Read Skoda Kodiaq 2020 MQB Dash with Xhorse Multi Prog

 A 2020 Skoda Kodiaq arrived with one key. The task is to make an additional key and a chip for auto start.

In order to make a key, we need to get data from the dashboard. All Skoda Kodiaq cars use the MQB platform and has a protected Renesas RH850 processor, which is where the main difficulty lies.

The process of preparing for reading and reading the data itself is quite painstaking. It is necessary to completely disassemble the dashboard, dismantle eight components, solder to the board on both sides, and only then read the data. Then everything must be assembled in the reverse order. It seems that this is all, but no. Because the data is read in encrypted form, it must be decrypted and only after that we will receive the data necessary for recording the key (cs component, immo id, pin, etc.).

 

So, the order of actions:
1. Dismantle the instrument panel.
2. Read the RH850 R7F701402 data with multi prog and rh850 cable.
3. Prepare the dealer key with vvdi2.
4. Learn all the keys in the car.
5. Mount the instrument panel.

Working time: 3 hours.
