You have to remove BCU not dash and not remove hc11, its no problem in pcb, you solder 6 or 7 wires

[verica]

can you confirm me that this is module (picture that i send in previous post) where km is stored

[bodzio012]

I also was looking for a long time for the first time, hehe, look under the steering wheel to the left at the height of the left knee as you sit behind the wheel, hidden behind the light switch if I remember, small black box

[verica]

[bodzio012]

Yes and you can read write in-circuit without lift any pin with upa. Here is dump for compare ...
