Hello there, 

 

i went through the whole topic regarding PDC retrofit but I am getting different results than what I should expect according to the hints here. 

 

My situation - I had old PDC unit with part number 1Z0919283B I want to add front parking sensors as well. So I bought front sensor loom, new bumper with sensors already fitted, button, speaker and fitted it into a car. 

 

New unit is 1Z0919475G and here comes the trouble - no matter how i try, no matter what i do, i cannot make car communicating with this unit. Tryed coding both addresses, tryed using connection to the actual CAN, then run new wires to the new CAN - no change. Then I swapped with new gateway - my actual one is 1K0907530Q, I swapped it with 7N0907530C also no change. When i use old can connections, it just downt want to work (no id of unit on diagnostics) when i switch to new can, i get multiple random errors from other units and also engine fan starts spinning. 

 

So my question is - what is a correct combination of this unit, gateway and CAN connection??

ok... had to find solution by myself, its working now.

For the benefit of members who find this thread in the future, can you say how you fixed it please.

 

Problem was in interference on CAN bus - once I terminated old cut comfort CAN and run new CAN wires to drivetrain CAN it started working.
