafter 2017+, VW Passat B8 without virtual cockpit

Skoda Octavia III 2014.07+, Skoda Rapid 2015.06+, Skoda Kodiaq, Skoda Superb III

Seat Ibiza/Ateca/Toledo 2015.06+

Note 1: This type only supports cars with cluster Continental/VDO. JCI type and virtual cockpit is not included

Note 2: MQB Immobilizer function supports original blank key and MQB key made by VVDI2

Note 3: Part of original blank key not support write data

Note 4: MQB Immobilizer function require extra license. Customers who have copy 48 (96 bit) license will get MQB license for free


Obdstar H110 VAG MQB dashboard: confirmed!

Obdstar X300M VAG MQB dashboard: confirmed!

Obdstar key master VAG MQB dashboard: confirmed!

But, theyre kind of different, esp in price, function and car list as well..


Xhorse is much more expensive than Obdstar tools but Xhose supports MQB immo and dash while Obdstar supports dash only.


Note that Xhorse VVDI2 is the only key programmer can be used for VAG MQB platform instrument immobiliser. Instrument with NEC35XX (Continental/VDO)


Xhorse VVDI2 works perfect in BMW and VAG key programming.

Have it if BMW key programming is required.

If not, go for Obdstar tools – cheaper but working good, support more MQB types


If you need a tool for VAG immo and dashboard, go for Obdstar H110;

If you need a universal odometer correction tool, go for Obdstar X300M;

If you works for a workshop, go for Obdstar key master and you’ll never look back.


Ps. Obdstar X300M and H110, at the same price, depends on your need.
