Read Audi air suspension control unit by VVDI PROG

 This is the Audi air suspension control unit.

The first microcontroller.

Second microcontroller.

In general, there was a problem that at a speed of over 120 km/h, the air suspension dropped into an error for all 4 level sensors, when dropping below 120 km/h, all errors disappeared. It was decided to reflash the unit. It contains 2 Motorola microcontrollers. Xhorse vvdi prog programmer can flash and read them.

The main board of the unit.

Connect the module with vvdi prog.

Select MCU- Motorola MC68HC(9)12- MC912D60 Secured. Read and back up both eeprom and flash data.

UPDATED.
The firmware helped! There are no errors when increasing the speed. I was driving at 160 km/h and the car dropped to the first position.
