Here is the Audi Air Suspension Control Unit.
It has 2 micro chips.
The first microcontroller.
The 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.
General appearance
Connect module with vvdi prog.
Read and write Motorola MC912D60 secured chip.
Updated!
The firmware flash helped! There are no errors when increasing the speed. I was driving at 160 km/h and the car dropped to the first position.
