Hello,
The car has DPF off (made by somebody).
There are some problems with it:
1. Can't read/write by OBD Audi A6 C6 2.0 TDI EDC16U31 using MPPS. I was waiting 30min but no result...
2. Any VCDS functions that requires "Security access" doesn't work.
DTC-s are clear.
I made BDM (see in attachment).
Any solution?
