Back in a days I've used to own VW Touareg V10 TDI, it was from 2005 model year. Back then (in 2012 maybe) I've bought MPPS adapter cable with software and was able to read, save and write back ECU data for both ECUs(there are 2 of them there).
Now I have VW Touareg V10 TDI but from 2008 model year. The problem is my VAG com reads that both ECUs have 0 reflash attempts and every status bit is zero, however I'm unable to read ECU data using MPPS it just hangs. I've read on the net that those ECUs can have some kind of factory lock.
The solution proposed on the web is to extract ECUs from car, disassemble them, solder some pins on PCB which will turn on some different boot mode and then read ECU data with MPPS.
My question is if it is possible to read those ECUs without extracting from car and disassembling them?
P.S. I'm going to make some engine hardware tuning on this vehicle so ECU tune is a must.
Thank you in advance
