Hello, my vehicle is audi a3 2007 1.6 bse engine.
Indicator warning lights are on in my vehicle.
These:
ABS, ESP and Handbrake led blink
Oil, oil sensor, coolant, brake pad, washer fulid...

Cluster No: 8P0920931A 0560

I checked all related components via vcds. Canbus reads all components correctly.

I can test the indicator via VCDS, there is a ROM error on the immobilizer. 16346...

I have read with the devices I have, but I have not succeeded.

Devices I have:
1. Odyssey
2.VCP
3.VCDS
4.KKL
5.Ch341 eeprom.

I think the problem is with the indicator. I can share 24c32 smd read result. Do you think the problem is software or hardware? Should I change the indicator?
I can accept flash file for Odis.

24c32eeprom and vcds scan file in the attachments..

Thank you.

The Micronas MCU flash memory is very likely corrupted.
For repair, it is not enough to have a dump of eeprom.
Search the internet and you will see that this is a very common problem with these dashboards type.
For repairs, you will most likely have to use a special tool such as enigma or X-tool.

Unfortunately, I do not have these devices. I can buy from Aliexpress. I have Odis vas5054, I can flash it if we can find the bin file.
Thank you

I think you have faults in the car not in the odometer
check how many faults there are in the ABS

Thank you for your answer.
There are no errors in abs. I scanned with vcp, vcds and odis.
