TCU Module: Continental Siemens VDO

UDS shows Compression Type 1, but I am having a hard time finding which compression this is.

Any help would be appreciated :)

Thank you guys!

Any info on the algorithm?

Hello.

Sorry if asking and someone had already answered elsewhere.

What means Compression 11 for Audi A6 dashboards (Fujitsu)?

I would like to see decompressed data in the ODX I have for 4G8930934R/0225.

Thanks.
