Car model and year: VAG Cars like a Touareg 3.0 TDI 2008 and A4 3.0 Petrol
Purpose: Read and write ECU data.
Best VAG ECU programmer:
1. Kess clone does VAG without troubles by OBD and Tricore on some ecu’s.
Just remember to use the software from cd. Don’t use anything else.
I also heard that EU Red versions are already reworked devices. So maybe no need to pay much more for a reworked one.
Check this shop for best Kess clone:
Kess V2 OBD writes edc17cp44: Success!
Car & ECU: EDC17CP44 Q7 / Touareg via OBD
Review: I have done edc17cp44 obd many times with kess
it is a virtual read need to have alientech databank access.
Btw, ktag readout also can be written with kess but have not tried it yet
2. I would recommend you as well a ktag with red pcb for t-protection and full reads/ backups. Did with clone edc17c74 without problems.
Ktag reads edc17cp44: Success!
