Hi
I have story with Volvo V70 XC 2000.
Someone before me change TCU module and install TCU from 2 wheel drive in this car (this is 4WD).
Now i have constatnt software error inside TCU and ECU. TCM-0048.
So, i need change SW inside TCU to correct version.
My ask: any possiblity to write correct software to this TCU, or only online connection to Volvo platform for independent workshop? Or visit to authorised service?
